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.

What is a pressure gauge with output signal?

The multi-functional intelliGAUGEs present a cost-effective and, at the same time, reliable solution for nearly all pressure measurement applications. They combine the analogue indication of a mechanical pressure gauge, needing no external power, with the electrical output signal of a pressure sensor. 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 Ex ia. For pressure gauges with nominal sizes 100 and 160 mm, the electrical output signals can also be combined with switch contacts. In addition to Bourdon tube, diaphragm and capsule pressure gauges with output signal, WIKA also offers absolute pressure gauges with output signal and also differential pressure transmitters and differential pressure gauges with output signal.

What is a differential pressure transmitter?

The model DPGT40 differential pressure transmitter from WIKA is a differential pressure gauge with integrated working pressure indication and output signal. As soon as a signal transmission is required and, at the same time, a differential pressure should be readable on site, the DELTA-trans of the DELTA-line product family is used. In addition to the differential pressure, the DELTA-trans differential pressure transmitter with output signal can also display the working pressure with the aid of the integrated working pressure indication.

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).

Why does one have filled pressure gauges?

The filling fluid serves as damping for the moving parts within the case. As a result, damage caused by vibration and increased wear on the moving parts can be prevented.
