GMP500-TLT differential pressure/high static pressure differential pressure transmitter is a pressure signal measured with the pressure side as the reference end,and has two ports and process piping connections.
Working principle of the metal capacitive differential pressure/high static pressure differential pressure transmitter is that when the pressure is indirectly applied to the surface of the metal measuring diaphragm (elastic measuring element) of different thickness through the isolating diaphragm and the guiding medium, the diaphragm is generated. Tiny deformation, the maximum shape variable does not exceed 0.1mm, the high-precision measurement circuit converts this tiny deformation into a voltage signal linearly related to the differential pressure signal. After linearization and temperature compensation, the voltage signal is later used by a dedicated chip. Convert to industry standard 4-20mA current signal or 1-5V voltage signal. The high-sensitivity integrated circuit used in the high sensitivity and measurement diaphragm detection circuit of the metal capacitive pressure sensor contains linear and temperature compensation circuits, so the entire transmitter can achieve high precision and high stability.
