DP Gauges / Indicating Switches



Model PDR02 pressure gauges have two separate, independent Bourdon tube measuring systems, each with its own indicator needle. The two needles indicate their respectively measured pressure on the same gauge scale. These devices can be used to monitor two separate measurement points or to determine differential pressure, such as the pressure between the inlet and outlet of a filter.

Model PDP02 differential pressure gauges have two measuring chambers, which are separated by a diaphragm. The difference in pressure between both chambers causes the diaphragm to deflect, the result of which is indicated by the movement of the needle relative to the gauge scale.

Model PDR04 differential pressure gauges feature two Bourdon tube measurement systems that are linked to each other in a manner that causes only the pressure difference between the two inlets to be indicated by the movement of the needle relative to the gauge scale. This design makes an additional rotary scale, such as used on other double-Bourdon-tube systems, unnecessary.
