Causes
Measures
No signal/cable break
Mechanical load too high or
overtemperature
Replace the probe with a
suitable version
Erroneous measured
values
Sensor drift caused by
overtemperature
Replace the probe with a
suitable version
Sensor drift caused by
chemical attack
Analyse the medium
Erroneous measured
values (too low)
Entry of moisture into cable Use the appropriate IP
protection
Erroneous measured
values and response
times too long
Wrong mounting geometry,
e.g. insertion depth too
small or heat dissipation
too high
The temperature-sensitive
area of the sensor must
be inside the medium, and
surface measurements
must be ungrounded
Deposits on the protection
tube
Remove deposits
Temporary or sporadic
interruptions of the
measured value signal
Cable break in connection
