Honeywell Purple Peeper Flame Sensor C7024 Series

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).

• Use with R7824C Dynamic Self-Check Flame Signal Amplifier. • Circuitry provides low power consumption and high reliability. • Mount horizontally, vertically or at any angle in between. • Field-replaceable UV radiation sensing tube and quartz viewing window. • Quick electrical installation with threaded conduit fitting and color-coded leadwires. • Reduce nuisance shutdowns by wiring two in parallel. • Oscillating shutter interrupts UV radiation using the R7824C amplifier. • C7024E meets NEMA 4 standards with viewing window rated to 20 psi. • C7024F has an explosion-proof housing for use in hazardous atmospheres with a viewing window rated to 100 psi.
