Conditions on site

4.1 Ambient temperature

To achieve optimal measurement results the nominal temperature range must
be maintained. Constant but slowly changing temperatures are best.
Temperature gradients in the transducer caused by one−sided heating
(radiant heat) or cooling are very disruptive. A radiation shield and all−round
heat insulation bring about marked improvements. Naturally they must not
form a force shunt.

4.2 Moisture

External moisture and a tropical climate will not impair the function of the
transducer according to the classification of the specified degree of protection
(degree of protection IP 67 to DIN 40 050).
Transducers with nominal loads ≥ 1 MN are not metal−tight.

4.3 External pressure

The external pressure (in air) must be between 0 and 3 bar.

4.4 Chemical effects

The steel housing of the transducers is protected by a powder coating. If used
in difficult environmental conditions (direct weather effects, contact with media
which encourage corrosion) additional protective measures should be
employed by the user. The unit can be painted with commercial protective
paint or a tar−based coating (underseal). The sheath of the connection cable
is made of silicon rubber.

4.5 Deposits

Dust, dirt and other foreign bodies must not be allowed to accumulate such
that they divert part of the measured force onto the housing and so falsify the
measured value (force shunt).
