The process medium chambers (+) and (-) of these differential pressure gauges are separated by a diaphragm. The difference in pressure between the (+) and (-) -medium chambers deflects the diaphragm. This deflection (measured travel) is transmitted to the pointer via a push rod causing a pointer deflection in proportion to the difference in pressure. Metal bellows seal the two pressure chambers off from the gauge case.
Metal supporting elements guarantee overload protection.
The two downward outgoing process connections (G1/4 i) are made of corrosion resistant solid materials.
For mounting purposes, it should be noted that:
(+) represents high pressure and (-) low pressure.
The pressure connection position may be varied according to the installation conditions DT-GM 8608 176.
The measuring element is tamper proof.
The gauges can be used with gaseous, liquid and also chemically aggressive media as well as in aggressive environments, but not in highly viscous or crystallizing media.
