NOTE
When the cable is grounded as explained, the metallic parts of the
sensor head, the screen of its cable, the transmitter housing and the
screen of the signal cable to external system are all connected to
each other. After this, the whole system can be grounded from one
point only. If the grounding is made via several points (sensor head,
transmitter housing, signal cable), make sure that the different
groundings are made to the same grounding potential. Otherwise,
harmful grounding currents may be generated. If you do the
grounding via the transmitter housing, use one serrated lock washer
between a mounting screw and the housing; the lock washer breaks
the paint on the housing.
