Fig. 5.1 T21WN connection diagram
The transducer generates an internally galvanically isolated measurement
signal. The grounds must not be bridged directly on the transducer, otherwise
measurement errors may occur depending on the supply and analysis device.
If necessary they can be bridged on the supply and analysis device. The
"control signal" is used to test the transducer. It produces a maximum signal of
+10 V, for example (with clockwise load). The modulation level is 4.5 V up to
the supply voltage. The reference voltage is the supply ground.
The transducer has a ready for measurement signal. If the output is returning a
HIGH level, normally the measurement electronics are working. With a LOW
level there is an error.

Cable extension

Extension cables must be the shielded, low‐capacitance type. We recommend
the use of HBM cables that comply with these requirements.
