Pressure gauges are widely used in the industrial field and, in particular, in production processes as gauges for relative, absolute and negative relative pressure.
The classic pressure gauges we can find in industry are dial gauges. The dial gauge consists of a sensitive element (Bourdon spring) which transfers the pressure measurement to an index where the pressure reading can be taken by means of a graduated dial.
Other widely used pressure gauges are piezoelectric pressure gauges. Among the Delta OHM pressure gauges, the HD2124.2 is a portable instrument with two inputs and a display able to carry out absolute, relative and differential pressure measurements and temperature measurements through the use of an electronic module which acts as a link between the instrument and the TP704 and TP705 series of pressure probes.
