tunable rf bandpass filter.Microwave level switch manufacturer takes you to learn about microwave level switches

　　The microwave level switch consists of three modules isolated from household appliances: transmitter, receiver, and amplifier. The transmitter and signal receiver are assembled in pairs with each other. To achieve good characteristics, it is necessary to ensure that the installation of signal receivers and transmitters is firm and rigorous. The transmitter asks the signal receiver with microwave mirror measurement capability to push a microwave beam. The microwave beam is pushed 200 times per second. If a material absorbing microwave occurs on the same plane as the signal receiver, the microwave beam will not reach the signal receiver, so the signal receiver will not be able to detect the microwave beam. When the signal receiver detects a microwave beam and the situation changes, it will cause the solenoid valve to pose.

　　The time delay for the microwave series products to change to the action of the solenoid valve is set by two independently adjustable potentiometers; One solenoid valve is used to set the signal to be reasonable, and another solenoid valve is used to set the signal to be interrupted. The action of the solenoid valve always changes the signal situation and maintains it after the set time cycle. Any changes during the delay period may cause the delay to start from scratch. The sensitivity of the signal receiver is adjusted by a potentiometer, which can compensate for the reflectivity and absorption between different materials. Similarly, we can also adjust to change the situation even if only a partial microwave beam is detected. The system has two potentiometers for sensitivity adjustment, each for coarse and fine adjustment. When a signal interruption is detected, the solenoid valve can be set to be powered on or powered off, and this working mode is set by the binary switch on the signal receiver. Three LED indicator lights for amplifier setting permissions, each used to indicate the power supply;
