1. Power cable connection.
The power cord connection of the three-wire pressure sensor is relatively simple, and generally only needs to be connected to the power cord of the sensor. Typically, the color of the power cord is red or black, depending on the model and brand of the sensor. When plugging in the power cable, you need to pay attention to the voltage and current values of the power supply to ensure that they match the operating parameters of the sensor.
Second, the output signal line connection.
The output signal connection method is one of the core connections of the three-wire pressure sensor. Typically, the color of the output signal line is green or blue, depending on the model and brand of the sensor. The output signal cable connection method requires the signal cable to be connected to the signal output socket of the sensor and ensure that the connection is secure. When accessing the output signal line, you need to pay attention to the polarity of the signal lines to ensure that they match the polarity of the sensor output signal.
3. Grounding wire connection.
The grounding wire connection is another core connection method for three-wire pressure sensors. Typically, the color of the ground wire is yellow or black, depending on the model and brand of the sensor. The function of the ground wire is to connect the reference ground of the sensor with the measurement system to ensure the accuracy and stability of the measurement results. When accessing the grounding wires, it is necessary to pay attention to the connection of the grounding wires to ensure that they are firmly and reliably connected to the sensor grounding terminals.
