  • Model 73x.31: Case with safety level "S3" per EN 837
  • All-welded media chamber

Description

These differential pressure gauges are made of highly corrosion-resistant stainless steel and feature an all-metal media chamber to ensure long-term leak tightness (no elastomer sealing elements).

A high overload safety is achieved by the all-metal construction and the close-fitting design of the diaphragm measuring element.

The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments.

The optionally available low-temperature version allows use at temperatures of down to -70 °C [-94 °F].

The safety version is made up of a non-splintering window, a solid baffle wall between measuring system and dial and a blow-out back. In the event of a failure, the operator is protected at the front side, as media or components can only be ejected via the back of the case.

Scale ranges of 0 ... 16 mbar to 0 ... 25 bar [0 ... 0.23 to 0 ... 363 psi] ensure the measuring ranges required for a wide variety of applications.
