Position transducers with resistive and collector track made from conductice plastic for direct, accurate measurement of travel in display or feedback applications.
Novotechnik LWH linear tansducers offer a high resolution (0.01 mm) combined with a stroke length of up to 900 mm permits the accurate measurement of linear displacement.
Rack and pinions or similar devices are not required because the design of the transducers is such that they may be built directly into the mechanical system. Tighter tolerances on the extruded body combined with a special surface treatment permit high operating speeds and reduced wear.
A pivoting front bearing over comes „stickslip“ type of operation even where some angular or out of parallel errors are present. The technique for fixing and making connections to the resistance track ensures the highest degree of reliability even under harsh working conditions.
By mounting overhead on difficult-to-reach machines it is possible to premount the clamps to the mounting surface and then simply “snap-on” the transducer. The transducer has mounting grooves on all four housing surfaces. Thus the transducer can always be mounted with the resistance element directed upwards, independent of the mounting surface. Erosion particles from inside the transducer will therefore not remain on the resistance element, improving the lifespan of the sensor.
