Operation on site

3.1 Ambient temperature

For optimum measurement results, keep to the rated temperature range. The
best conditions are constant or very slowly changing temperatures. Measure
ment errors due to temperature are the result of uneven warming (e.g. radiant
heat) or cooling. A radiation shield and all round heat insulation provide noti
ceable improvements. However, they should not be allowed to form any kind
of force leakage.

3.2 Humidity

Humidity have no effect on the measurement capability of the transducer, pro
vided they are within the specified limit values (protection system IP67 in ac
cordance with DIN EN 60529).
NOTE
Moisture should not be allowed to penetrate the free end of the connec
tor cable.

3.3 Ambient pressure

Ambient pressure should be between 0 and 5 bar. Please note that changes
of pressure alter the zero point:

[% sensitivity/10 mbar]

3.4 Contamination

Dust, dirt and other foreign bodies should not be allowed to accumulate to
such an extent that part of the measured force is diverted to the housing so as
to falsify the measured value (force leakage).
