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 happens when a model 7 differential pressure gauge with separation diaphragms made of elastomers is operated below the ambient temperature specified in the data sheet?

Below the permissible ambient temperatures, the accuracy deteriorates significantly, since the diaphragm (which is either made of FPM / FKM or NBR) stiffens at low temperatures.

What is an isolating amplifier?

The isolating amplifier transmits digital signals from the hazardous area. The signal transmitters can be either sensors per DIN 19234 (NAMUR) or mechanical contacts. The input is securely isolated from the output and the power supply in accordance w ...
