Maintenance

12.1 Maintenance tasks

This chapter describes the maintenance of physical device components.

12.1.1 Pressure compensation filter

Keep the pressure compensation filter (1) free from contamination.

A0038667

Pressure compensation filter

A0043756

Pressure compensation filter

12.1.2 Flushing rings

By using flushing rings, the process isolating diaphragm can be cleaned without

removing the measuring device from the process.
For more information: contact the Hauser sales office.

12.1.3 Exterior cleaning

Notes on cleaning

• The cleaning agents used should not corrode the surfaces and the seals

• Mechanical damage to the process isolating diaphragm, e.g. due to pointed objects, must

be avoided

• Pay attention to the degree of protection of the measuring device
