| Abstract: | The characteristics of sensing elements of pressure switch in the solid state pressure sensor MPX series are introduced,and the switch application circuit consisting of MPX pressore sensor is offered.This circuit can take the advantages of the switch application function of the pressure sensor abundantly.The design can meet the engineering appliction byusing the few ordinary components. In chemical industry production,gasometers can be used to store gases,and be served as buffers usually.But the gasometer is sometimes bled to be shrivelled.This accident can be avoided if the kind of pressure switch device made up of MPX pressure sensor is applied to the working protection of gasometer. |
