Principles of Operation

The measuring element ("waveguide"), consists of aspecial nickel-alloy tube.

A copper conductor is introduced through the length ofthis tube. The start of measurement is initiated by ashort current pulse.

This current generates a circular magnetic field whichrotates around the waveguide. A permanent magnet atthe point of measurement is used as the markerelement, whose lines of field run at right angles to theelectromagnetic field. In the area on the waveguidewhere the two fields intersect, a magneto-strictive

effect causes an elastic deformation of the waveguide,which propagates along the wave guide in bothdirections in the form of a mechanical wave.

The propagation velocity of this wave in the waveguideis 2830 m/s, and is nearly insensitive to environmentaleffects (e.g., temperature, shock, contamination).

The component of the wave which reaches the far endof the waveguide is damped there, whereas thecomponent which arrives at the signal converter ischanged into an electrical signal by reversing the

magnetostrictive effect. The wave travel time from itspoint of origin to the signal converter is directlyproportional to the distance between the permanentmagnet and the signal converter. A time measurementthen allows the distance to be determined withextremely high accuracy.

Design

The transducers are made to the same safety andreliability standards for use in the harshest conditions:

The electronics unit is compactly designed usingSMD technology. The boards are protected in a space-saving, rugged aluminum extruded housing.

The waveguide is protected in the extruded aluminumhousing.

Quality

Each and every transducer undergoes a speciallydesigned, computer-controlled testing procedure whichincludes 100% checking of all specified data.

The drawings below show that the Linear Position Sensoris longer than the cylinder of the same stroke length. Thesensor overhang on the head end of the cylinder, asindicated by dimension A, may be eliminated by addingstop tubing, which effectively increases the gross strokeof the cylinder. The recommended stop tube lengths are

provided in the table below for each bore size. Theexamples show that the electrical stroke of the sensor willalways match the net stroke of the cylinder.

As a result of the limited sensing range of the sensor, itwill overhang at the cap end of the cylinder by the amountof dimension B.

Example B: To eliminate sensor overhang on the head end of a 2.0" bore cylinder, add 1.0" of recommended stop tube length.The cylinder gross stroke becomes 13" and the net stroke remains 12". Specify a sensor with an electrical stroke of 12". Notethat the electrical stroke equals cylinder net stroke length.

Example C: To eliminate sensor overhang on the head end of a 5.0" bore cylinder, add .625" of recommended stop tube length.The cylinder gross stroke becomes 12.625" and the net stroke remains 12".
