FD-410EX Fog Detector

FD-410EX Fog Detector

Ideal for: offshore platforms and drilling rigs

The FD-410EX Fog Detector is a Zone 1 rated microprocessor device designed to automatically detect and execute the control functions for a fog signal, or other devices, when visibility has decreased below a pre-programmed level.

The Fog Detector is programmed to transmit a beam of modulated infrared light every 2 minutes; it measures the amount of light reflected by the atmosphere to the receiver in the instrument.


  • Pulsed infrared, backscatter, single station type
  • Microprocessor-based design ensures maximum reliability and minimum maintenance
  • Automatic self-checking; electronic pilot light system automatically compensates for fouling/fogging of the lens automatic self-test feature
  • Remote on/off control terminals
  • Requires no warm-up period; heaters for windowpanes are not required
  • Extremely low power consumption; ideal for solar power applications
  • Remote monitoring of fault and visibility levels
