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 "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 by the use of 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.
