WET-WET Differential Pressure Transmitter

AV700 series is media isolated differential pressure transmitters consists of both isolation membrance differential pressure sensor and integrated circuits. It has characteristics of high precision, good stability, high reliability and good sensibility. It has built-in high-performance microprocessor (MCU) which can correct nonlinearity and compensate temperature drift to measure and control for liquid and gas.
