Conditions on site

The PW15B series load cells are covered with a potting mass to protect the
SG (strain gauges) against moisture. The transducers attain protection class
IP67 as per DIN EN 60529. Nevertheless, the load cells must be protected
against permanent moisture influence.

2.1 Protection against corrosion

The load cells must be protected against chemicals that could attack the
transducer body steel or the cable.
NOTE
Acids and all substances that release ions also attack stainless steels and
their welded seams.
Should there be any corrosion, this could cause the transducer to fail. In this
case, appropriate protective measures should be implemented.

2.2 Deposits

Dust, dirt and other foreign matter must not be allowed to accumulate suffi­
ciently to divert some of the measuring force onto the housing, thus invalidat­
ing the measured value (force shunt).
