The Model 425 Wing Union Pressure Transmitter is robust and durable. It utilizes the 1502 Wing Union and is suitable for both onshore and offshore installations. The independent pressure-sensing diaphragm minimizes zero drift during torquing and eliminates long-term signal deviation in electric fields. The sensor diaphragm of Model 425 is integrated with the wing union. It adopts a fully welded construction and a patented electron beam welding process with deep penetration, ensuring seal integrity under all electric field conditions. A special assembly process is applied to the Model 425 Transmitter to protect its components from vibration and shock, enabling reliable operation in harsh environments such as rupture or gluing systems. The 1502 Wing Union-compatible assembly is equipped with an Inconel® X-750 diaphragm, capable of handling abrasive and highly corrosive media. This device meets the corrosion resistance requirements of NACE Standard MR-01-75 (1980).
