ARL5200 Series
ARL5200 series non-contact radar level transmitter based on Frequency Modulated Continuous Wave (FMCW) technology and smart algorithms to maximize measurement accuracy, reliability and signal strength, and enables it to deliver superior measurement reliability with greater signal-to-noise ratio, even in small tanks and challenging fast-filling vessels. Non-contacting radar technology is ideal for a wide range of applications, and is unaffected by process conditions such as density, viscosity, temperature, pressure, Vapours, Conductivity, etc. Ideal for level measurement in complex applications such as liquids, slurries, solids, particles and dust.
Features
- Unique FMCW radar technology for optimal performance
- High frequency 80 GHz fast-sweep for application flexibility
- Measuring range up to 150 m (492 ft), high accuracy of +/-2 mm
- Non-contact radar, free of wear and pollution
- Anti-interference of noise, vapor, dust, foam, vacuum, etc.
- Small beam angle & focused energy to enhance anti-interference ability
- The measurement of low permittivity constant media is more stable
