The 7155-0001 Ultra Violet Detector is a photo-sensitive flame sensor for use with the Pyronics Sens-A-Flame II and ESTRO flame monitoring system. The detector tube has a peak spectral response in the short wave ultra-violet region and, therfore, will not be activated by visable light, infra-red energy or sunlight, ect.
The detector responds to the ultraviolet radiation generated by all flames. The detector electronics have been designed to be compatible with the standard Sens-AFlame II and ESTRO systems. The system may be used with either 7150, 7155 Detectors of Flame Rods without modification. Both Detectors and Flame Rods may be used intermixed on the same installation. Dual sensing means UV detectors and/or Flame Rods may be used on any flame input terminal.
The 7155-0001 Purge Air Nipple provides a 1/8" inlet for a supply of cool air to control the temperature of the detector. The air also helps keep dirt and moisture out of the sighting port. The purge air nipple is threaded on both sides and is installed between the burner port and the detector
