The manufacturers of pressure sensors use many different terms for the various designs of measuring instruments, such as pressure sensor, pressure transmitter, pressure transducer, etc.
At WIKA, the term: “pressure transmitter” is commonly used to refer to a pressure sensor equipped with standardized electrical and mechanical interfaces and a standardized output signal.
The working principle of a pressure transmitter is as follows: The pressure of the medium to be measured is guided via a standard process connection thus affecting the internal pressure sensor element. The internal electronics converts the raw sensor signal into a filtered, amplified, temperature-compensated and standardized signal, such as the 4…20 mA signal. This output signal is delivered via a standardized connector or a cable to the subsequent unit for signal processing. Read more about the pressure transmitter A-10 for general industrial application.
