Spectrex™ 40/40 Series Flame Detectors provide ultrafast, reliable fire detection for hazardous and high-risk industrial environments. Built on advanced multi spectrum sensing technologies—including QuadSense™ IR3 and UV/IR—the 40/40 Series delivers long range flame detection with high immunity to false alarms, helping reduce risk to personnel, assets, and operations.
Rugged stainless-steel construction with heated optics ensures dependable performance in harsh conditions, while continuous self-testing and diagnostics support system uptime and lower maintenance costs. With flexible outputs and digital communications such as HART® and Modbus®, the 40/40 Series integrates easily into new or existing fire and gas systems. Globally certified and backed by a five-year warranty, it is trusted across oil & gas, petrochemical, power, marine, hydrogen, and heavy industrial applications.
The series includes four application specific flame detectors:
40/40D Series
Next generation QuadSense™ platform for maximum coverage and fastest response in high-risk industrial applications requiring long range detection and advanced false alarm immunity.
40/40DI
QuadSense™ IR3 (TripleIR) flame detector ideal for hydrocarbon and hydrogen fire detection in oil & gas, petrochemical, and energy facilities.
40/40DUV
Ultrafast UV/IR flame detector designed for complex fire scenarios where rapid response is critical, such as areas with mixed fuels or high background radiation.
40/40C Series
Compact SharpEye™ flame detectors for space constrained or harsh environments, delivering high performance where size, weight, or mounting flexibility is critical.
