Description
1. Product Brief
The pressure transmitter adopts sputtered thin film sensor, imported Silicon Diffused Type and ceramic pressure sensor as sensitive element. The special integrated module is adopted. After precise temperature drift, zero point and nonlinear compensation, accurate measurement and transmission of liquid pressure, gas and steam pressure are realized. The ideal monitoring of pressure and vacuum in various places such as factories, mines, enterprises and research institutes should be realized.
Two. Product uses:
Industrial field process pressure control, aerospace and petrochemical industry.
Instruments, medical and food industries, navigation and shipbuilding industry, water conservancy, hydropower, power plants and so on.
