kaidi KD-906 26G Radar Level Meter [Anti-corrosion] High Temperature Intelligent

PRODUCT OVERVIEW

The KD-90 series sensors are 26G high frequency radar type level measuring instruments with a measuring range of up to 80 metres. The antenna is further optimised and the new fast microprocessor allows for higher speed signal analysis and processing, making the instruments suitable for use with a wide range of highly corrosive liquids.

THE PRODUCT PRINCIPLE

The radar level antenna emits narrow microwave pulses which are transmitted downwards through the antenna. When the microwave touches the surface of the measured medium, it is reflected back and received again by the antenna system, which transmits the signal to the electronic circuitry and automatically converts it into a level signal (because of the extremely fast propagation of the microwave, the time taken for the electromagnetic wave to reach the target and return to the receiver via reflection is almost instantaneous).

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

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

Note: When using a radar level meter, it is important to ensure that the highest material level does not enter the measurement blind zone (area shown in D in the diagram).

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 vapour, 

temperature and pressure changes in the atmosphere

● Severe dusty environments have little effect on the operation of the HF level meter.

● Shorter wavelengths for 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, which gives good results even for small tanks.

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

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