LRT-1903 Heavy-Dust Radar Level Transmitter

HBRD90X series sensors are 26G high-frequency radar level measuring instruments with a measuring distance of up to 80 meters. The antenna has been further optimized, and the new fast microprocessor can perform higher-speed signal analysis and processing, allowing the instrument to be used for measurement of various highly corrosive liquids.

Product principle THE PRODUCT PRINCIPLE

The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the microwave contacts the surface of the medium to be measured, it is reflected back and is received again by the antenna system, which transmits the signal to the electronic circuit part and automatically converts it into a level signal (because the microwave propagates extremely fast, the time it takes for the electromagnetic wave to reach the target and return to the receiver after reflection is almost instantaneous).

A: Range setting, B: Low adjustment, C: High adjustment, D: Blind zone range

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

Note: When using radar level meter, be sure to ensure that the highest material level does not enter the measurement blind zone (area shown as D in the picture).

Product Features PRODUCT FEATURES

● Compact antenna for easy installation; non-contact radar with no wear or contamination.
● Virtually unaffected by corrosion or foam; nearly immune to atmospheric water vapor, temperature and pressure changes.
● Heavy dust environments have little effect on high-frequency level meter operation.
● Shorter wavelength gives better reflection off inclined solid surfaces.
● Narrow beam angle concentrates energy, strengthening echo performance while avoiding obstructions.
● Smaller blind zone delivers good results even on small tanks.
● High signal-to-noise ratio maintains superior performance even under agitation.
● High frequency, the best choice for measuring solids and low dielectric constant media.
