Protect the transducer from weather conditions such as rain, snow, ice, and
salt water.
6.1
Ambient temperature
The temperature coefficient of zero signal and sensitivity are compensated. To
obtain optimum measurement results, you must comply with the nominal
(rated) temperature range.
Because of its structure, the arrangement of the SGs is sensitive to tempera
ture gradients. Temperatures that are constant and at best slowly changing
have a favorable effect on accuracy. After significant temperature changes
(moving from cold areas into warm areas, etc.) we recommend waiting long
enough for the sensor to reach thermal equilibrium.
6.2
Moisture and corrosion protection
The force transducers are encapsulated and are therefore insensitive to
moisture. Series KDB force transducer provide degree of protection IP64 and
are made of rustless materials.
With stainless steel force transducers, please note that acids and all materials
which release ions will also attack stainless steels. Any resulting corrosion
could cause the force transducer to fail. In this case, appropriate means of
protection must be provided.
We recommend protecting the transducer against long-term exposure to
moisture and weather conditions.
6.3
Deposits
Dust, dirt and other foreign matter must not be allowed to accumulate
sufficiently to divert some of the measuring force, thus invalidating the
measured value (force shunt).
