Flame detectors are available in 2 styles. A general purpose one which responds only to UV, and a combined UV and IR detector. The combined detector gives a higher immunity to false alarms caused by spurious UV sources, and is also available in explosion proof enclosure.
The development of the ZTFD101 ultra violet flame detector is
based on over 10 years experience in the field of flame detection.
The ZTFD101 is particularly suited in applications where flame can
be expected to develop initially rather than smoke, due to the
nature of the combustible materials such as camera films,
video/audio/computer tapes , and petrochemical products (such as
oil or petrol).
The detector should be installed indoors, either on a ceiling or a
wall. For maximum sensitivity the detector should see the side of the
flame, but this is not always possible. Also avoid obstructions
(including glass), as the detector is a line of sight device.
Calculate the area of coverage of each device based on the height
(or distance from risk area if wall mounted) and the cone of vision (120?).
This detector works best when fed from a clean supply with
Maintenance consists of ensuring the quartz sensor tube is kept
clean and free from silicon, oil and grease. The detector should be
functionally tested at regular intervals.
Please note that this detector can give false alarms if exposed to
spurious sources of UV, such as sparks, uncovered quarts halogen
lights, or lightning.
? Low profile shape for UV detector
? The detector is solar blind and incorporates an electronic filter to
eliminate unwanted alarms from naturally occurring phenomena.
? High immunity to Electrical noise & RF Interference.
? Fast response time.
? Supplied with its own base.
? Typically detects 25mm gas flame at 6 metres within 3 seconds.
? 120o cone of vision.
? Low Cost.
? CE Marked.
