Additional information
* Transducers allow optimum adaptation of output current or output voltage to the measurement range. The transducer is preset at delivery to provide an output signal of 4 ... 20 mA (MWI) or 0 ... 10 V DC (MWU) between the starting point and the end point of the measurement range.

Mounting note When you attach the wire, it should be pulled out straight in line with the wire outlet. Recommendation: A 5 mm wire extension is recommended before the measurement starting point. This prevents the wire snapping back to the stop on rewinding.
