CAN ROBO

THE UNIT MEASURES AIRSPEED BY COMPARING THE TEMPERATURE DIFFERENCE BETWEEN A SENSOR EXPOSED TO THE AIR AND ONE IN A CHAMBER.

The Can Robo is a compact, robust Air Velocity Robot that us spaced regularly in underground roadways to indicate a go/no go air velocity indication for the passing traffic. The unit works on a temperature differential to determine the airspeed by comparing the difference between two sensors, one in the air ( visual probe) and one in the chamber.

These units work from a 220V supply and have battery backup for power down situations
The thermister probe is housed in a removable jack plug  for easy repair and calibration,. This means only the probe, and the entire unit must not be remove.
The total Equipment does not have to be sent to the surface ,as the jack containing the electronics can be sent out for repair and calibration by itself.
As air flow over the probe or thermistor, the temperature drops, and the unit, once reaching m/s, goes Green. When the LED turns Red that is the indication for the vehicle to stop.

  • Easy to install
  • Cosy effective
  • Fixed position in the underground Roadways
  • More Accurate
  • Removable jack plug for easy repair and calibration
  • Only the Probes need to be calibrated, not the whole unit.
  • Unit is compact and robust
  • proven durability in the operational area
  • unit is splash-proof
  • easy to install
  • LED Display colour- Green above m/s- Red under m/s
  • High visibility display ( L.E.D.S)
  • 220Vac supply
  • Battery backup- 6 Hours
  • Probe is housed in a removable jack-plug for ease of repair and calibration
