CONDITIONS ON SITE

6.1

Ambient temperature

The effects of temperature on the zero signal and on the sensitivity are compensated. To
achieve optimal measurement results the nominal temperature range must be
maintained. Temperature‐induced measurement errors can be caused by uneven cooling
or heating (for example by radiant heat). A radiation shield and all‐round heat insulation
bring about marked improvements. They must not form a force shunt.
6.2

Moisture

Extreme humidity or a tropical climate should be avoided if this means that the classified
limit values are exceeded (degree of protection IP50 under DIN EN 60529).
6.3

Air pressure

Changes in air pressure have no effect on the force transducer since it is not hermetically
sealed.
6.4

Chemical effects

The aluminium enclosure of the transducer is protected by a powder coating. If used in
difficult environmental conditions (direct weather effects, contact with media which
encourage corrosion) additional protective measures should be employed by the user.
