Applications

  • Control and regulation of process values
  • Monitoring of plants and switching of circuits
  • For measuring points with increased differential overpressure
  • Filter and pump monitoring
  • Level measurement on closed vessels

Special Features

  • Differential pressure measuring ranges from 0 … 16 mbar
  • High working pressure (static pressure) and high overload safety up to 40 bar
  • 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 DPGS43.1x0 switchGAUGE finds its use.

Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the pointer position of the pressure gauge. 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 differential 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.
For further information on the different switch contacts please see data sheet AC 08.01.
