Conditions on site
4.1 Ambient temperature
The effects of temperature on the zero signal and on the sensitivity are com
pensated. To achieve optimal measurement results the nominal temperature
range must be maintained. Temperature‐induced measurement errors are
caused by heating (e.g. radiant heat) or cooling on one side. A radiation bar
rier and all‐round thermal insulation will produce a marked improvement, but
should not form a force shunt.
4.2 Moisture
Extreme humidity or a tropical climate should be avoided if this means that the
classified limit values are exceeded (degree of protection IP65 under DIN
EN 60529).
NOTE:
Moisture must not be allowed to penetrate the free end of the connection
cable or get into the pressure compensation hole.
4.3 Deposits
Dust, dirt and other foreign bodies must not be allowed to accumulate such
that they divert part of the measured force onto the housing and so falsify the
measured value (force shunt).
NOTE:
Foreign bodies must not be allowed to clog the gap beneath the flange
surface.
