Industrial type suitable for corrosive environments where the fluid medium does not clog connection or corrode stainless steel. Built to withstand corrosive, highly viscous and crystallizing medium. diaphragm mechanically linked to movement, allowing use of a metallic diaphragm at low pressures. Eliminates system liquid filling and permits overpressurization up to five times the full scale range.
Housing bolts limit maximum pressures to 600 PSI.
