Product Description

Product Description

The series is FMCW radar operating at 76-81 GHz, which has a maximum measuring range of 120m and a minimum blind zone of 8cm. It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelength make it ideal for solid applications, including those with extreme dust and high temperature to + 200ºC. The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.

Why choose 80 GHz radar level sensor?

Using 80 GHz transmission frequency liquid-level measurement can improve signal focusing to allow accurate, reliable measurement in tanks with agitators, heating coils, and other internal obstructions. That's because a narrower emitted beam makes radar a realistic option for use on ball valves, and increased transmission frequency correlates to a smaller antenna making it ideal for retrofitting and use on smaller tanks.
1. Focused beam avoids obstructions
2. Small antennas take radar where radar has never gone before
3. Enhanced resolution measures to the last drop
When the level of liquid in a vessel gets low enough, 26 GHz radar is unable to distinguish the signal returned by the remaining product from that of the tank bottom, and the user rightly thinks the vessel is empty when it isn't. This is the same as the action-movie computer whiz being unable to enhance surveillance footage. Limited resolution presents a natural handicap to process efficiency. Ultra-focused 80 GHz devices measure liquid down to the last millimeter in the tank, giving users accurate data that can help optimize their processes. It won't thwart a terrorist attack or prevent an elaborate heist, but the enhanced resolution of 80 GHz radar sensors helps users avoid waste.
