C2
The C2 series force transducers are made of rustless
materials. It is nevertheless important to protect the
transducers from weather conditions such as rain, snow,
ice, and salt water.
6.1

Ambient temperature

The effects of temperature on the zero signal and on
sensitivity are compensated.
To obtain optimum measurement results, the nominal
(rated) temperature range must be complied with. The
compensation of the temperature effect on the zero point
is implemented with great care, but temperature gradi­
ents can still have a negative effect on the stability of
zero. Constant or very slowly changing temperatures are
therefore best. A radiation shield and all-round thermal
insulation produce noticeable improvements, however,
they must not be allowed to set up a force shunt, i.e.
slight movement of the force transducer must not be pre­
vented.
6.2

Moisture and corrosion protection

The force transducers are hermetically encapsulated and
are therefore very insensitive to moisture. The transduc­
ers achieve protection class IP67.
Despite the careful encapsulation, it makes sense to pro­
tect the transducers against permanent exposure to
moisture.
The force transducer must be protected against chemi­
cals that could attack the steel.
