chapter 9 "Specifications".
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary
to the intended use.
Any operation of the instruments deviating from the above provisions must be clearly
discussed, tested and approved in advance in detail with the responsible technical
department of the manufacturer.
Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and
injuries.
▶ Refrain from unauthorised modifications to the instrument.
▶
Do not use the instrument within hazardous areas.
▶
Do not use the instrument with abrasive or viscous media.
▶
Only operate the instrument in the specified pressure and temperature
range.
▶
Do not block the blow-out device on the back of the case.
Improper use is defined as any application that exceeds the technical performance
limits or is not compatible with the materials. Checking against improper use is the
responsibility of the operator.
Any permanent operation in the overload range is not permitted. Over the highest
permissible operating pressure up to the overload limit, the models PG81 and PG91
operate outside their specifications. The overload range is intended to prevent damage
to the models PG81 and PG91, as part of a pressure vessel system, during the pressure
containment test.
The overload limit must never be exceeded, even when failures occur in the end-use
application. Loads above the overload limit can cause irreversible damage, which can
lead, for example, to permanent measuring errors.
Any permissible operating conditions (e.g. pressure and temperature ranges, environ-
mental influences, shock or vibration) must be observed.
