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 circuits 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.

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
Instruments with switch contact for PLC applications
