Honeywell C7012E1112/U UV detector 120VAC self-check

Honeywell C7012E1112B flame sensors are electronic devices that use semiconductor electronics to detect ultraviolet radiation that occurs during the combustion of various carbon-containing fuels, such as natural gas, liquefied petroleum gas and petroleum.

Basic properties

– The semiconductor circuit provides high energy efficiency and reliability of the device.

– Models based on semiconductor technology replace previous models based on vacuum cathode ray tubes.

– Sensors can be installed at various angles to the surface: horizontally, vertically and in other ways.

– Replacement of defective parts, such as a cathode ray tube for detecting ultraviolet radiation and a quartz viewing window, is carried out at the place of operation.

– The use of threaded connections of color-coded conductors facilitates and accelerates the installation of equipment.

– To reduce the probability of accidental disconnection in difficult flame monitoring conditions, it is possible to connect two sensors in parallel.

– There are models designed to work at low temperatures, up to -40 °C.

– The devices are used with flame signal amplifiers with dynamic self-monitoring by Resideo (R7247C, R7747C, R7847C).

– The vibrating gate interrupts the ultraviolet radiation on the ultraviolet radiation sensor, providing control of the cathode ray sensor tube. The components of the amplifiers are checked by the microprocessor of the regulators of the BCS 7700 or 7800 SERIES.

– Some models comply with BGC (England) and DIN (Germany) standards.

– The housing complies with NEMA 4 standards provided for protection against moisture and dust. A protective heat block is built into the mounting flange.

– The possibility of installing quartz viewing windows with high pressure, focusing lenses, hinged supports and anti-vibration accessories.

Features include

– Compatible with R7247C, R7747C and R7847C amplifiers.

– Voltage and frequency variations.

– Power consumption up to 7.0 watts.

– Operating temperatures inside the case from 40° C to 79°C.

– Storage temperature from 51°C to 79°C.

Periodic maintenance includes cleaning the viewing window, checking and adjusting the detection system according to the recommendations of the burner manufacturer, as well as replacing the necessary components to maintain proper operation of the system.

The replacement parts include various elements, such as electronic tubes for detecting ultraviolet radiation and viewing windows, as well as a mechanism consisting of a gate valve and a coil.
