The FL4000H is an advanced multi-spectrum infrared (MSIR) flame detector that provides superior false alarm immunity with the widest field of view. The FL4000H employs a multi-spectral optical IR sensing array with a sophisticated Neural Network Technology (NNT) system to reliably discriminate between actual flames and the vast majority of false alarm sources. The FL4000H detects typical fires such as alcohol, n-heptane, gasoline, jet fuels and hydrocarbons. It can also see through dense smoke produced by diesel, rubber, plastics and lube oil fires.
FL3100H-H2 UV/IR Flame Detector for Hydrogen Applications
The FL3100H-Hydrogen is an Ultraviolet / Infrared flame detector designed specifically to detect hydrogen (H2) fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects H2 fires by monitoring in both the ultraviolet (UV) and infrared (IR) spectral ranges, making it highly immune to false alarms. Configurations with dual Modbus and HART are available. Modbus and HART data can be used for predictive maintenance. The flame detector's electronics are integral within its explosion-proof housing, allowing detector information to be processed at the point of detection.
FL3101H UV Flame Detector
The FL3101H is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet (UV) spectral range for optimized speed of response. Configurations with dual Modbus and HART are available. Modbus and HART data can be used for predictive maintenance. The flame detector's electronics are integral within its explosion-proof housing, allowing detector information to be processed at the point of detection.

Catalytic Bead Sensors
The General Monitors catalytic bead gas sensors are well known for their sensitivity, reliability and longevity and make them the first choice for most users of the catalytic oxidation gas detection principle. Every component is manufactured in-house to ensure optimum performance. Careful matching of the active and reference elements ("beads") result in a sensor that has negligible zero drift with respect to changes in humidity, pressure, and temperature.
