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.

For further approvals, see page 8

Differential pressure gauge model 732.51

The low-temperature version POLARgauge ® allows operation with ambient temperatures down to -70 °C [-94 °F].

Cases with safety level 'S3' are fitted with 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.

The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.

Special features

  • Differential pressure measuring ranges from 0 ... 16 mbar to 0 ... 40 bar or 0 ...10 inH 2 O to 0 ... 600 psi
  • High operating pressure and high overload safety up to 40 bar [600 psi]
  • Models 732.31 and 733.31: case with safety level “S3” per EN 837
  • All-welded media chamber
  • QR code on dial links to instrument-specific information

The scale range of a pressure gauge defines the scale start value and full scale value of the scale printed on the dial of the pressure gauge. The correct scale range depends on the process pressure of the respective application and the process conditions. There are predefined standard scale ranges for pressure gauges in accordance with European and American standards. For special display ranges, please contact WIKA support. Ideally, the process pressure of the application should be approx. 2/3 of the full scale value of the pressure gauge. Example: For a process pressure of 40 bar, for example, a pressure gauge with a scale range of 0 to 60 bar would therefore be recommended.
