compact, gas tight ultra-violet flame sensing head giving rectification compatible output. Tested and approved by BG plc, the unit is specifically designed to operate with all Pactrol burner controls in applications where probe detection is not feasible.

Description

The UV head gives a rectification compatible output enabling all Pactrol Gas Burners to be operated on either flame rectification (electrode) sensing or ultra-violet flame sensing without any modification to the Pactrol control.

Construction

The Ultra-violet sensing head and associated circuitry is housed in a robust gas tight aluminium housing. The viewing end of the housing is protected by a 2mm thick quartz window.

The Ultra-violet sensing head is designed to be attached to the viewing tube or burner by means of a 1/2" BSP thread. Electrical connections are made through a 4 pin plug and socket, simplifying installation and replacement.

The printed circuit board mounted voltage-multiplier enables the UV flame sensing head to be operated consistently over a wide range of mains voltages.

Voltage: 110-120V - 50/60 Hz
