Level Measurement
Radar Level Transmitter
RD980 (Non-Ex Narrow Beam Angle With 120m Range)
Radar level transmitter RD980 heralds a new era of RADAR LEVEL measurement. Compared to the traditional 6 or 26Ghz meters, the RD980 uses a higher radar frequency of 76-81GHz, with shorter wavelength, smaller beam angle and more concentrated energy.
Features / Benefits
- Higher transmitting frequency of 76-81GHz allows better focusing
- Superior performance in extremely dusty powdered and bulk solid environment
- Long distance measuring range up to 120m
- FFT (Fast Fourier Transform) algorithm increases precision and computational efficiency
- Easy installation due to smaller antenna size
- Performance is unaffected by density, pressure and temperature
- No mechanical moving parts
- 4-20 mA with HART protocol, RS485 option
Applications
RD980 radar level transmitter supports continuous level measurement in powders and solids such as:
- Cement
- Coal
- Iron ore
- Fly ash
- Plastic granular
- Lime slurry
- Pulp & paper
- Corn, soybean, flour
