Pressure sensors and transmitters differences and introduce

Pressure sensors are usually refers specifically to a non-standard signal output mV component level products, is the core component of the pressure transmitter , the signal is non-standard , users Engine Coolant Temp Sensor need to be designed specifically for pressure calibration and signal processing circuit ; Due to weak signals , long distance increases the need for the amplifier ; pressure transmitter is written from the sense, also the pressure sensor , but the output signal as the standard common signal , such as 4 ~ 20mA, 1 ~ 5V , etc., can long-distance transmission , and with the standard instrumentation package . While its pressure value has been calibrated , the user simply by setting range of the instrument can be used .
