  What's the difference between pressure transmitter and pressure sensor?Xi'an Huaheng Instrument Manufacturing Co.,Ltd.will answer you:Many people will confuse the two.What's the difference between pressure transmitter and pressure sensor?

  Pressure transmitter and pressure sensor function is to transform pressure signal into another signal,many users can not distinguish the difference between the two pressure measuring instruments.In practical testing engineering,the pressure transducer's applicable metrological verification rules are JJG882-2004 Pressure Transducer,the pressure transducer's applicable metrological verification rules are JJG860-1994 Pressure Transducer(Static)and JJG624-2005 Dynamic Pressure Transducer.


  Although they are all measuring instruments for converting pressure signals,the difference between them is that there is a given continuous function relationship(usually linear function)between the output signal of pressure transmitter and pressure variables,while the output signal of pressure sensor can only have certain regularity with pressure variables.


  This may be an arbitrary rule,not necessarily a linear function.That is to say,the pressure sensor can output regular signals,while the pressure transmitter needs to amplify and correct the signals to output a set of standard signals.Therefore,pressure transmitter can be said to be a special pressure sensor.
