A: The sensors people talk about now consist of two parts, namely the sensing element and the conversion element.
The sensitive element refers to the part of the sensor that can directly sense or respond to the measured quantity.
A conversion element is the part of a sensor that converts the measured quantity sensed or responded to by the sensitive element into an electrical signal suitable for transmission or measurement.
Since the output signal of a sensor is generally very weak, it needs to be modulated and amplified.
With the development of integrated circuit technology, this part of the circuitry, along with the power supply circuitry, is now also integrated into the sensor. This allows the sensor to output a usable signal that is easy to process and transmit.
B: The so-called sensor refers to the sensitive element mentioned above, while the transmitter is the conversion element mentioned above. A pressure transmitter is a pressure sensor that outputs a standard signal; it is an instrument that accepts pressure variables and converts them proportionally into a standard output signal.
