Pressure gauges with output signal

Pressure gauges with output signal combine the advantages of the analogue indication of a mechanical pressure gauge, needing no external power, with the electrical output signal of a pressure transmitter. These hybrid instruments are available with all commonly used electrical signals. The sensor works in a non-contact way, without any influence on the measuring signal. Many of the instruments can be delivered in accordance with ATEX with an Ex-i intrinsically safe ignition protection type.

FAQ

What is the function of a three-way valve block?

With upstream pressure equalising valves it is possible to achieve uniform pressure loading from the plus and minus side, to avoid single-sided overpressure loading during both start-up and operation, and also to enable zero point checks during operation.

What is a change-over contact?

When the set point is exceeded, simultaneously one circuit is opened (NC) and one circuit is closed (NO). Changeover contacts are denoted by the number 3 (SPDT).
