ATVUK-PMR-G
Guided Wave Radar Level Transmitter is a reliable and highly accurate instrument designed for continuous level measurement of liquids, slurries, and bulk solids. Utilizing Time Domain Reflectometry (TDR) technology, this transmitter guides low-frequency radar pulses along a probe, ensuring precise measurement even in challenging process conditions. Operating at a frequency of 1.8GHz, it is especially well-suited for applications involving low dielectric materials, foaming surfaces, or turbulent environments where traditional radar systems may struggle. Guided Wave Radar Level Transmitter offers dependable level measurement where traditional sensors may fall short, delivering accuracy and peace of mind in demanding industrial processes.
The Principle Behind Guide wave radar level transmitter
The working principle of the 1.8GHz guide wave radar level transmitter involves the transmission of microwave signals towards the surface of the measured material. These signals travel along a guide wave and reflect back when they reach the surface. The time taken for the signals to return is measured, and based on this time, the level of the material can be calculated. This method is favored for its robust performance in various size and shape tanks, as well as for various materials.
