The GP-NEMA 4 Series is designed to provide excellent accuracy and reliability in commercial, industrial, and process control applications where high performance and a NEMA 4 weatherproof enclosure is required. The bulk micro-machined transducer features a stainless steel diaphragm with welded construction that contains no O-rings, which makes them compatible with any gas or liquid compatible with 304L stainless steel. Some of the compatible gases and liquids include refrigerants, glycol, motor oil, diesel, hydraulic fluid, brake fluid, water, waste water, Hydrogen, Nitrogen and air. The GP-NEMA 4 Series transducers include a optional NEMA 4 rated, weatherproof aluminum enclosure and an optional NIST Calibration Certificate. Accessory items such as pressure snubbers and pigtail syphons are available to protect the transducers from line pressure surges and extreme operating temperatures. For
