ARL5200 Series
The ARL5200 Series radar level transmitter leverages advanced Frequency Modulated Continuous Wave (FMCW) technology and intelligent algorithms to deliver unmatched measurement accuracy, reliability, and signal strength. Operating at a high frequency of 80 GHz, it provides superior signal-to-noise ratios, making it ideal for small tanks and fast-filling vessels. This non-contact technology ensures accurate level measurement across liquids, slurries, solids, and dusty environments, unaffected by density, viscosity, temperature, pressure, vapors, or conductivity. With a measuring range of up to 150 m (492 ft) and a high accuracy of ±2 mm, its small beam angle and focused energy enhance anti-interference capabilities, offering stable performance even in challenging applications, including low permittivity media.
