Pressure gauges with output signal

For all established electrical signals with non-contact sensor

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
FAQ

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).

Does the height above sea level have any effect on the measuring result of relative pressure measuring instruments?

No, this has no effect, since it is always the pressure differential from ambient that is measured.
