UV QRA4.U Flame Detector for supervision of gas flames, yellow or blue oilflames and for ignition spark proving.

Operation:
When the UV radiation of the flame in the position of the detector is high enough, the detector is activated during each half wave, giving a signal current. With this type of flame supervision, the UV radiation emitted by gas or oil flames is used to generate the flame signal.

Specifications:

- UV flame detector for frontal illumination.

- For direct mounting on the burner.

- Intermittent use.

- Housing made of aluminium, with ¾“-14NPSM connecting thread for fitting the detector to the burner or boiler. Connecting wires of about 1.8 m length for the electrical connection.

- ½“ - 14NPSM thread for a fitting, required for the connection of a Menzel tube for protecting the connecting wires (½“ conduit)

- Temperature Range: -20 to 60 °C.
