[China Aluminum Industry Network] As we all know, smart radar level gauges use the principle of echo ranging to work, but how many people know how to use radar level meters to use electronic waves to measure the distance of objects, In the life, what places will use radar level gauges? Under this problem, Xiao Bian took everyone to understand the working principle of smart radar level gauges.
When the smart radar level gauge works, it transmits an antenna to the measured target and emits microwaves. The microwave of the measured target is received by the receiving antenna. The signal processor compares the transmitted signal with the received signal to calculate the distance to be measured. Because the microwave is in the transmission route. There are attenuation and interference reflections, so the key to measurement is to be able to receive the reflection echo and identify the effective echo.
A special time extension method in which the high-frequency radar level gauge operating time can be converted into level signals by electronic components can ensure stable and accurate measurements in a very short time. It transmits and receives through the antenna system through very short microwave pulses with very low energy. The following are some of the features and application advantages of high-frequency radar level gauges in use:
1, can measure a higher range of 70 meters, 3 mm error, without being affected by temperature changes, dust, steam, is the leader in similar products;
2. It has a wide range of applications and can be used for continuous level measurement of oil storage tanks, bitumen storage tanks, petroleum liquefied gas, reactors, petrochemical industry wastewater tanks, and steel blast furnace steel. It is also widely used in the fields of winemaking, food industry, and pharmaceutical industry;
3, integrated structure, non-contact speaker;
4. A variety of explosion-proof standard certifications in Zone 1 and Zone 2;
5. The instrument can be set and programmed through user-friendly buttons, HART protocol and operation window. The advanced multi-functional software can eliminate the interference of stirrers or other obstacles.
The above is related to Xiao Bian's introduction to the working principle of smart radar level gauge. I believe that after reading the above article, you also have a new understanding of the smart radar level gauge.
