5.5.2 ESPLUCINeo – „LUMINANCE METER LUCI NEO“ EN
Information
  • Sensor for the luminance of the tunnel environment
  • Image support of the proven analog sensor
  • Measurement method: Integral luminance according to CIE-L20 or RABT (EABT) / DIN 67524
  • Long-term stable amplifier, high reliability
  • Vario optics for field-of-view adjustment
  • Precise adaptation to the spectral sensitivity of the human eye, V(λ)
  • Electronically controlled heating to prevent icing
  • The front glass is effectively protected against contamination by a special aperture ring using the air stagnation effect
  • Fault message output via potential-free contact for collective notification in case of temperature/signal error
  • Up to two separate measurement channels with individual measurement ranges (e.g. 0…1,000 and 0…10,000 cd/m²)
Advantages
Remote control of the sensor’s alignment, ensuring traffic safety and energy efficiency
  • Detection of measurement interference sources (also remotely during operation via software)
  • On-site adjustable field of view, allowing local adaptations
  • Optimal adaptation of the sensor to the driver’s perspective, increasing safety
  • LAN and WLAN connection for data transmission
  • Video image accessible from all current operating systems via standard web browser
