Differential Pressure Gauge with diaphragm & bellows
MDI series
*APPLICATIONS
All stainless steel material is suitable for corrosive media. Used with all liquid and gas process media, provided that these do not corrode stainless steel, do not crystallize and are not highly viscous. Particularly used in measuring flow, indicating levels, detecting
clogged filters and etc.
*DESCRIPTION
The process medium chambers (+) and (-) are separated by a diaphragm. The difference in pressure between the (+) and (-) in medium chambers deflects the diaphragm. This deflection is transmitted to the pointer via a push rod causing a pointer deflection in proportion to the differential pressure. Metal bellows seal the two pressure chambers off from the gauge case.
