Description

Position transducers with resistive and collector track made from conductice plastic for direct, accurate measurement of travel in display- or feedback applications. 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 (recognizable by the position of the middle mounting groove directly across from the resistance element), 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.

Example Applications

Application: Injection Molding Machines

Product: Position Transducers LWH and TLH

In injection molding machines, all values relevant to the process of manufacturing thermoplastic and duroplastic items are measured and stored. The positions of various mechanical parts are measured, as well as pressure and temperature. The goal is to achieve a consistently high quality of molded items and a short preparation time during tool changes.

Function: Either the position transducer LWH or TLH is used for measurements, depending on the mechanical construction of the customer's various products. The effective lengths range from 75 mm on ejection pins and dosing cylinders, to 1500 mm on injection molding aggregates and clamping units.

Production in shifts, shorter cycle times and low tolerances of the molded items require a high reliability and precision from the employed position measurement system.
