DPGS43HP.160 differential pressure gauge with switchable contacts WIKA

Description

The DPGS43HP.160 differential pressure gauge with switchable contacts from WIKA is used for monitoring differential pressures, the instrument allows switching and display.

Where process pressure needs to be specified locally and circuits need to be switched at the same time, the DPGS43HP.160 GAUGE switch finds its application.

Switch contacts (electrical alarm contacts) form or break circuits depending on the position of the pointer of the indicating instruments. The switch contacts are adjustable over the full range of the dial (see DIN 16085) and are located mainly under the dial, but also partly on the top of the dial. The instrument pointer (actual value indicator) moves freely over the full scale range, independent of the setting.
You can adjust the set cursor using the removable adjustment key in the window.

You can also set multiple contacts to a single set point. The contact is triggered when the actual value pointer moves above or below the desired set point.

The pressure gauge is manufactured in accordance with DIN 16085 and meets all the requirements of the relevant standards (EN 837-3) and regulations for the on-site indication of the working pressure of pressure vessels.
Magnetic contacts, reed switches, inductive contacts and electronic contacts are available as switch contacts. Inductive contacts can be used in hazardous areas. Electronic contacts and reed switches can be used to trigger programmable logic controllers (PLCs).
