Selection and application summary of radar level gauge

The material level is one of the main measurement parameters in the production process of the cement industry. Unlike other industries, in the cement industry, the material level measurement of solid materials is mainly used, and the liquid level measurement is rare. There are many kinds of solid materials, including block, granular and powder, and the dielectric constant, bulk density, temperature and moisture content of these materials are also different. Contact measurement is the main means of measuring material level in the past, such as capacitive, heavy hammer, tuning fork, resistance rotation, clasp and other measurement methods, because the instrument and the material are in contact during measurement, often appear in the process of use Various problems, such as capacitor hanging material; heavy hammer broken hammer, buried hammer; tuning fork blocking material, etc., and the daily maintenance is very large. By the end of the 20th century, the cement industry began to adopt non-contact level measurement, and the earlier mature non-contact measurement technology has ultrasonic technology. Ultrasonic technology has developed rapidly in recent years and is currently the most widely used non-contact measurement method, especially in liquid level measurement. Ultrasonic level measurement in cement plants has been widely used in raw material deployment warehouses, raw coal warehouses, clinker warehouses, etc., but ultrasonic waves must be transmitted by means of media. Changes in air temperature and humidity will affect the ultrasonic propagation speed, and the dust in the air will also attenuate the ultrasonic propagation signal; the current ultrasonic level measurement is only used to measure bulk or granular materials, and the measurement of the powder bin level. Since the material level surface of the powder bin is very loose during feeding, it has a strong attenuation to the ultrasonic signal, so it is not used now. In the late 1990s, a microwave level gauge with high performance and low price, that is, a radar level gauge, appeared in the field of process detection. The so-called microwave is an electromagnetic wave with a frequency range of 300MHz to 300GHz and a microwave propagation speed of 3x108 m/s. If the frequency is set to 5.8GHz, the wavelength in the atmosphere is about 52mm, its penetrating power is strong, the propagation speed is not affected by dust, steam and medium components, and the propagation attenuation is very small; Dielectric constant ε>In addition to 1.8, the temperature, pressure, density, etc. of the material hardly affect its accurate measurement; the antenna design and shape of the existing radar level gauge ensure the energy of the echo; in addition, the on-site debugging is also very simple, through the special software , can quickly find the correct echo, and immediately convert it into a level value. Due to its superior performance compared to ultrasonic level gauges, in recent years, radar level gauges have entered the market of process testing instruments rapidly and in large quantities, and are widely used in various industries, such as radar level gauges assembled by Zhonghuan Tianyi Siemens. In the cement industry, the field of level measurement is almost occupied by radar level gauges. According to statistics, nearly 90% of the various warehouses and warehouses of large cement plants and grinding stations newly designed in recent years have adopted various types of radar materials. Level gauges such as Siemens radar level gauges have been successfully used in Inner Mongolia Jidong Cement Plant, Beijing Cement Plant and other projects. Radar material level measurement principle and main technical factors Radar material level gauge uses the principle of echo ranging. The transmitting antenna emits microwaves to the measured target, and the microwaves of the measured target are received by the receiving antenna. The signal processor compares the transmitted signal with the received signal, calculates the measured distance, and calculates the corresponding level value.
