排列三012走势图组选 www.gfzd.net As we all know, the intelligent radar level meter is to use the principle of echo distance to work, but how many people know that only the use of radar level meter is how to use electronic waves to measure the distance of objects in life and what The local will use only radar level meter for this problem below by the small tape with everyone know the working principle of intelligent radar level meter.
The intelligent radar level meter transmits the antenna to the measured object at the time of operation. The microwave is received by the receiving antenna. The signal processor compares the transmitted signal with the received signal to calculate the measured distance. Since the microwave is transmitted in the transmission route There is attenuation and interference reflection, so the key is to be able to receive the reflection echo, and identify the effective echo.
High-frequency radar level meter running time can be converted into a level signal by electronic components A special time extension method can ensure a very short period of time stable and accurate measurement. It is transmitted and received through the antenna system by transmitting very short microwave pulses of very low energy. The following is the high-frequency radar level meter in the use of some of the characteristics and application advantages:
1, can measure up to 70 meters range, 3 mm error, without being affected by temperature changes, dust, steam, is the leader in similar products;
2, for a wide range, can be used for storage tank area, asphalt storage tank, oil liquefied petroleum gas, reactor, petrochemical industry sewage tank and steel blast furnace molten steel continuous level measurement. But also in the wine, food industry, the pharmaceutical industry and other fields widely used;
3, integrated structure, non-contact speakers;
4, a district, two areas a variety of explosion - proof standard certification;
5, through the user-friendly keys, HART protocol and operating window on the instrument set, programming, advanced multi-function software to eliminate the interference of agitator or other obstacles.
