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. 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.

Angular Position Transducers with inductive magnetoresistive or optoelectronic measuring systems. 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. 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. 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.

The signals representing angle and length of a telescopic crane are important measuring data. Determination of such measuring data is performed by means of tilt angle and rope length transmitters. The determination of the jib angle is performed by a magnetically damped pendulum system, the swing of which is measured with a redundant high-resolution conductive plastic potentiometer. The output signal is provided in form either of two resistance signals or via the built-in signal converter in form of two current or voltage signals. Linear measurement is performed according to the draw wire measuring principle. One makes use of a multiwire measuring cable, which is wound multilayered on a cable reel provided with a pullback spring. A mechanical spindle lead screw nut ensures, that the rope is rewound and unwound exactly layer-by-layer. The number of drum revolutions, being proportional to the measured length is determined by a redundant potentiometer system voltage or current output.
