multiple sensors for in-situ test process

monitoring:

- force sensors of our proprietar y

and patented design believed to be the most

repeatable in the world. We provide customers

with a calibration set and do recommend to

check the calibration quarterly, but typically,

the sensors maintain the factory calibration

for years (!),

- high-frequency acoustic emission sensors of

our proprietary design, with very high

sensitivity to tiny local asperities, nano/micro

cracks, etc.Their unique amplitude-frequency

characteristics allows for detection of much

tinier phenomenon than that observed with

commercial AE sensors,

- wear sensors, from standard (0.5 micron)

to high (25 nanometers) resolution;

- contact and surface electrical resistance

sensors, with very wide ranges from milli-

Ohms to mega-Ohms, that allow for better

detection of the onset of film or coating failure;

- temperature and humidity sensors;

high-frequency multi-channel data-

acquisition system, with user specified data

sampling rate up to 100 khz, for detection of

almost instantaneous tiny micro-contact events in

sophisticated test sequences,

optional integrated digital microscopy for

precision sample positioning, digital video of the

dynamics of surface failure during testing, and

images of wear tracks, indents and scratches;

optional integrated atomic force microscopy

for imaging of test surfaces, wear tracks, indents

and scratches both periodically during testing and

post-test;

optional temperature (up to 1,000 C), vacuum

and humidity chambers;

wide variety of configurations, mostly easily

upgradeable in the field. You can purchase a basic

unit now and then many different options at any

time later.

The UMT testers are covered with a 1-year full warranty on manufacturing defects, both parts and

labor. Should you ever have a technical question, problem or request, CETR staff will always be

ready to support.CETR maintainis a 24-hour response time of all of our customer's inquiries.

Though this UMT Catalogue includes numerous modules and features, the variety of advanced

testing needs for fundamental research and practical applications is much greater. Therefore,

Motor Controllers

Description

The Control Unit is a part of the UMT Basic System. It is composed of a Pentium basedcomputer with CETR UMT control software, CETR data viewing software, Windowsoperating system and a 16-bit data acquisition board with up to 16 channels and up to 200kHz sampling rate. The Control Unit also houses motor controllers. Included are a 15” LCDmonitor, keyboard, mouse, network interface adapter and a CD-RW drive.

The UMT software controls all motors and instrumentsin the Testing Unit in both semi-automatic and fullyautomatic modes with easy to write test scripts. The testscripts are composed of a series of sequences that list thechannels and parameters to be recorded such as friction,load, acoustic emission, displacement, etc. Each sequenceis composed of one or more steps that define themechanical actions of the UMT Testing Unit such as speed,load, distance and duration. Option files for each drive andsensor combination simplify reconfiguring the UMT fordifferent test schemes.

During testing, the multiple signals are displayed real-time as both graphs and values. Also, data files can berecorded for each test sequence for later retrieval andanalysis. User-chosen software filtering of the data allowsfor reduction in file size.

- Ultra-low force ball-on-disk tests- Friction, stiction, and wear tests on magnetic media - Diamond stylus scratch tests

Typical ApplicationsThe Models FUL and FVL are 2-axis Friction/Load Sensors which are used to simultaneously and independently measure friction force and normal load. Their primary use is for testing stiction and friction forces as well as wear between surfaces such as heads and disks that are used in computer disks drives. Coefficient of friction is automatically calculated from the normal load and friction force in the UMT control software. Each axis of these sensors has strain gages that compose a balanced full bridge circuit. Our proprietary design guaranties the highest degree of precision and repeatability.The force sensors have a small square strain pin that extends slightly from the bottom. The strain pin has a threaded hole that accepts a screw for mounting an ultra-low stiffness suspension such as a disk drive head suspension. A mounting plate is used to attach the sensor to the vertical carriage of the Testing Unit. Four counter-sunk holes are provided for bolts to secure the sensor to the carriage.

There are several types of force sensors, suspensions, adapters and upper specimen holders, The specimen holders can be divided into two groups - those with 0.13” square or round shafts and those with 0.5” shafts. The chart below shows the relationship between the different components. For example, follow the column on the left side of the chart. The model FL sensor can

accept a suspension with a 0.13” square shaft. That suspension can accept any specimen holder with a 0.13” square or round shaft. When no suspension is needed, the specimen holder can attach directly to the sensor. For another example, a model DFH sensor can accept a matching suspension with a

rigid adapter or it can accept the rigid adapter directly. That rigid adapter can accept any specimen holder with a 0.5” shaft or a clamping adapter for smaller size shafts.

A suspension is a spring device which may be installed between the force sensor and the upper specimen holder. It compensates for variations in the distance between the force sensor and the surface of a moving lower specimen when the lower specimen is not flat. Rigid adapters are used to attach specimen

holders to sensors when suspensions are not needed. See Guide to Suspensions and Adapters.

Wire Probe Holder (AM30C135B)This holder is used when measuring the very low contact resistance of the point of contact between a wire upper specimen and a conductive lower specimen such as a semiconductor wafer. Each end of a loop of wire is clamped in the holder in contacts that are insulated from each other. The constant current source is connected between one end of the wire on the holder and a spring contact on the lower specimen. The voltage sense is connected between the other end of the wire and a second spring contact on the lower specimen. (See schematic on previous page.) This eliminates the resistance of the probe and wire from the measurement of the resistance of the contact between the wire specimen and the lower specimen.

BallProbe Holder (AM30B305)This holder is used when measuring low contact resistance between a 4mm ball and a conductive lower specimen. The holder made of gold plated brass to reduce resistance. The holder can be used for sliding or penetrating tests. This holder should be used instead of regular upper ball holders with ECR-0.5 or ECR-1.

Spring Contact with Carbide Point (AM30B1073A)The Spring Contact with Carbide Point is used to make electrical contact to a lower specimen. The carbide point can be placed on a specific location such as a pad on a semiconductor wafer. Two spring contacts are used for surface resistance measurements between two points on the lower specimen. One spring contact is used for ECR measurements with ECR-1K, ECR-100K, or ECR-1M.

Insulating Disk (AM30B984)The Insulating Disk is used to electrically isolate the upper specimen from a model DFH force sensor. It is placed between the force sensor and the Rigid Adapter for model DFH sensors.

Insulating Plate for Reciprocating Drive (AM30B1274)The Insulating Plate for Reciprocating Drives is used to electrically isolate the lower specimen from specimen table of a reciprocating drive.

The 350º C high temperature chamber has acontainer for holding liquids such as motor oil.The container has two sections. The lower bowlsection attaches to the spindle of the rotary driveand holds the lower test specimen (usually astainless steel disc) with a screw through itscenter. The spinning action of the bowl forces theliquid in the bowl to the outer lip. From there theliquid flows into the stationary upper section ofthe container where it pours back onto the lowerspecimen. In this way the liquid is continuouslycirculated over the lower specimen.

The liquid container can hold a stainless steeldisc (PN M30B295B) which has a 2.75” diameterand is 0.26” thick. The distance from the top of thechamber to the top of the disc is 1.5”.

The liquid container can be replaced by aspecimen table which has a 3.80” diameter. Thisallows larger specimens to be dry tested in thechamber.

T esting Applications

The elevated temperature chamber has an exterior made of Teflon™ and can be easily mounted on the reciprocating drive frame. The chamber has an access slot on the top cover to permit coupling of the upper test specimen that is inside the chamber to the friction/load sensor. The heating element and temperature sensor are located inside the chamber. A cable connects the chamber to the UMT Testing Unit. A computerized temperature controller uses the output of the temperature sensor to precisely control the chamber temperature. See the UMT Basic System page of the catalog for model numbers of the UMT that have a built-in temperature controller. Otherwise, a stand alone temperature controller must be used. The temperature can be set in a test script, and the measured temperature is continuously displayed and recorded.

Humidity Control Unit

The Humidity Control Unit provides a flow of humidified air to the Humidity/Gases Chamber. It has a fitting on the rear panel to connect to a stand-alone air compressor or to house air. There is a flow regulator on the rear panel to control the input air flow up to 30 SCFH (cubic feet per hour). The incoming air passes through a filter and then is split into two paths. One path goes through a dryer and the other path goes through a humidifier. There are separate flow regulators for dry and wet air on the front panel. The dry and wet air are fed through separate hoses and mixed at the input port of the Humidity/Gases Chamber.The Humidity/Gsaes Chamber has a humidity and temperature sensor connected to the UMT data acquisition channels. Humidity is controlled by monitoring the sensor output and adjusting the ratio of moist air to dry air with the flow controls on the front panel.

Description

Chiller Control Unit

Description

The Chiller Control Unit provides specimen cooling down to -20ºC. It uses the same chamber as the 150ºC Elevated Temperature and is controlled by the same temperature controller. The chiller requires an external air supply which flows through a heat exchanger where it is cooled. The cooled air then passes through a hose into the chamber via an attachment that mounts to the chamber.

DescriptionThe Heated Vacuum Table can hold a disc, wafer or

similar flat specimen on it with an externally supplied vacuum to the black tube in the lower right of the photographs. There are threaded holes in the table for mounting of specimens without vacuum. See page 2 for the hole layout drawing.

Thin specimens can be heated up to 350º C. A heating element and a temperature sensor are located inside the table. A computerized temperature controller uses the output of the temperature sensor to precisely control the table temperature. See the UMT Basic System page of the catalog for model numbers of the UMT that have a built-in temperature controller. Otherwise, a stand alone temperature controller must be used. The temperature can be set in a test script, and the measured temperature is continuously displayed and recorded.

The Heated Vacuum Table has a base that contains the vacuum chuck, heating element, temperature sensor, and two fans that keep the outside of the base cool. It can be used as a stationary table or mounted on a Model R20HE linear drive as shown in the top photograph.

A cover with a clear window sits on the base. A two piece Teflon lid provides a top of the cover. The two pieces of the lid slide together after the upper and lower specimens are in place forming a 0.75” diameter hole for the upper specimen holder.

ensVariable Rolling-to-Sliding Fixture

DescriptionThe Variable Rolling-to-Sliding Fixture is a bearingassembly inside a liquid holder that is mounted on thespecimen table of a UMT Lower Rotary Drive, as in thephoto on the right. The drawing on the lower right showsthe components of the fixture. The bearing assemblyconsists of a loading plate, an upper disk, a lower disk, abearing cage or separator, and either 3 short rollers, 3long rollers, or 3 balls. The rollers or balls are held at a120 º angle from each other by the bearing cage which issupported by a small bearing assembly. The loadingplate transfers a load to the bearing assembly.The lower disk rotates with the liquid holder. The upperdisk and the loading plate are held stationary by theapplied load. The load is applied by the UMT carriageequipped with a 6D force sensor, and a self-levelingholder.The self leveling holder and adapter are centered overthe loading plate of the fixture. The carriage is lowered toapply the load, which keeps the upper raceway disk fromrotating. The 6D sensor’s Fz output provides feedbackfor controlling the applied load, and its Tz output is themeasured when the drive is rotating.The bearing cage (red) allows the bearing assembly tobe configured in 4 different ways.1. 0% Sliding: When the 3 balls are used in the 3 roundopenings in the cage, they roll between the upper andlower disks without sliding. This is because they areeach contacting the disks at a single point on a singleradius. The balls roll at the same rate as the linearvelocity of that single radius.

torque

2. 15% Sliding: When the 3 short rollers are used in the 3short rectangular radial openings in the cage, they rolland slide between the upper and lower disks. They slidebecause the rollers are each contacting the disks along astraight line and the radius of the disks changecontinuously from one end of the line to the other. Therollers can only rotate at one speed but the linear velocityof the disks is different at every point along the line ofcontact. The difference between the linear velocity of thedisks at one end of the roller and the linear velocity of thedisks at the other end of the roller determines thepercentage of slippage.

3. 35% Sliding: When the 3 long rollers are used in the 3 long rectangular radialopenings in the cage, the percent of sliding to rolling is greater than with the shortrollers. This is because the difference between the linear velocity of the disks atone end of the roller and the linear velocity of the disks at the other end of the rolleris greater.4. 65% Sliding: When the 3 long rollers are used in the 3 long rectangular slantedopenings in the cage, the percent of sliding to rolling is greater than with the longrollers in the radial openings. Not only is there a difference in the linear velocities ofthe disks from one end of the roller to the other, but the angle of the roller to thedirection of the rotating disks increases the percentage of sliding. The greater theangle of the roller from the radial position the greater the sliding. For example, at90º there would be no rolling at all.

CCC EEETTTRRR




The Impedance Measurement and Recording option measures the electrical impedance of soft conductive surfaces such as skin. It is composed of a data acquisition channel, a signal conditioning board which is mounted in the enclosure on the vertical carriage, a cable and a coaxial probe on a suspension. The probe tip material is brass and Nylon. A 10 kHz alternating current source is applied between the center conductor and the outer ring of the probe. The resultant voltage is scaled to indicate impedance in ohms. Currents and voltages are small and safe under all conditions from short circuit to open circuit. A spring suspension allows the probe to maintain uniform contact over uneven surfaces. The Impedance Measurement and Recording option should be used with the model DFM-0.5 (5N) Force Sensor.

The Arm Support for In-Vivo Skin Studies supports an arm in the proper position for making in-vivo friction and electrical impedance measurements. It consists of four parts:

- an arm rest holds the arm still and comfortable during testing. It can be adjusted to level the area of the skin under test.

- a slotted platen attaches to the arm with velcro straps. Its purpose is to hold the skin flat in the slotted test area. A bubble level on the platen aides in adjusting the arm rest.

- a support plate covers the base of the UMT Testing Unit and provides a stable surface for placing the arm rest in a convenient position.

- an extension fixture supports the friction/load sensor with a probe so that it can be moved forward to be positioned above the arm rest.

Cross-Hair or Surgical-Sutures Friction Test Holders

FeaturesConsistent tensioning from specimen to specimen90º, 45º, and 22.5º angles between specimens and sliding motion

DescriptionThe Cross-Hair or Surgical-Suture Friction Test Holders are a pair of clamping and tensioning fixtures for holding two wire-like specimens for the purpose of measuring friction when they are rubbed against each other. The upper holder mounts to either a suspension or directly to a friction/load sensor. The lower holder mounts on the Hair Tress Holder (AM30C726A) shown on the previous page or on the linear motion drive. The clamping and tensioning mechanisms of both upper and lower holders are identical.The wire (3) is clamped (1) at the ends of the holder. A groove (2) in the holder near each clamp keeps the wire (3) aligned with the holder. One end of the holder is hinged (8) to allow releasing the tension while installing and removing the wire. Screw adjustments control the amount of tension (4) and release (5) for consistent tensioning from specimen to specimen.Each holder mounts on a base (6) that has a set of holes (7) for orienting the holder at 1 of 3 different angles relative to the motion of the reciprocating drive. The simplified drawing shows the holders at 90º to each other. When they are orientated so that the motion of the drive is in the direction of the red arrow the sliding distance on each wire will be the same. When they are orientated so that the motion of the drive is in the direction of the black arrow the sliding distance on the lower wire will be the length of the stroke, while the sliding distance on the upper tress will be zero.

Testing Applications- Friction and wear tests of fibers, wires,

surgical sutures, and hair care products.

The acoustic and thermal isolation enclosure has been specifically designed to reduce effects of external noise and vibrations, as well as to stabilize the thermal environment during nano-scale experiments. The enclosure is made from high-performance noise-absorbing and thermo-insulating materials. The enclosure door is held firmly by four latches. It is equipped with a port for passing cables to equipment inside the enclosure. The high-end model IE-1 has an impressive appearance, its heavy weight contributes to the isolation properties. Its four casters allow the enclosure to be easily moved, and five threaded levelers provide a stable base for the enclosure. The floor below the enclosure should be properly supported. The low-cost model IE-2 provides an affordable enclosure solution.
