T1800 high temperature Spray-diaphragm pressure transmitter is a product which is characterized by high temperature-proof, wide range and high accuracy. It is widely used in testing gas and liquid pressure, such as water, oil, light hazardous liquid and gas.
Spray-diaphragm core refers to spray an insulation layer on the core by chemical method. Then Wheatstone bridge of metal diaphragm type and temperature compensation are sprayed on the insulated body.
At last, cover a layer of insulation material on the metal diaphragm resistance. The Wheatstone bridge of metal diaphragm will deform in accordance with the core deformation, which is affected by pressure and give a linear output.
