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 circuits dependent upon the pointer position of the indicating measuring instruments. 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.

for further approvals see page 9

Absolute pressure gauge model 532.53 with switch contact model 831.21

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 and electronic contacts are available. Inductive contacts can be used in hazardous areas.

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
