PM431 Intelligent high accuracy pressure transducers adopts imported high-quality pressure sensor chip, built-in characteristic correction memory E2PROM to correct sensor temperature environment, pressure and input/output characteristics, and through CUP microprocessor operation, automatic temperature compensation, nonlinear correction , signal amplification, V / I conversion and A / D conversion, output 4 ~ 20mA or 1~5V standard signal. The transmitter’s small form factor, excellent temperature characteristics, pressure characteristics and input and output characteristics can replace ordinary pressure transmitters. Widely used in the fields of automated detection and control of petroleum, chemical, electric power and environmental protection.
