26GHz radar level gauge

thisThe sensor is26GHigh frequency radar level measuring instrument, capable of measuring up to a maximum distance20Rice. The antenna has been further optimized and processed, and the new fast microprocessor can perform higher speed signal analysis and processing, making the instrument suitable for use in reaction vessels、Solid material siloand someComplex measurement conditions.

principle

The radar level antenna emits narrow microwave pulses, which are transmitted downwards through the antenna.Microwaves that come into contact with the surface of the measured medium are reflected back and received again by the antenna system, send the signalThe transmission to the electronic circuit is automatically converted into a level signal (due to the extremely fast propagation speed of microwaves, the time it takes for electromagnetic waves to reach the target and reflect back to the receiver is almost instantaneous).

The reference surface for measurement is the bottom surface of the thread or the sealing surface of the flange.

Note: When using radar level timing, it is important to ensure that the highest level does not enter the measurement blind zone (as shown in the figure)DThe area shown.

26GRadar level meterfeature：

lSmall antenna size for easy installation；Non contact radar, no wear and tear, no pollution.

lAlmost unaffected by corrosion and foam；Almost unaffected by changes in water vapor, temperature, and pressure in the atmosphere.

lSevere dust environmentFor high-frequency level metersworkThe impact is not significant.

lShorter wavelength, better reflection on tilted solid surfaces.

lSmall beam angle and concentrated energy enhance the echo capability while also facilitating the avoidance of interfering objects.

lThe measurement blind spot is smaller, and it can also achieve good results for measuring small cans.

lHigh signal-to-noise ratio, even in fluctuating conditions, can achieve better performance.

lHigh frequency is the best choice for measuring solids and low dielectric constant media.
