Designed using advanced ultraviolet (UV) and infrared (IR) flame sensing elements, the microcontroller-based FL3110 and FL3111 Flame Detectors are ATEX-approved for use in the European community. They represent the state-of-the-art in secure, reliable and dependable flame monitoring. Highly accurate built-in flicker-discrimination circuitry and self-checking Continuous Optical Path Monitoring (COPM) ensure exceptional fire protection, with freedom from the worry of false alarms. Both feature a segregated Increased Safety wiring compartment whereby the field terminations may be made without exposing the Ex-proof section to the elements. Both the FL3110 and FL3111 feature a wide field of view (FOV), covering a greater area to reduce the number of detectors necessary for flame detection. They are ideal for a wide range of applications within the oil/gas, chemical, automotive and aviation industry. Typical applications include offshore drilling and production platforms, refineries, fuel loading stations, gas pipeline compressor stations, electrostatic paint spray booths and aircraft hangars. The Model FL3110 is an Ultraviolet/Infrared (UV/IR) flame detector designed to detect unwanted fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. The FL3110's electronics are integral within its stainless steel explosion-proof housing, allowing detector information to be processed at the point of detection. The Model FL3111 is an Ultraviolet (UV) flame detector designed to detect unwanted fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. The FL3111's electronics are integral within its stainless steel explosion-proof housing, allowing detector information to be processed at the point of detection. The FL3110 and FL3111 were designed to complement the company's existing FL3112 Flame Detector, which is also designed for the European community with ATEX approval. The Model FL3112 is a Digital Frequency Infrared (DFIR) flame detector designed to detect unwanted fires, and provide alarm outputs directly from the detector while maintaining high false alarm immunity in onshore/offshore applications. It is available with either a stainless steel or bronze (AB2) body, offering a choice for corrosion resistance in offshore applications.
