with inductive magnetoresistive or optoelectronic measuring systems
Today potentiometric Angular Position Transmitters attain a still more status with regard to the analogue measuring technique as far as high-quality measurement tasks are concerned due to the favourable value for money.
They are mainly used for
- Power and braking control elements for railway vehicles
- as well as ship telegraphs
- Rudder and propeller systems for ships
- Control drives for systems in the field of energy
- management and chemical industry
- Lifting gears and slewing mechanisms of cranes
- and excavators
- Tail vanes for meteorological measurements
- As dancer potentiometers for textile and paper machinery
- As well as for measurements in the field of mechanical,
- apparatus and medical engineering
Potentiometric transmitters have either a high-resolution element of conductive plastic or a high-resolution gold or constantan wire with various resistance and angle values.
They are available in various sizes as single-turn or multiple-turn potentiometers or in a multiple design.
For adjustment of the measuring range almost all series can be provided with short-circuiting tracks, taps and function windings.
Some models are available with incorporated Signal Converter providing current or voltage outputs in configuration of 2, 3 or 4 wires.
To ensure reliability in very dirty atmospheres, oil-filled potentiometers are available.
Moreover, to provide protection for all potentiometers from mechanical damage, dusty and damp industrial atmospheres a series of casings with a degree of protection IP 40 to IP 68 is available which can be equipped with gearing and limit switches.
