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 com-
pensated.
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
thermal insulation produce noticeable improvements, but must not be allowed
to set up a force shunt.
4.2 Moisture and humidity
Series S2M force transducers are protected against moisture. The trans-
ducers attain protection class IP67 per DIN EN 60259. Despite this, force
transducers must be protected against permanent exposure to moisture.
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 some
means of protection 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 vary, and
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 meas-
ured value (force shunt).
