ESA / Pyronics UV-2 Flame Detector

The UV2 is a flame detector for industrial use installed in a robust, die-cast aluminium box, equipped with plug in connection and threaded connection for the peepsight. It contains a gas filled UVtube. UV-rays (not daylight or artificial light from discharge or filament lamps) ionise the gas in the tube. The UV2 may be used either with all the electronic systems ESA produces or with any other system provided the tube is operated within its limits.

CAUTIONS AND WARNINGS

• The housing of the photo-tube should be covered. During flame detection the tube itself produces ultra-violet radiation which could be captured by others photo-tubes.
• The detector is also sensible to ultra-violet radiation produced by the crown effect.
• The UV2 is built in accordance with MIL-STD-202F (method 240DO.06" or 10g, 10-500Hz, 15 minutes, 1 cycle) and MIL-STD- 202F (method 213B/100g, 11ms, semiwave, 3 events). A strong mechanical stress (fall) could damage the quartz bulb of the detector, empairing its performances or causing it to be useless. Take care when holding the UV2.
• Humidity within the housing, as well as dust or dirt within the field of vision of the photo-tube could cause losses of signal.
• Use only unipolar cables.
