Measurement transducers permit optimum adjustment of the output current and output voltage to the measuring range.  The measurement transducer is pre-set at the works so that an output signal of 4 … 20 mA (MWI) or 0 … 10 V DC (MWU) is available.

Hint for mounting

When securing the wire it must be ensured that the wire is straight and vertical in relation to the wire outlet.  Recommendation: Only select the starting position after an unwound length of approx. 5 mm. This prevents the wire hitting the end stop when it is rewound.
