C9C 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.
5.1

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, nevertheless
temperature gradients can have a negative effect on zero
point stability. 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 prevented.
5.2

Moisture and corrosion protection

The force transducers are hermetically encapsulated and
are therefore very insensitive to moisture. The
transducers achieve protection class IP67.
Despite the careful encapsulation, it makes sense to
protect the transducers against permanent exposure to
moisture.
