80G Radar Level Gauge Serie

80G Radar Level Gauge Serie

The 76-81GHz frequency-modulated radar level gauge is a non-contact level measurement instrument(NCLM) based on the frequency-modulated continuous wave(FMCW) ,also known as millimeter wave radar(MWR) technology.

It is suitable for continuous level monitoring of liquid slurries, granular materials, powders and solid materials. Its core advantage lies in its extremely strong anti-interference ability, which enables high-precision millimeter-level level measurement in complex working conditions (such as high temperature, high pressure, strong dust, steam or corrosive substances), and is widely used in industries such as petrochemicals, semiconductors, power, metallurgy, food and medicine, and environmental protection. 

Supports communication protocols such as HART and Modbus, and can easily connect to industrial control systems like DCS and SCADA, enabling remote parameter setting, fault diagnosis, and data monitoring. It is an ideal choice for intelligent factories and Industry 4.0.

Product features:

Ultra-high frequency (76-81GHz), with extremely short wavelength (3.7-3.9mm), extremely small beam angle (3° - 8°), strong focusing ability, avoiding interference from the tank wall, suitable for narrow or complex containers. Ultra-high precision: Error ±1mm

Super strong anti-interference ability: Not affected by dust, steam, foam, temperature (-30℃ ~ +200℃) or pressure (vacuum to 1.8MPa).

Debugging: Supports mobile phone Bluetooth debugging, convenient for on-site personnel maintenance.

Installation is flexible and simple: Small in size, light in weight, supports flange or thread installation.

Maintenance: No mechanical moving parts, non-contact measurement, long-term maintenance-free, suitable for harsh working conditions.

Range: The range can reach 120m, blind zone can be 80mm, supports two-wire and four-wire systems.
