Liquid Smart Differential Pressure Transmitter Sensor
Liquid Smart Differential Pressure Transmitter Sensor Description:
Liquid Differential Pressure Transmitter Sensor is the result of a combination of self-developed anti-jamming, high stability digital circuits and the introduction of foreign Single crystal resonant silicon sensor technology. Its performance much better than our domestic metal capacitive sensor technology transmitter, and main show in the field zero stability and long-term operation stability, and rapid response.
