Applications

  • Control and regulation of process values
  • Monitoring of plants and switching of circuits
  • Pressure measurement independent of fluctuations in the atmospheric pressure
  • Monitoring of vacuum pumps, packaging machines and condensation pressures, determination of vapour pressure in liquids

Special features

  • High overload safety, long service life due to metal media chamber sealing
  • Media chamber protected against unauthorised access
  • Also available with liquid-filled case for high dynamic pressure loads or vibrations
  • Instruments with inductive contacts for use in hazardous areas with ATEX approval
  • Instruments with electronic contact for PLC applications

Description

Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the model 532.5x switchGAUGE finds its use.

Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the pointer position of the indicating instrument. The switch contacts are adjustable over the full extent of the scale range (see DIN 16085), and are mounted predominantly below the dial, though also partly on top of the dial. The instrument pointer (actual value pointer) moves freely across the entire scale range, independent of the setting.

The set pointer can be adjusted using a removable adjustment key in the window.

Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.

The pressure gauge is manufactured in accordance with DIN 16085 and fulfils all requirements of the relevant standards (EN 837-3) and regulations for the on-site display of the working pressure of pressure vessels.

As switch contacts, magnetic snap-action contacts, reed switches, inductive contacts – for requirements to ATEX – or electronic contacts for triggering a PLC are available.
