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.
Steel transducer versions (nominal (rated) forces 25 kN, 50 kN, 100 kN, 250 kN, 500 kN,
1 MN)

Integrated cable
Aluminum transducer versions (nominal (rated) forces 2.5 kN, 5 kN and 10 kN)

Despite the careful encapsulation, it makes sense to protect the transducers against
permanent exposure to moisture.
