The ESA Pyronics 74903 is a UV-2 Flame Detector with 10673 3/4" CHLG-2 Support.  This flame detector is used in combination with Shutter SHR for burner operation applications. 

The flame detector is divided into 4 parts:  

  • Electric connection plug
  • Housing
  • Athermic connection with quartz glass and gaskets
  • Cooling Air Connection

The flame detector has a 3/4" thread to connect to the Shutter SHR die-cast aluminum body.  In the UV tube section, it is filled with gas that will be ionized by the UV-rays.  Applicable to other ESA electronic systems.  When ESA UV-2 Flame Detector is in used, it must be operated within its range. 

The UV-2 flame detector should be handled with care and you need to take note of the hazards.  Remember to cover the photo-tube housing for the reason that it produces UV radiation during flame detection which can be captured by other photo-tubes.  Also, be cautious in handling and prevent falling that may damage the detector quartz bulb.  Consistently check and clean the photo-tube to prevent dust or dirt accumulation which can affect the signal. Only unipolar cables can be used.
