HR7380P Typical 80 GHz Radar Level Transmitter

HR7380P Typical 80 GHz Radar Level Transmitter

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.

1. Introduction

2. Advantages

※ 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 and dust, and can provide stable measurements even for materials with weak reflection characteristics or low dielectric constants.

※ 5GHz working bandwidth, allowing for higher measurement resolution and accuracy.

※ Minimum 3° antenna beam angle, resulting in reduced impact from environmental interference during installation, making it more suitable for challenging process conditions such as mixing.

※ Shorter wavelength, providing better reflection characteristics on solid surfaces, significantly reducing dependence on flange orientation.

※ 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 threaded interface is easy to install and can also be equipped with suitable flanges for different usage scenarios.

3. Communication and debugging

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.
