Product Details

The GCL-200W series level sensor is a high-precision frequency-modulated radar level measuring instrument based on the 80GHz millimeter wave as the measurement band, with a maximum measuring distance of 70 meters. The new and fast microprocessor enables higher-speed signal analysis and processing. Advanced multi-target radar signal identification algorithms ensure quick and accurate measurement results in complex working conditions with strong anti-interference capabilities. The optimized structural design allows the instrument to be used for level measurement in high-temperature and high-pressure environments.

This sensor has a built-in Bluetooth parameter adjustment function, allowing for quick on-site debugging via a mobile phone APP. In various measurement scenarios, the non-contact measurement method has significant advantages over traditional pressure, capacitance, and magnetostrictive level measurement devices, such as no pollution, no impact on the measured object, higher measurement accuracy, and easy maintenance. Simultaneously, millimeter-wave radar measurement is not affected by temperature gradients, air pressure, or water vapor, exhibiting good stability and environmental adaptability.
