Elasto-flex pressure sensors provide the ideal method of isolating pressure measurement devices from process fluids, with numerous advantages over commonly used diaphragm type sensors. The 360 degree design is self cleaning, eliminating the problem of seal cavity blockage that is common with diaphragm type pressure sensors. Elasto-flex pressure sensors contain only one wetted part, with integral flange gaskets provided by the one piece moulded sleeve. A variety of sleeve materials is available to provide optimum abrasion and corrosion resistance for different process fluids. Because of the high volume of sensing fluid used compared to other pressure sensor types multiple instrument arrangements are possible. Elasto-flex pressure sensors easily operate gauges, sensors, transducers and transmitters.
