Description

The PRSSM-LD is a low-pressure diaphragm gauge featuring a corrugated diaphragm designed for corrosive, crystallizing, or highly viscous media. It offers measuring ranges from 0–1 kPa up to 0–25 bar, including vacuum and compound options. Available in 4″ and 6″ dial sizes, it provides wetted materials such as 316L stainless steel, Hastelloy alloy, or PTFE, with overload protection of 5 to 10 times full scale (up to 40 bar). The gauge supports threaded or flange process connections and features a stainless-steel case with glass or safety-glass window. Available in dry or liquid-filled versions and rated IP65, the PRSSM-LD is ideal for chemical, petrochemical, oil and gas, and other harsh industrial environments.
