Working principle
This product uses a piezoresistive OEM pressure sensor with a stainless steel isolation diaphragm as the signal measurement component, and has been automatically tested by a computer. It uses resistance technology for zero sensitivity temperature compensation over a wide temperature range. The amplification circuit is located inside a stainless steel casing and converts sensor signals into standard signals. The entire product has undergone rigorous testing and aging screening of components and semi-finished products, with stable and reliable performance.
