  1. Sensice ice detectors Dr Ulf Elman, President Sensice 2009

  2. Sensice’s superior detectors Smart new design gives better performance More advantageous price/performance ratio • Significantly reduced maintenance cost Sensice 2009

  3. Traffic accidents in Sweden 1995-1999: • 37828 at snowy or icy road surface conditions, of these did • 15589 occur during black ice conditions, and in addition did • 572 accidents related to aquaplaning occur Sensice 2009

  4. General properties Uses infrared spectroscopy IR reception A IR emission IR reception B Sensice 2009

  5. General properties • Ice transparent to visible light Principles of spectroscopy • Ice is reflective (metal like) in the MIR range • Ice is distinctly ”coloured” in the NIR range Sensice 2009

  6. Applications Use with RWS Sensice 2009

  7. Applications Icing alert at building entrances Sensice 2009

  8. Applications Ice detection at airports Sensice 2009

  9. Applications Ice sheet or icicle buildup at sensitive spots Sensice 2009

  10. General properties Large thickness interval due to two wavelength detection 0.05mm – 3 cm Sensice 2009

  11. General properties 1. Dry 2. Wet Differentiates between six states: 3. Clear ice 4. Snow 5. Sleet 6. Wet clear ice Sensice 2009

  12. Mechanical properties • 182mm x 154mm x 82mm • 3.1 kg Sensice 2009

  13. Optical properties • Recommended range 3-15 m • Use at distances exceeding 25 m impractical Detection range Sensice 2009

  14. Optical properties Angular dependence of detection range Sensice 2009

  15. Optical properties Detection range dependent on surface properties Sensice 2009

  16. Optical properties • Beam divergence 12° Detects over extended area Sensice 2009

  17. Optical properties Lamp exchange port Sensice 2009

  18. Electrical properties • 12V DC Power supply • 2.1A Sensice 2009

  19. Electrical properties • RS232 • 19200 baud, one stop bit and no parity Communication interface • New measurement results every 125 ms Sensice 2009

  20. Electrical properties • Power on LED • Hardware reset Sensice 2009

  21. Electrical properties • Calibration Ports not intended for customer use • Software download Sensice 2009

  22. Resistance to environmental influences Precipitation immunity • Rain shield Sensice 2009

  23. Resistance to environmental influences • 22W heating Dew and frost Sensice 2009

  24. Resistance to environmental influences Temperature range -40°C to +60° Sensice 2009
