Abstract
An electronic pressure sensor is described that includes a hollow stainless steel insert within a plastic outer housing. A piezoelectric pressure sensor is mounted to one end of the insert while the media to be measured flows into the other end. The insert protects the plastic outer housing from the pressure of the media. A microcontroller reads a digital signal from the pressure sensor and converts the signal into a digital output such as RS-232 or RS-485.
