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.
