PDT11 ordinary differential pressure transmitter

Characteristics: High precision, long-term stability; Unilateral pressure, good overload protection. Small size, light weight, strong resistance shock; Continuous adjustment of zero and full scale in the external.

Profile: PDT11 differential pressure transmitter uses capacitance sensor core body, integrated by one, fundamentally eliminated the installation stress and seal failure, so the measurement is accuracy, stable and reliable. It is suitable for many kinds of media which is matching the contact materials. The differential pressure transmitter's measurement part is mainly composed of capacitor plate, center of diaphragm, rigid insulator, fill fluid and isolation diaphragm. When measuring, the process pressure which is rolled in the high and low pressure side will be transferred on the measuring diaphragm which is in the center of the sensor in room δ  through the fill fluid. The measuring diaphragm is an elastic element, its displacement is changed with the differential pressure( For the GP gauge pressure transmitter, the atmospheric pressure is like the pressure side which is exerting on the sensor diaphragm. The low pressure side of the AP absolute pressure transmitter remains a reference pressure). The maximum displacement is proportional to the pressure. The enlarged circuit which is on the measuring diaphragm's two capacitor plates is linear transferred to 4--20mA two-wire standard signal and export.
