4. Conditions on location
4.1 Ambient temperature
For best results, the device must be operated within the nominal temperature
range. The best operating conditions are constant and, if necessary, slowly
changing temperatures. The specified temperature errors apply if the tempera-
ture does not change faster than 5K/h. One-sided thermal radiation or cooling
should be avoided and appropriate technical preventive measures taken, if
necessary.
4.2 Moisture and dust
The torque transducers comply with protection type rating IP40 as per DIN
40050.
Note: There should be no moisture inside the transducer connector
4.3 Chemical effects
The torque transducers are not protected against chemical effects. They must
not be used in caustic or corrosive environments.
4.4 Deposits
Dirt, dust or other foreign substances should not accumulate so that they can
enter the bearing or the connectors.
