PM460 high pressure transducer is made of high-strength, high-elasticity, corrosion-resistant stainless steel. It is a high-reliability, corrosion-resistant, high-long-term stability product specially designed for oil pressure testing of oil wells such as cobalt wells, cementing and fracturing vehicles.
The special structural design and strain isolation technology minimize the zero temperature drift of the transmitter due to the installation stress, and its long-term stability is also greatly improved. The pressure sensitive diaphragm and WECO 1502, 2 inch spherical interface are integrated into one body, and the other components are processed by electron beam welding. The aspect ratio of the weld is unmatched by other welding processes. The whole instrument is integrated to ensure the hammer installation process. And high-intensity vibration during use and reliability under impact.
Components that come into contact with the pressure medium have excellent resistance to mechanical wear and corrosion from corrosive media such as H2S. The thick and shallow structure of the inner bore is effective to prevent blockage of the slurry and facilitate maintenance.
