A pressure sensor study and research

Abstract

The correlative introduction and analysis of a kind of industrial field pressure measurement sensor is carried out in this paper by us. The principle of work and power supply circuit of pressure sensor is studied in detail. The constant current source power supply mode is adopted in this paper, which is very good for certainty of measurement. In order to go a further step to explore sensitivity situation sensitivity performance, finite element analysis research method is taken for the pressure sensor chip for several times. By means of finite element analysis, we know that the pressure sensor has good sensitivity and degree of linearity. This paper provides several important scientific references for researching and designing the pressure sensor.
