How to wire the microwave RF sensor bit switch

　　First of all, it needs to be clear that the wiring of the microwave level switch is carried out under the premise of ensuring safety. Before wiring, power off the microwave level switch and confirm whether the voltage level meets the requirements. At the same time, it is also necessary to verify that the installation holes required between the switch and the measured medium meet the requirements.

　　Secondly, according to the different media that need to be measured, the way of wiring is also different. Generally speaking, the microwave level switch has three pins, namely, the power pin, the output signal pin and the ground pin. For the application scenario of measuring liquid level, the power supply pin and ground pin are usually connected to the power supply for power supply, and the output signal pin is connected to the input port of the control device (such as PLC, relay, etc.). At the same time, it is also necessary to connect the circuit after the switch and the liquid level meter are installed at the same height.

　　For the application scenario of measuring the level of solid materials, there are also some differences in the wiring mode of microwave level switches, mainly in the installation position and circuit connection. During the connection process, it is necessary to keep a certain distance between the solid material and the switch to avoid misjudgment caused by too small material particles. Similarly, connect the power and ground pins to the power supply for power supply, and the output signal pins are connected to the input port of the control device.

　　It is worth mentioning that when conducting the wiring work of the microwave level switch, it is necessary to pay attention to correctly connecting the ground pin. This is a very important work, if the grounding pin connection is not correct or no connection, will greatly affect the use of the switch effect and safety performance. At the same time, pay attention to whether the wiring is tight and firm to prevent loosening leading to circuit disconnection.
