How is the transmitter connected to the pressure sensor? That is to say, how is it wired?
The transmitter adds an amplifying circuit on the basis of the sensor
Pressure sensors are divided into three categories: piezoelectric, piezoresistive and capacitive, and the output signals are varied. But mostly in voltage and current form.For pressure sensors which output in the form of voltage, current and resistance, the transmitter input is regarded as the voltmeter, ammeter and ohmmeter.For pressure sensors that require power supply, they can be powered individually or by a special transmitter. At this time, the power supply of the transmitter is used as the power supply, and the output line is connected with the sensor to supply power.The pressure transmitter is equipped with a pressure sensor, which is usually made into one and has been connected inside.
The pressure transmitter and sensor are made into a whole, and the inside is connected
