Fischer pressure transmitter Process technology PN 25 | DA09 Diaphragm operated differential pressure gauge

The Model DA09 is designed for measurement of differential pressures of liquids and gases. It can be fitted with a choice optional accessories, including:
Limit detector contacts: delayed-action or magnet actuated switch type Non-contact proximity type limit detector (NAMUR). Principles of Operation The pressures to be compared are connected to adjacent pressure chambers separated by a flexible metal diaphragm. The diaphragm is loaded by a pair of opposing coaxial bellows springs, one one either side of the diaphragm. The bellows on one side also serves to isolate the the surrounding pressure chamber from the gauge mechanism, thus protecting the mechanism from the media. A connecting rod links the diaphragm, through the isolating spring bellows, to the dial mechanism.
