1.2 DF-TV7-T: multi-spectrum IR
The DF-TV7-T is a multi-spectrum flame detector using
three individual infrared wavelengths. The use of three
different IR bands and a unique signal processing
algorithm allows excellent flame detection performances,
while offering a very low rate of false alarms.
The detector can be supplied with a configurable
cartridge:
•
A "standard range" sensor cartridge covering most applications
•
A “high sensitivity" sensor cartridge for special applications where the maximum sensitivity
is required.
1.3 DF-TV7-V: combined UV and IR
Designed to cover a large detection range while ensuring excellent immunity against false alarms,
the DF-TV7-V is the alternative when multi-spectrum IR cannot be used.
False alarms are minimized using two infrared wavelengths plus a fast-acting UV wavelength to
confirm detection. This version is useful in difficult environmental conditions, such as combined
rain and wind, rapid sunshine variations, hot sources modulations, industrial lighting etc.
The DF-TV7-V is also configurable for special applications,
where using just dual IR or just direct UV detection is
required.
The UV detector can be sensitive to UV welding radiation or
lightning, X rays and gamma rays.
1.4 Technical specifications
Each detector is constructed as follows:
•
A wall-mounted support secured by three screws and including cable gland (M20)
(optional). There are 2 standard entries and an optional one.
•
A stainless steel (316L) explosion-proof housing containing a set of tropicalized electronic
cards
•
The sensor cartridge contains the flame detection circuitry. So, it is possible to change the
cartridge easily. The multi-spectrum IR detector is also available in a high sensitivity
version.
•
An IR communication head is located below the detector housing. It is used for
communication with the maintenance hand-held terminal (TLU).
•
A metallic support cable (optional) connects the wall mounting support and the housing,
making the maintenance easier.
