Honeywell C7024E1001 UV flame detector 24VDC
Flame detectors C7024E1001/U 24 V are solid-state electronic devices for measuring ultraviolet radiation emitted during the combustion of most carbon-containing fuels, such as natural gas, liquefied gas and oil. Features • Solid-state electronic circuit ensures low power consumption and high reliability. • Detectors can be installed horizontally, vertically or at any intermediate angle. Self-monitoring models require alignment of the front panel and have built-in control points to ensure proper operation of the device. • The tube for measuring ultraviolet radiation and the quartz viewing window are replaced in the field. • Threaded pipe and color-coded lead wires ensure quick installation of electrical equipment. • Two flame sensors can be connected in parallel to reduce the number of emergency shutdowns in complex flame detection systems. • There is a swivel mount to facilitate the observation of the flame. • Temperature -40° F (-40°C). • Enables the UV sensor tube test function used in Honeywell R7824C devices. • The oscillating shutter interrupts the UV radiation by accessing the UV sensor 12 times per minute to provide the UV sensor check function. • The housing complies with NEMA 4 standards (indoor and outdoor protection: waterproof, dustproof, water supply from a hose). • Protective heat block built into the mounting flange. • High pressure (50 psi [345 kPa]) Quartz viewing window, focusing lens and anti-vibration mounting accessories are available. Specifications Flame detector: For use with dynamic self-monitoring R7824C amplifier. Voltage: 24 V DC. Power consumption: maximum 7.8 watts. Rated ambient temperature (outside the enclosure): -20°F to +175°F (-29°C to +79°C). Nominal storage temperature: -60°F to +175°F (-51°C to +79°C). Nominal pressure of the quartz viewing window: 20 psi ([138 kPa). A focusing lens (20 psi [138 kPa] nominal) or a high pressure viewing window (50 psi [345 kPa] nominal) is available. Mounting: Mounting flange with 3/4-inch NPT internal thread for mounting to the inspection tube. Electrical connections: NEC Class 1 color-coded lead wires, 8 feet (2.4 meters) long. Number of lead wires: 6. Threaded lead wire hole in the front panel: 1/2-14 NPSM or 7/8-20 UNSM internal thread for fixing the pipeline. Weight: Approximately 4.25 lbs (1.9 kg). Easy maintenance: Replaceable viewing windows in the field and a tube for measuring ultraviolet radiation, a self-monitoring coil and a shutter assembly.
