Spectrex 20/20LB Flame Detector

Introduction to Spectrex 20/20LB Flame Detector

The Spectrex Sharp Eye 20/20LB flame detector, equipped with UV (0.185 – 0.260 microns) and IR (2.5-3 microns) sensors, is designed to detect fires involving hydrocarbons, hydroxyls, hydrogen, metals, and inorganic materials. It features three relays (alarm, fault, and auxiliary), 3/4-inch conduit entries, IP66 and IP67 resistance, NEMA 250 6P certification, and an aluminum housing, ensuring exceptional performance.

New Generation: UV/IR Flame Detector Sharp Eye 20/20LB

The UV/IR flame detectors like the Sharp Eye 20/20LB incorporate Built-In Test (BIT) functionality, representing an enhanced version of UV/IR detectors. These models utilize advanced processors and algorithms, providing high sensitivity and improved safety by minimizing unnecessary alarms.

Wide Range of Applications

These advanced flame detectors, backed by successful experience in flame detection technology, have been developed for industrial, military, and commercial applications. Both models are designed to detect fires involving hydrocarbons, hydroxyls, hydrogen, metals, and inorganic materials.

Operating Principles

The UV/IR detector senses energy in the short-wave section of both the ultraviolet and infrared electromagnetic spectra. The UV sensor includes a specific logic circuit to prevent false alarms caused by solar radiation, while the IR sensor is sensitive to radiation in the 2.5 to 3.0 micron range. Signals from both sensors are analyzed for frequency, intensity, and duration, generating an alert signal by simultaneously matching radiant energy in both sensors.
