PGS21.160 Bourdon pressure gauge with WIKA switchable contacts

Description

The PGS21.160 Bourdon pressure gauge with WIKA switching contacts is used for monitoring differential pressures, the instrument allows switching and display.

Wherever process pressure needs to be specified locally and circuits need to be switched at the same time, the PGS21.160 GAUGE switch finds its application.

Switch contacts (electrical alarm contacts) make or break the electrical control circuit depending on the position of the instrument pointer. 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 837-1) and regulations for the on-site indication of the working pressure of pressure vessels. Magnetic contact pins, reed switches and electronic contacts are available as switch contacts. Electronic contacts and reed switches can be used to trigger programmable logic controllers (PLCs).
