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.
Utilizes self-developed CMOS millimeter-wave RF chips, enabling a more compact RF architecture, higher signal-to-noise ratio, and reduced blind zones. It is unaffected by attenuation caused by steam a
Minimum 3° antenna beam angle, resulting in reduced impact from environmental interferences during installation, making it more suitable for challenging process conditions such as mixing.
Supports remote debugging and upgrading, reducing wait times and improving operational efficiency.
The threaded interface is easy to install and can also be equipped with suitable flanges for different usage scenarios.
Shorter wavelength, providing better reflection characteristics on solid surfaces, significantly reducing dependence on flange orientation.
Supports Bluetooth debugging via mobile phones, facilitating on-site maintenance by field personnel.

HR7380P can be debugged on-site using the LCD display or via PC-based software. Communication between the transmitter and a PC
; can be achieved through the following methods:
USB to RS485 serial cable (4-wire).
USB to TTL serial cable (2-wire).
USB to HART modem (2-wire) for communication.
Bluetooth debugging via mobile phones, ensuring safer and more convenient on-site debugging.
Remote debugging is also possible using the 4G network and a remote module.
