Honeywell C7024E1001 UV Flame Detector

Features:

• Solid-state electronics provide low power consumption and high reliability.
• The detector can be mounted horizontally, vertically or at any angle in between. Self-checking models require surface alignment and have built-in locating reference points to ensure correct operation of the shutter mechanism.
• The UV sensing tube and quartz viewing window are field-replaceable.
• Threaded conduit fitting and color-coded leadwires allow fast electrical installation.
• Two detectors can be wired in parallel to reduce nuisance shutdowns in applications where the flame is difficult to sight.
• A swivel mount is available to make flame sighting easier.
• Rated to -40°F (-40°C).
• Incorporates a UV sensing tube checking feature, used with the Honeywell R7824C Dynamic Self-Check flame signal amplifier.
• An oscillating shutter interrupts the UV radiation reaching the UV sensor 12 times per minute to provide UV sensor checking. The amplifier circuit components are checked by the microcomputer in the RM7824.
• Protective heat block built into the mounting flange.
• High-pressure quartz viewing window (50 psi [345 kPa]), focusing lens and vibration-resistant mounting accessories available.
