WM12070B Differential Pressure Transmitter is assembled by piezoresistive-silicon differential pressure sensor, and the housing is the aluminium alloy structure similar with WM120B and surface is coated with epoxy resin paint. WM12070B Differential Pressure Transmitter is moisture-proof, waterproof, and corrosion-resistant. It can work in harsh environments and outdoor conditions. The transmitter has a small volume and light weight, which can be installed on the process pipeline and supported. Compared with transmitters that require a base or bracket, it greatly reduces installation and maintenance costs or connected through the press-leading tube. it is widely applied in the air supply for boiler, underground ventilation and other electricity and mining industries, as well as the process control field of automated pressure detection for the super clean workshop. It is suitable for differential pressure or pressure measuring for medical treatment, chemical fiber, electricity, dustless house and etc. The transmitter uses proprietary current output with wide temperature compensation and provides a stable zero regardless of the transducer environment.
