The differential pressure transmitter uses the principle of differential capacitance detection. When the pressure on both sides of the diaphragm is inconsistent, the measuring diaphragm in the chamber will be displaced, and the displacement is proportional to the pressure difference. The capacitance change is converted into a 4~20mA two-wire current or voltage signal through circuit processing, and can be equipped with 458 protocol or HART communication protocol function.

ARTang differential pressure transmitter is for low range pressure measurement for air and gases. The pressure ranges 0 ... 1 mbar up to 0 ... 70 bar, the best accuracy of the differential pressure transmitter can be ±0.075%FS. The transmitter is rugged and vibration-resistant, and the range, zero point and damping are continuously adjustable on site. It can be widely used in the chemical, gas and oil filed.
