The C7024 Flame Detector series are 24Vdc solid-state electronic devices for sensing the ultraviolet radiation emitted during combustion of most carbon-containing fuels such as natural gas, LP gas, and oil.
• Solid-state electronic circuitry provides low power consumption and high reliability.
• Detectors can be mounted horizontally, vertically or at any angle. The self-checking models require faceplate alignment and have integral locating reference points to assure proper operation of the shutter mechanism.
• Ultraviolet radiation sensing tube and quartz viewing window are field replaceable.
• Threaded conduit fitting and color-coded lead wires allow rapid electrical installation.
• Two flame detectors can be wired in parallel to reduce nuisance shutdowns in difficult flame sighting applications.
• Incorporates UV sensor tube checking feature used with Honeywell dynamic self-check R7824C Flame Signal Amplifiers.
• Oscillating shutter interrupts ultraviolet radiation reaching UV sensor 12 times per minute to provide the UV sensor checking function. Amplifier circuitry components are checked from the microprocessor in the RM7824.
• A swivel mount is available to facilitate flame sighting.
• Models are available with a -40°F (-40°C) rating.
• C7024E: Housing meets NEMA 4 enclosure standards (indoor, outdoor protection: rain-tight, dust-tight, hose directed water). ï Protective heat block built into the mounting flange. High pressure (50 psi [345 kPa]) quartz viewing window, focusing lens and anti-vibration mounting accessories available.
• C7024F: Housing designed to be explosion-proof and Underwriters Laboratories Inc. Component Recognized for use in hazardous locations: Class 1, groups C and D, and Class 2, groups E, F and G. Viewing window rated for 100 psi (690 kPa).
