Conditions on site

Protect the transducer from weather conditions such as rain, snow, ice and
salt water.

4.1 Ambient temperature

The temperature effects on the zero signal and on the sensitivity are compen­
sated.
To obtain optimum measurement results, the nominal (rated) temperature
range must be observed. Constant, or very slowly changing, temperatures are
optimal. Temperature‐related measurement errors are caused by heating on
one side (e.g. radiant heat) or by cooling. A radiation shield and all‐round ther­
mal insulation produces noticeable improvements, but must not be allowed to
set up a force shunt.

4.2 Moisture and humidity

Series S2 force transducers are protected against moisture. The transducers
reach the protection class IP68 per DIN EN 60259. Nevertheless, the force
transducer must be protected against permanent moisture influence.
The transducer must be protected against chemicals that could attack the alu­
minum, potting material or the cable.
The transducer can also malfunction due to corrosion. Implement protective
measures if this danger exists.
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 force to be measured, thus invalidating the mea­
sured value (force shunt).
