High performance diffusion-silicon sensor as sensitive measuring element. The housing of the DP transmitter is divided into two chambers filled with silicon oil. The measured pressure acts on both ends of the diaphragm res-pectively, and the differential pressure is transmitted to the pressure sensor through silicon oil. The product is suitable for differential pressure measure-ment of gas or liquid in pipeline or tank, such as oil, chemical industry and water conservancy.

M-DP measures differential pressure in a different way. It has two separate absolute resistance pressure sensors to create separate pressure information for the microprocessor. The microprocessor then performs digital correction and calculation of differential pressure, static pressure and temperature or flow. The structure is compact and strong, making it easy to connect to any primary element.
