Pressure sensor measurement circuit
Source: InternetPublisher:方世玉223 Keywords: Pressure sensors sensor measurements measurement circuits amplifiers Updated: 2020/02/20
It is a pressure sensor measurement circuit. The nominal resistance of the pressure sensor is 120n. The amplifier in the circuit uses an AD521 operational
amplifier with a gain of 100. It is determined by Rs/Rc; the A/D converter uses ICL7107 to digitally display the pressure it measures. The output of AD5 21
can also be connected to an analog or digital voltmeter to display the measured pressure.
