Descripción

The PRLD is a differential pressure gauge designed for cryogenic tanks and closed tank trucks, suitable for measuring liquid nitrogen, liquid oxygen, oils, and other low-temperature media. With a static pressure rating of up to 50 bar and measuring ranges from 0–4 kPa to 0–400 kPa, it is ideal for liquid-level monitoring and filter condition detection. Wetted parts include copper alloy flanges, a 304 stainless-steel compression spring, and an NBR separating diaphragm, housed in a 304 stainless-steel case with a polycarbonate window. Rated IP65 and equipped with an adjustable pointer, the PRLD supports oil-free construction for flammable or explosive gases and offers optional valve manifolds, oxygen-service versions, switch contacts, and process adapters, making it a reliable solution for cryogenic and industrial tank applications.
