Measuring transducers for potentiometers and resistors
Description
Measuring transducers for potentiometers and resistors
Application
The measuring transducer W-MU is used for the transformation and isolation of a change in resistance into an impressed direct current and direct voltage signal. The calibrated double outputs are switchable between 0-20 mA and 0-10 V or 4-20 mA and 2-10 V.
Function
A constant measuring voltage is applied to the potentiometer in case of 3-wire circuits. The measuring signal generated via the center tap is amplified and transformed into an impressed direct current or in an impressed direct voltage. In case of the 2-wire circuit, the measuring signal is generated using a constant current. The galvanic isolation is realized using an optocoupler. Both outputs are no-load proof and short-circuit proof. Connecting the two outputs is not permissible. An auxiliary voltage is required.
