CS140 Background Luminance Sensor

The CS140 is a high-quality background luminance sensor. It provides the luminance data required to assess the visibility range for lights such as runway lights or warning lights.

The field of view and elevation angle follow aviation practice, and the spectral response follows the CIE curve that matches the typical response of the human eye.

The CS140 meets the standards required for Runway Visual Range, as well as the standards of ICAO, the UK CAA and the FAA. (This includes CAP670 and CAP746.)

 

Benefits and Features

  • Monitoring of internal supply voltages and temperatures
  • Elevated field of view with hood horizontal to give high resistance to contamination on the window
  • RS-232/RS-485 outputs so can operate independent of a host visibility sensor for flexible, reliable operation
  • Automatic window contamination detection
  • Configurable window contamination correction
  • High-performance sensor at a competitive price
  • Incorporates automatic dew and hood heaters for all-weather operation
  • Low power consumption; suitable for solar-power applications
