80GHz Radar Level Transmitter is a range of Frequency Modulated Continuous Wave (FMCW) radar products operating in the 76-81GHz frequency range. These transmitters support both 4-wire and 2-wire applications. The products come in multiple models with a measurement range of up to 120m.
Minimum 3° antenna beam angle, resulting in reduced impact from environmental interferences during installation
Shorter wavelength, providing better reflection characteristics on solid surfaces, significantly reducing dependence on flange orientation.
5GHz working bandwidth, allowing for higher measurement resolution and accuracy.
Supports remote debugging and upgrading, reducing wait times and improving operational efficiency.
Supports Bluetooth debugging via mobile phones, facilitating on-site maintenance by field personnel.
The omnidirectional purging function quickly and effectively cleans the lens surface from dust, frost, and fog, ensuring measurement accuracy.
