Pressure sensor type and wiring method
What type of pressure sensor do you buy? What type?. The connection is according to the signal. The analog voltage signals are mostly three wire system, one work voltage is positive, one is the positive pole of output signal and the other is common negative pole.Current signal 4~20mA, usually a two wire system, a power supply, a signal
The line is determined according to the signal. The analog voltage signals are mostly three wire system, one work voltage is positive, one is the positive pole of output signal and the other is common negative electrode.Public and instrumentation equipment
According to the output signal, can be divided into two categories: 1 analog output, usually 3 pin 2 effective digital output, usually can be divided into I2C, SPI, pin 4 to 5. manufacturers each effective pinout differ, treat specific conditions.
