PRODUCT OVERVIEW

kaidi KD series sensors are 26G high frequency radar type level measuring instruments with a measuring distance of up to 80 meters. The antenna is further optimized and the new fast microprocessor allows for higher speed signal analysis and processing, making the instrument available for measurement of a variety of highly corrosive liquids.

THE PRODUCT PRINCIPLE

The radar level antenna emits narrow microwave pulses, which are transmitted downward by the antenna. Microwave contact with the measured medium surface is reflected back again by the antenna system, the signal will be transmitted to the electronic circuit part automatically converted into a level signal (because the microwave propagation speed is very fast, electromagnetic waves to reach the target and return to the receiver by the reflection of the time used in this round trip is almost instantaneous).

                                                                                                                                               A: range setting, B: low level adjustment, C: high level adjustment, D: blind range

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

Note: When using the radar level meter, make sure that the highest material level cannot enter the measurement blind zone (the area shown in D in the figure).

PRODUCT FEATURES

● Small antenna size for easy installation; non-contact radar, no wear and tear, no contamination.

● Virtually unaffected by corrosion, foam; virtually unaffected by water vapor, temperature and pressure changes in the atmosphere.

● Severe dusty environment has little effect on the work of high frequency level meter.

● Shorter wavelength, better reflection on inclined solid surfaces.

● Smaller beam angle and concentrated energy, which enhances the return capability and helps to avoid interfering objects at the same time.

● Smaller measurement blind spot, and good results for small tank measurements.

● High signal-to-noise ratio for better performance even under fluctuating conditions.

● High frequency, a better choice for measuring solids and low dielectric constant media
