432.56 diaphragm pressure gauge with switchable contacts WIKA

Description

432.56 WIKA diaphragm manometer with switchable contacts is preferably used for low pressure areas. Through the large working area of the circular, corrugated diaphragm element, small pressure ranges can be reliably measured.

Where process pressure needs to be specified locally and circuits need to be switched at the same time, the Model 432.56 or 432.36 GAUGE switch finds its application.

Switch contacts (electrical alarm contacts) close or open the circuits depending on the position of the pointers 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 entire 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 contact pins, reed switches, inductive contacts – for ATEX requirements – or electronic contacts for PLC triggering are available as switch contacts. For further information on the different switch contacts, see datasheet AC 08.01.
