Deposits

Dust, dirt and other foreign matter must not be allowed to accumulate suffi­
ciently to conduct any of the measuring force around the transducer, thus inval­
idating the measured value. (Force shunt). Also remember to lay the connec­
tion cable so that no force shunts are produced at the lower nominal (rated)
forces (<1 kN). It is ideal if the cable is fixed to the side to which the adapter is
bolted.

Effect of ambient pressure

The force transducer's response to changes in air pressure is negligible.
Please note that the force transducer can be used at gage pressures up to
5 bar.
The following table shows the effect of air pressure on the zero signal, subject
to the nominal (rated) force being used.
