Designed for solid and liquid applications, this radar level sensor delivers exceptional accuracy, long measuring range, and stable performance even under dust, condensation, extreme temperature, or low dielectric conditions.
- Uses FMCW (Frequency Modulated Continuous Wave) radar technology.
- Radar emits electromagnetic waves from the top of the tank.
- The reflected signal creates a frequency difference (δf) used to calculate distance.
- Distance formula: R = C × δf / (2 × K)
(C = speed of light, K = frequency modulation slope) Finally converts distance into material level height.
Key Features
