RS485 Radar Level Gauge 6m Exia IIC T6 Ga Explosion-Proof
Features of Radar Level Gauge
1. Small beam angle , the energy can be concentrated, enhance the ability of echo and to avoid interference.
2. A shorter wavelength, the reflection of solid surface inclination is better.
3. Good working performance in serious dust solid environment.
4. Smaller measuring blind area,measuring result will be more accurate.

The sound wave is a mechanical wave with a density of 40; gas, liquid and solid 41; propagation depends on the influence of the medium, temperature and pressure on the measurement. Need temperature compensation. Temperature and pressure measurement are generally not applicable. First of all, the ultrasonic level gauge has a temperature limit. Generally speaking, the temperature of the probe cannot exceed 80 degrees, and the propagation speed of sound waves is greatly affected by temperature. Secondly, the ultrasonic level gauge is greatly affected by the pressure, generally within 0.3MPa, because the ultrasonic wave is emitted by the vibration of the piezoelectric material. When the pressure is too high, the sound part will be affected. Third, when the fog or dust in the measurement environment is large, the measurement effect is not good. The radar level gauge emits high-frequency pulses and propagates along the cable. When the pulse is in contact with the material surface, it is reflected by the receiver inside the instrument and the distance signal is converted into a material level signal. The electromagnetic wave is used as the detection signal, which is reflected to the interface as the dielectric constant changes. Electromagnetic waves can propagate in vacuum without being affected by changes in temperature and pressure. Therefore, it can be used in a high temperature and high pressure environment. The measurement of very low dielectric constant media is not applicable. The radar tube uses electromagnetic waves and is not affected by the degree of vacuum. It has a wide range of applications in terms of medium temperature and pressure. The emergence of high-frequency radar tubes makes the application range of radar tubes wider. Therefore, the radar tube is an
ideal choice for level measurement.
