with potentiometric, inductive or optoelectronic measuring systems

For measuring linear displacements on machines and converting them into electrical signals for teletransmission purposes - linear displacement transmitters of the potentiometric, inductive, incrementally or absolutely coded type can be used, depending on their application.

In additon to other applications they are used on

• bending machines an injection moulding machines
• actuator drives of valves and traps
• transport vehicles
• thickness, distance and pressure gauges

Potentiometric linear displacement transmitters comprise high-resolution wirewound resistance elements, capable of measuring length up to 1 m with high accuracy and a linearity of ± 0,1%.

For protection against mechanical damage, plunger with sintered metal bearing and pull-back spring (optional), wiper guide, wiper and resistance element are encapsulated in a robust aluminum casing, degree of protection IP 65.

For measurements relevant to safety, transmitters of this type are available with double-track potentiometer.

Inductive linear displacement transmitters comprise a non-contact differential inductor system providing high linearity and resolution, capable to perform reliable measuring ranges from 0 to 0.5 mm up to 0 to 500 mm even under extremely severe environmental conditions.

A separate or built-in oscillator/demodulator unit transforms the linear displacement of the plunger controlled differential inductor system into a current or voltage output signal.

Incremental and absolute displacement transmitters comprise by design an optoelectronic angular position transducer, degree of prote-tion IP 65 to protect against dust and the effects of moisture, hinged by means of a driving pin and a toothed belt, guided inside the profiled aluminium. Transmitters of this type are preferably used for actual value determination of great measuring lengths on sawing machines in wood- and stone-working industry.

For the determination of measuring length in the range of several meters the program offers extra rope length transmitters (further information see data sheet “Rope Length Transmitters”).

Accessories: For indicating and monitoring the measurured lengths picked up by these systems, indicating instruments and limit indicators are available (further information see data sheet “Signal Indication” and “Signal Converters”).
