La description
YD series diffused silicon differential transmitters are consist of both isolation membrane differential pressure sensor and integrated
circuit, Has characteristics of high precision, good stability, high reliability and good sensibility. Also can build high-performance
microprocessor(MCU)which can correct nonlinearity and compensate temperature drift. Achieve accurate data transfer, local
equipment diagnoses and long-distance bidirectional communication.
