These are high level output, low differential pressure transducer designed for wet to wet differential pressure measurements of liquids or gases. A fast-response capacitance sensor and signal conditioned electronic circuitry provide a highly accurate, linear analog output proportional to pressure. Both unidirectional and bidirectional pressure ranges are available for applications with line pressure up to 250 psig. All parts exposed to the pressure media are stainless steel and elastomer seals. The unit has a NEMA 4/IP65 rated package to withstand environmental effects. They can be supplied with an optional 3-valve manifold assembly for ease of installation and assembly. The 3-valve manifold is a machined brass body requiring no internal pipe connections, thereby eliminating the risk of internal leaks. The manifold’s rugged, yet compact, construction requires minimum space for installation and use. The bleed ports allow for total elimination of air in the line and pressure cavities. If the unit is ordered with the 3-valve manifold, the system is shipped completely assembled and ready for a wall or piping mounting.
