Conditions on site

Protect the transducer from moisture and dampness or 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

Force transducers in the KD/STZ/KDB type series reach the protection class
IP64 as per DIN EN 60529.
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 Chemical effects

The steel transducer housings are protected by a powder coating. They must
not be exposed to adverse ambient conditions (direct weather conditions, con­
tact with corrosive media).
The un‐coated force application areas are greased to protect them against
corrosion.
