Description
The PRLD is a high-performance differential pressure gauge specifically engineered for cryogenic tanks and closed tank trucks. It is ideally suited for monitoring liquid nitrogen, liquid oxygen, oils, and other low-temperature media. Featuring a static pressure rating of up to 50 bar and measuring ranges from 0–4 kPa to 0–400 kPa, it provides reliable solutions for liquid-level monitoring and filter condition detection. The instrument’s wetted parts comprise copper alloy flanges, a 304 stainless steel compression spring, and an NBR separating diaphragm, all housed within a rugged 304 stainless steel case with a polycarbonate window. Rated IP65 and equipped with an adjustable pointer, the PRLD is available in oil-free versions for flammable or explosive gases. Optional accessories include valve manifolds, oxygen-service versions, switch contacts, and process adapters, making it a robust and versatile solution for cryogenic and industrial tank applications.
