JTGB-UF-7609/X Triple Spectral Infrared (IR)) Flame Detectors (Explosion-proof type)
Model JTGB-UF-7609/X Triple spectral infrared (IR)) flame detectors (Explosion-proof type)
JTGB-UF-7609/X
General Description The JTGB-UF-7609/X is a multiple spectral infrared (IR) flame detector which is using three infrared sensors of different wave bands to real-time sampling outside signals. The main sensor responses to the central band of the flame while the reference sensors correspond to the peripheral band. Three sensors that have different response characteristics towards heat sources such as flame, heavy smoke, sunlight and artificial light source provide original foundation of fire behavior judging. Its reliable performance also can distinguish flame at early stage even in complicated environment. It has a preferable immunity of radiation source, for instance, sunlight, artificial light source and other heat elements. The waterproof and explosion-proof design makes JTGB-UF-7609/X suitable for both indoor and outdoor use.

Schematic Diagram
Sensitivity Setup JTGB-UF-7609/X has three sensitivity levels which can be adjusted by user. The original set is in level 2. The correspondence of sensitivity and detecting distance is as follows:
Sensitivity Level level 1 level 2 level 3
Detecting Distance 45m 30m 15m
Testing
Testing fuel
33*33*5cm steel basin
Ethanol(2kg), N-heptane (650g), Gasoline(500g), Diesel(500g)
Level 2 sensitivity (original set) should be used in common operational scene; Level 1 sensitivity should be used in location where requires higher detecting intensity; Level 3 sensitivity should be used in special location where has severe interference. Manual setup: move the dial switch of sensitivity levels and setting. Control panel setup: move the dial switch to 00 and then setup by MODBUS instruction.
