NOTE
Moisture must not be allowed to penetrate the free end of the connection
cable. Otherwise the characteristic values of the transducer could change and
therefore cause measurement errors.
4.3 Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate suffi
ciently to divert some of the measuring force onto the housing, thus invalidat
ing the measured value (force shunt).
4.4 External pressure
The external air pressure for the transducer with measuring ranges w500N
must lie between 0 and 5bar. Please note that pressure fluctuations can shift
the zero point.
