Working Principle
The SHR Series Radar Wave Solid / Liquid Level Gauge adopts 80GHz frequency modulated continuous wave (FMCW) radar technology. The radar transmits electromagnetic waves toward the measured medium, and the reflected signal is received and processed to calculate the distance between the sensor and the medium surface. Based on this distance, the instrument realizes continuous level measurement for solids and liquids. Due to its high operating frequency and shorter wavelength, the product provides better focusing ability and stable detection performance, especially in demanding industrial environments.
Technical Characteristics
Based on self-developed CMOS millimeter wave RF chip.
More compact RF architecture with smaller blind area.
5GHz working bandwidth provides high measurement resolution.
Narrow 3° beam angle reduces meter interference.
Shorter wavelength offers better reflection on solid surfaces.
Supports remote debugging to improve working efficiency.
Optional mobile phone Bluetooth debugging is available.
Suitable for dust and harsh high temperature environments.
