NYRD-PB 26G Planar Antenna PTFE Measuring Range 0-40m Flat Type
26G NYRD-PB Radar Working Principle
The radar horizontal antenna emits narrow microwave pulses, which are transmitted downward through the antenna. When the pulse wave touches the surface of the medium under test, it is reflected back and received again by the antenna system. This signal is transmitted to the electronic circuit section and automatically converted into a horizontal signal (due to the extremely fast propagation speed of the pulse, the time required for the electromagnetic wave to reach the target and return to the receiver after reflection is almost instantaneous).

26G NYRD-PB Radar Design Features
Small antenna size for easy installation; no contact with radar, no wear and contamination
Virtually no corrosion and blistering; unaffected by changes in average density, temperature and pressure
The heavy dust environment has little effect on the operation of the HF level meter.
The shorter the wavelength, the better the reflection on an inclined solid surface.
Small fast angle and concentrated energy not only improve the return capability, but also help to prevent interference.
Small measurement blind area, good results can be obtained when measuring small tanks.
Even with fluctuations, high signal-to-noise ratio can achieve better results.
High frequency is the best choice for measuring solids and low dielectric constant environment.
