Applies to the pressure detection and control of the process of industrial field, shipbuilding and navigation systems, aircraft

dz0803 diffused silicon pressure sensor system used in all imported chips, after careful structural design, signal processing, assembly test produced a new generation of measuring element. The basic principle is to use semiconductor piezoresistive effect and machining technology, lithography, diffusion, and other semiconductor processes in specific crystal silicon wafer up production of a Wheatstone bridge, the formation of the sensitive diaphragm, when subject to external force micro changes, the resistivity changes, the bridge arm resistance to change (a team of change freshman smaller) excitation voltage signal output, temperature compensated, laser trimming signal amplification, processing means and assembly and test The calibration process is made.
