Radar Level Gauge

1. Product introduction of Radar Level Gauge

1. Radar Level Gauge product features

76-81GHz frequency modulated continuous wave (FMCW) radar products, supporting four-wire and two-wire applications. With multiple models, the maximum range of the product can reach 120m and the blind spot can reach 8cm. Because it operates higher frequency and shorter wavelengths, it is especially suitable for solid applications. The working method of transmitting and receiving electromagnetic waves through lenses has unique advantages in high dust and harsh temperature environments (+200℃). The instrument provides flange or thread fixing, making installation convenient and simple.

2. Product advantages of Radar Level Gauge

Based on the self-developed CMOS millimeter-wave RF chip, it realizes a more compact RF architecture, higher signal-to-noise ratio, and smaller blind spots.

5GHz operating bandwidth enables the product to have higher measurement resolution and measurement accuracy.

The narrowest 3° antenna beam angle makes the interference in the installation environment have less impact on the instrument and more convenient to install. The wavelength is shorter and has better reflective properties on solid surfaces, so there is no need for special use of universal flanges for aiming.

Supports remote debugging and remote upgrades, reducing waiting time and improving work efficiency.

3. Radar Level Gauge Communication and Debugging

Instrument debugging can be performed through LCD on site, or the optional upper computer software can be used to debug on the PC side. The radar instrument and the PC communicate through the following methods:

USB to RS485 serial port cable (four-wire system);

USB to TTL serial port cable (two-wire system);

USB to Hart-modem (two-wire system) for communication.

Through Bluetooth debugging on your mobile phone, it makes on-site debugging safer and more convenient.

4G network, remote debugging is carried out through remote modules.
