The radar level gauge is one of the indispensable non-contact measuring instruments in industrial production. As far as "radar" is concerned, we often find it common in our lives. For example, when a car is reversing, it will use radar to detect the distance. Is there any correlation between radar level meters and car radars? If yes, what is the specific aspect?
First of all, we need to understand what is called "radar waves." Radar frequency band is the radar band, which refers to the frequency range of the radar transmission wave. Most radars operate in the ultra-shortwave and microwave bands, with frequencies in the range of 30 to 300,000 MHz (Mega Hertz, MHz), including VHF, UHF, SHF, and UHF (EHF) 4 bands. Car radars include lasers, ultrasonics, and microwave radars, each with different functions such as finding obstacles, predicting collisions, and adaptive cruise control; and using different working principles such as pulse radar, FMCW radar, and microwave impact radar.
Radar Level Meter
However, the Rada level meter is a continuously measuring level instrument compared to an automotive radar. In the process of industrial production, the radar level gauge can monitor the use of materials in designated storage tanks in real time through continuous measurement of material levels to ensure the balance of materials used in various industrial production processes. The radar level gauge is suitable for dust, temperature, pressure change, inert gas and steam presence; no harm to the human body and the environment; it is also not affected by changes in the medium specific gravity and dielectric constant, and does not require on-site calibration Features. Therefore, whether it is to meet industrial needs, or out of cost-saving considerations for users, radar level gauges are cost-effective choices.In general, the signals of car radars and radar level gauges belong to radar waves. This is their common ground, but their differences are very obvious, such as different bands and uses. Most automotive radars use ultrasonic and microwave radars, and the frequency is mostly around 40KHz or 58KHz. However, the radar frequency of radar level meters is much higher than that of car radars. For example, the frequency of a low-frequency radar level gauge is as high as 5.8 GHz to 10 GHz (Note: G=Giga (billion), and 1 GHz is 10 to the 9th power of Hz.)
