The most important four parts of the pressure sensor are the transforming part, the sensitive component, the measuring component and the auxiliary power supply. Ceramic chip or Diffused-silicon is the sensitive componet, SMT is the transforming part.
The pressure sensor is generally composed of sensitive components, transforming components, measuring components, etc., and sometimes an auxiliary power supply is added. The conversion element is to convert the output of the sensitive element into a signal that is convenient for measurement. Sensitive elements are elements that directly sense the measured and output other quantities that have a definite relationship with the measured. The measuring element transforms the output signal into an electrical signal, which provides convenience for further transmission, processing, display, recording or control. As a product, the auxiliary power supply must be marked with power supply requirements, but it is not a component of the pressure sensor. Nowadays, pressure sensors are generally equipped with auxiliary power supply to facilitate customers' power supply.
These four major components support the pressure sensor, especially the three major components of the transformation element, the sensitive element, and the measurement element. It can be said that the pressure sensor is an indispensable part.
