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 vehiclesas well as ship telegraphsRudder and propeller systems for shipsControl drives for systems in the field of energymanagement and chemical industryLifting gears and slewing mechanisms of cranesand excavatorsTail vanes for meteorological measurementsAs dancer potentiometers for textile and paper machineryAs 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.
