SENSOR SOLUTION TIPS

Presented by:

Javad Mokhbery (President)


CHALLENGES

• NO 1 sensor fits all applications

• NO easy selection guide

• NON-compatible instrumentation

• NON-standard = long delivery + high cost

• NO good results if mis-installed


OVERCOMING CHALLENGES

1. Define Requirements

2. Pick the right sensor provider

3. Handle & install sensor properly

4. Use Smart Sensors

5. Proper Maintenance (use verification system)


1. DEFINE REQUIREMENTS

• Define application• What are you measuring?• Static / dynamic• Define package size• Define environmental conditions• Define load conditions• Define extraneous load & moments• Define interfacing requirements


2. PICK THE RIGHT SENSOR PROVIDER

• Qualifications

• Experience

• NOTE: Sensor solution company

should be able to

support you long-term


3. PROPER HANDLING & INSTALLATION

• Do NOT tamper with sensing areas

• Do NOT drop

• Do NOT carry unit by cable or apply excessive pull on cable.

• Do NOT overload sensor

• Do NOT use 4-conductor cables for distances over 20 ft

(DONT’S)


• Do monitor output during mounting and installation • Do use stable power supply and prevent high voltage

surges • Do turn the power on• Do apply load in specified direction• Do avoid dirty or loose electrical connections and

follow correct wiring code. • Do use remote sense wires when cable length > 20 ft • Do use flat, parallel and clean mounting surfaces • Do respect required clearances – avoid friction • Do use proper torque and mounting hardware • Do use TEDS

(DO’S)

3. PROPER HANDLING & INSTALLATION


4. USE SMART SENSORS

•

(Transducer Electronic Data Sheet)– Simplifies the interfacing of sensors– Facilitates multiple sensors w/ 1 instrument – Defined by Template per the IEEE 1451.4 – Minimizes / eliminates errors in scaling & calibration – Will NOT require a specialized technician for setup


5. PROPER MAINTENANCE

• Do NOT exceed max excitation voltage

• Do NOT operate over the rated capacity

• Do NOT exceed safe overload

• Do NOT exceed operating temperature

• Do NOT expose to radiant heat

(DONT’S)


5. PROPER MAINTENANCE

• Do verify

(DO’S)


• Do use a sensor verification– Assures sensor accuracy before critical tests– Helps define Re-calibration Intervals– Provides a sense of reassurance– Limits variables if a test goes wrong

5. PROPER MAINTENANCE(DO’S CONTINUED)
