Flame detector UV model 40/40U, 4040UB
The new 40/40 UV Flame Detector detects hydrocarbon-based fuel and gas fires, invisible hydrogen flames, and fires from hydrides, ammonia, silane and other organics. The 40/40U-UB is the most durable and weather resistant UV flame detector currently on the market. Its new features include a heated window to eliminate condensation and icing; HART capabilities, for digital communications; lower power requirements; and a compact, lighter design.
Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and is SIL2 (TUV) approved to IEC 61508.
The model 40/40UB includes a Built-in-Test (BIT) feature, whereas the 40/40U model does not.
Note: This type of detector should not be exposed to UV radiation sources such as welding, sparks, and electric arcs as it will cause false alarms.
