The linear transducer model PWA measures the absolute position of the plunger without contact or wear using an inductive resonator measuring system. This consists of an excitation coil which causes an oscillating resonance circuit (moving target) fastened to the plunger to oscillate. This in turn excites the receiver coils fixed in the housing, which are printed on a printed circuit board. The integrated electronics transform these signals (sin/cos) into a signal proportionate to the linear travel. The measuring system is insensitive to electrical and magnetic fields. 0(4) to 20 mA and 0 to 10 VDC are available as standard as analogue signal outputs. CANopen, IO link and SSI are in preparation. The sensor is fastened using at least two retaining clips HK-01 or using sliding blocks ST-01. The sensor can be equipped with ball joints at the front and rear. Alternatively, the sensor's plunger can be designed as a button.

The linear transducers operate according to the differential throttle principle (inductive half-bridges). They consist of two coils which are impermeably cast into a Mu-metal cylinder, where they are protected from vibrations. On displacement through the hollow coil body, a Mu-metal plunger leads to a change in the induction direction in both coils. The linear transducers are designed for an oscillator frequency of 10 kHz. The supply and signal processing are carried out by external modules.

The displacement transducers work according to the principle of the differential choke (inductive half bridges). They consist of two coils which are encapsulated in a Mu metal cylinder in a sealed and vibration-proof manner. A Mu-metal plunger causes an opposite induction change in the two coils when displaced by the hollow coil body. The displacement transducers are designed for an oscillator frequency of 10 kHz. Power supply and signal conditioning are provided by external module modules.

The displacement transducers operate according to the principle of the differential choke, i.e. an inductive half bridge. They consist of two coils which are encapsulated in a stainless steel cylinder ensuring positive protection against vibration, shock, humidity, oil and corrosive matter. A mu-metal plunger core causes opposing changes of inductance when it is displaced through the centre of the coils. The displacement transducers are designed for a carrier frequency of 10 kHz. Other frequencies can be used but may involve changes of output values.

Please note that this product is an accessory. In the "Products" section you will find the corresponding encoders that you can order for your selected article.The linear movement of a flexible steel cable, which can have a length of up to 5 m, is converted into an rotary movement with the aid of a measuring drum. The measuring drum is connected to the shaft of an encoder. In this way a change in displacement of the measuring cable causes the shaft of the encoder to rotate by a directly proportional amount which can be recorded. The restoring force of the spring drive holds the measuring cable tight at all times and prevents any sagging which would otherwise induce an error. The cable is wound up precisely and reproducibly wrap for wrap in the helical groove of the drum. The nozzle, through which the cable enters the drum, is protected with a brush and a bellow to prevent water or dust entering the drum. Two roller units at the cable entry allow for up to 20° <) deflection of the cable.
