Pressure Sensor Transmitter
Pressure Sensor Transmitter Working principle
The NP93420 series is made by using the piezoresistive effect of semiconductors and micromachining technology. In the specific crystal direction of the single crystal silicon wafer, the process of lithography, diffusion and other semi-conductors are used to fabricate the Wheatstone bridge to form the sensitive diaphragm, which changes slightly when it is subjected to external forces. The resistance of the bridge arm is changed by the change of the resistivity, the output of the excitation voltage signal is changed (one pair is bigger and the other is smaller), after computer temperature compensation, laser resistive adjustment, signal amplification and other processing means and strict assembly detection, Calibration and other processes, the production of a standard output signal pressure transmitter.
