Honeywell C7012A1145 Rilevatore di fiamma a raggi UV 120V

Honeywell C7012A1145 flame detectors are semiconductor electronic devices for detecting ultraviolet radiation emitted during the combustion of most carbon-containing fuels, such as natural gas, liquefied petroleum gas and petroleum. Features • The semiconductor electronics circuit provides low power consumption and high reliability. ü Semiconductor models directly replace the previous models operating on the principle of a vacuum cathode ray tube. • Detectors can be mounted horizontally, vertically or at any other angle to the surface. • Replacement of the failed cathode ray tube for detecting ultraviolet radiation and quartz viewing window is carried out directly at the place of operation. • The speed of installation of electronic equipment is ensured by the threaded connections of the conductors and their color coding. • Two detectors can be connected in parallel to reduce the probability of an erroneous shutdown under difficult flame observation conditions. • The hinged support provides convenience when observing the flame. • There are models with a nominal value of -40°C. • Designed for joint use with Resideo C7012A1145U safe combustion devices using flame signal amplifiers based on rectification (R7247A, R7289A, R7747A, R7847A1082) and Ampli-Check rectification (R7247B, R7747B, R7847B1072) manufactured by Honeywell. Gorenje • C7012G models meet the requirements of BGC (England) and DIN (Germany) standards. • The housing complies with NEMA 4 standards provided for housing elements (protection inside and outside the room: water-, dust-proof, protected from direct ingress of water). • A protective heat block is built into the mounting flange. Specifications 1. For use in flame retardant systems of rectification type. 2. Voltage and frequency: Individual models at 100, 120, 208, or 240 V, all at 50/60 Hz. 3.
