Grounding the Transmitter Housing

In case you need to ground the transmitter housing, the grounding

connector is found inside the housing, see Figure 2 on page 17 above.

Note anyhow that the probe head is connected to the same potential as

the housing. Make sure that different groundings are made to the same

potential. Otherwise harmful ground currents may be generated.

If it is needed to have galvanic isolation of the power supply line from

the output signals, PTU300 can be ordered with optional output

isolation module. This module prevents harmful grounding loops.
