Industrial Flame Detector - Model 3100

A 4-20 mA version of the Model 3100 Flame Detector is also available.

Self-diagnostic features of the microprocessor continuously perform system tests, watching for any faults, which would impair its ability to accurately detect a flame and declare an alarm. The systems being checked include input power, sensor circuits, relay circuits and several other internal systems. The Model 3100 also performs a through-the-lens test of the sensor and lens systems.

The microprocessor in the Model 3100 is programmed with state-of-the-art fire algorithms and continuously analyzes the data from the sensor array for individual intensity values, change of intensity values, relationship of intensity values, and frequency signature correlation. The Enhanced Relay Models also include a second alarm relay available for alarm verification purposes. The verification level is field selectable.

The Sierra Monitor Model 3100 Series Flame Detector utilizes Ultraviolet, Infrared and Visible spectrum to provide continuous and reliable flame detection. Flame detectors incorporating just IR or just UV can experience false alarms. Even some IR/UV detectors can experience false alarms. But the Model 3100 tri-spectra design provides enhanced false alarm rejection This tri-spectra design also gives the Model 3100 the ability to detect flames from both hydrocarbon and non-hydrocarbon sources, making it the ideal product for typical chemical/petrochemical plants where the flame source could be from a variety of gases.
