Stable Output High Sensitivity 20mA NP-93420 Pressure Sensor Transmitter
NP93420 series diffusion silicon pressure sensor all use imported chips, after careful structural design, signal processing and assembly, and in strict accordance with national standards for testing and production of a new generation of pressure sensors. The series of products have stable output, high sensitivity and accuracy, and good temperature characteristics, and strong anti-interference ability.
NP-93420 Pressure Sensor Transmitter Working Principle
NP93420 series is the use of semiconductor piezoresistive effect and micromachining technology, in a single crystal silicon wafer of a specific crystal up, with photolithography, diffusion and other semiconductor processes to produce - Wheatstone bridge, the formation of sensitive diaphragm, when subjected to the action of external forces produce a slight change in resistivity changes, so that the bridge arm resistance changes (a pair becomes larger and a pair becomes smaller) in the excitation voltage signal output, after computer temperature compensation, laser resistance adjustment, signal amplification and other processing means and strict assembly testing, calibration and other processes to produce a pressure transmitter with a standard output signal.
