High frequency radar liquid (object) level gaugeYK-RD9

Suitable Medium

Liquid, solid

Unsuitable Media

gas

The 90X series sensor is a 26G high frequency radar type level measuring instrument, with a maximum measuring distance of up to 80 meters. The antenna is further optimized, and the new and fast microprocessor can perform higher-speed signal analysis and processing, making the meter can be used for some complex measurement conditions such as reactors and solid silos.

Principle

The high-frequency microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), and encounters the measured medium. Due to the sudden change of the dielectric constant, reflection is caused, and a part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

Features

     1. The antenna is small in size and easy to install; non-contact radar, no wear and no pollution.


     2. It is hardly affected by corrosion and foam; hardly affected by water vapor, temperature and pressure changes in the atmosphere.


     3. The severe dust environment has little effect on the work of the high-frequency level meter.


     4. The wavelength is shorter, and the reflection on the inclined solid surface is better.


     5. The beam angle is small and the energy is concentrated, which enhances the echo ability and at the same time helps to avoid interference.


     6. The measurement blind area is smaller, and good results can be obtained for small tank measurement.


     7. High signal-to-noise ratio, better performance can be obtained even in fluctuating conditions.


     8. High frequency is a good choice for measuring solid and low dielectric constant medium.
