Conditions on site

The C10 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 design of the strain gage arrangement
(radially symmetrical shear force transducers), causes extreme insensitivity to
temperature gradients. Nevertheless, constant or very slowly changing
temperatures are 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 different protection classes,
depending on the equipment variant.
