MultiFlame DF-TV7 Optical flame detector

Corriger Prix $0.00

The Oldham Simtronics MultiFlame DF-TV7 optical detector has been designed to detect hydrocarbon fires, while minimizing false alarms. SIL2 or SIL3 certified depending on the model (highest safety level), its very high performance makes it the most efficient detector on the market. Detailed description


The MultiFlame DF-TV7 is fully configurable thanks to the TLU600 portable communication terminal offering great flexibility to the user. The MultiFlame product family offers two configuration types:

  • DF-TV7-T multi-spectrum IR technology
  • DF-TV7-V combined UV and IR technology

MultiFlame DF-TV7-T: Multi-spectrum IR

3 individual wavelengths. The use of three distinct infrared bands and a sophisticated signal processing algorithm provide excellent performance while maintaining an extremely low false alarm rate.

The detector can be supplied with:

  • A standard cartridge, covering the widest range of applications
  • A high sensitivity cartridge for special applications where maximum sensitivity is required

MultiFlame DF-TV7-V: UV + 2 IR combination

The DF-TV7-V is a flame detector that combines a UV sensor and 2 infrared bands. This version is particularly suitable for difficult conditions involving rain, wind, fast light variation, modulations of hot springs or industrial light and other difficult environmental conditions.

The DF-TV7-V can also be configured for special applications, where use in IR or UV alone is required. The UV detector can be sensitive to radiation from electric arcs, x-rays and gamma rays.

TLU 600 remote control

Detector status is visible on the remote control screen, configuration and testing can be performed through this wireless remote control.
