SenTec 3051 Rosemount 3051cd Differential Pressure Transmitter With High Quality

PMS3151DP/HP Differential pressure / high static pressure differential pressure transmitter is a pressure signal measured by the low pressure side as the reference end. it has two ports and process pipe connection.

The working principle of metal capacitance differential pressure / high static pressure differential pressure transmitter is that when the pressure acts indirectly on the surface of metal measuring diaphragm (elastic measuring element) of different thickness through isolating diaphragm and conductive medium, the diaphragm produces small deformation, the maximum shape variable does not exceed 0.1mm, and the high precision measuring circuit converts this small deformation into a voltage signal which is linearly related to the differential pressure signal, which is linearized. Temperature compensation, and then use a special chip to convert the voltage signal into an industrial standard 4-20mA current signal or 1-5V voltage signal. The high precision integrated circuit adopted by the high sensitivity of the metal capacitance pressure sensor and the measuring diaphragm detection circuit contains the linear and temperature compensation circuit inside, so the whole transmitter can achieve high precision and high stability.

Metal capacitive pressure sensor has high overload resistance and excellent performance in micro-pressure measurement, and it is also a necessary product in a variety of complex industrial environment.
