Wiring
The sensor is provided with an integral 1 m long
φ
4 mm four core PVC sheathed cable with cores in red,
black, green and white. Red and black cores are for frequency signal while green and white are for
temperature monitoring through a thermistor. In case specially ordered, PU sheathed cable can be
provided.
