High Temperature UV Unitised Flame detector

Features Benefits Operates at high temperatures (125°C) Suitable for gas turbine applications Wide field of view (110° Horizontal) Greater coverage for detecting fires utilising fewer detectors Continuous Optical Path Monitoring (COPM) Checks optical path integrity and detector’s electronic circuitry once every minute Stainless steel construction High level of corrosion resistance for marine environments Exe wiring compartment Ease of field wiring connection Fast response 100 milliseconds for critical applications Description Applications General Monitors’ Model FL3111HT is a high temperature rated UV-only flame detector designed to detect unwanted fires while maintaining false alarm immunity. The FL3111HT detects in only the ultraviolet (UV) spectral range for optimized speed of response. The detector can withstand ambient temperatures up to 125°C maximum. This is achieved by the use of a specially selected detector and electronic components and very low power consumption to reduce self-heating. The detector’s electronics are integral within an explosion – proof housing, allowing detector information to be processed at the point of detection. The electronics are fully separated from the Exe wire compartment, offering protection during installation and service. The FL3111HT is available with 4-20 mA stepped output. The COPM (Continuous Optical Path Monitoring) self test feature checks the optical path integrity (window cleanliness) and the detector’s electronic circuitry once every minute.
