Installation of cables
Wiring
of the
sensor
should be routed separately or screened from heavy conductor lines, as in extreme
cases inductive peak voltages can destroy the sensors despite the integrated protective circuit. Screened
cable or twisted lines are recommended, especially for longer cable runs > 5 m.
Units with strong fields nearby
, e. g. high power walkie-talkies, or noise sources in the lower frequency
range, e. g. long, middle or short wave transmitters should not be operated close to the sensors or additional
measures have to be taken in order to eliminate incorrect operation.
