The P4000 pressure transducer for refrigeration pressure applications may be specified with a Shrader depressor fitting for quick connection and installation, says the manufacturer. It incorporates MEMS (silicon micromachined) sensing technology in an all-welded, stainless steel design for compatibility with HFC, HCFC, and ammonia refrigerants. A stainless steel isolation diaphragm provides increased corrosion resistance in hostile environments, the company says. The units are available in pressure ranges of 0- to 100- through 0- to 750-psi absolute or sealed gauge.
