In recent years, level switches have been widely used, and common level switches include tuning fork level switches, RF admittance level switches, microwave level switches, capacitor level switches, etc. The microwave level switch is currently a widely used type of level switch. But currently there are so many manufacturers on the market, which one is better for microwave level switch manufacturers?

　　Microwave level switch is a type of level switch composed of a transmitting device and a receiving device. The transmitter and receiver are installed face-to-face. The transmitting device emits microwaves to the receiving device, and when the microwaves are blocked by an object, the receiver outputs a relay signal. Microwave blockage switches are widely used in various industrial applications that require reliable non-contact level detectors.

　　As an essential on-site instrument in modern production, microwave level switches have the following main uses: they can effectively prevent the material level meter from being full in case of inaccurate fluctuations and malfunctions. It can also effectively prevent the occurrence of material shortage and spraying. It can effectively save manpower, improve production efficiency, and ensure safe production.

　　A microwave level switch usually consists of two parts: a transmitter and a receiver placed at both ends of the tank wall. The transmitter emits a microwave pulse towards the receiver, with a frequency of 200 times per second. If there is a completely emitted or absorbed interfering substance between the two in a straight distance, the pulse will not reach the receiver. When the receiver loses the signal, it will trigger a state change and drive a relay to indicate high or low levels. Sensitivity can be adjusted according to different measurement media.
