New fl ame detector delivers superior performance for optimal fi re safety
Plant managers and other personnel responsible for fi re safety at oil refi neries, chemical plants, or other industrial facilities will fi nd the new General Monitors FL500 UV/IR Flame Detectorfrom MSA offers relentless protection to safeguard people, equipment and facilities.
The next-generation FL500 optical fl ame detector is FM performance approved for six different fuel sources: butane, ethane, heptane, methane, methanol and propane. By combining a precision ultraviolet (UV) sensor for quick response with an infrared (IR) sensor that monitors fl ame-emitted radiation, the FL500 fl ame detector operates at faster speeds with unsurpassed false alarm immunity to provide the industry’s most reliable monitoring in its class.
The FL500 detector offers a wide fi eld of view up to 130° for optimum protection. It features three external LED indicators for local verifi cation by technicians of normal operation, fault conditions and alarms. On-board relays provide fl exible detector status communications with automated plant safety and control systems via HART, Modbus, 4-20 mA sink or source communications.
Designed with continuous optical path monitoring (COPM), the exceptionally dependable FL500 fl ame detector conducts its own self-check every two minutes. These optical and electrical self-check diagnostic routines ensure the sensor’s optical path is clear and that the detector’s sophisticated electronic circuitry is operational for true operator peace-of-mind.
The FL500 detector also can be tested with the explosion proof TL105 Test Lamp, which simulates the fl ickering of a fi re and provides a high-energy, broadband radiation source that emits energy in both the ultraviolet and infrared spectra to safely activate the fl ame sensors. The TL105 Test Lamp allows the detector to be tested under real fi re conditions without the associated risk of an open fl ame.
With its new and improved design, the FL500 UV/IR fl ame detector offers a reduced footprint and simplifi ed wiring to make it easy-to-install and maintain. Its rugged 316 stainless steel housing measures a compact 4.5-inches (114 mm) in diameter by 5.5-inches (140 mm) in length and weighs only 9 pounds (4.0 kg).
The FL500 provides fi re safety monitoring in the most demanding environments around the globe--from the heat of the Middle East to the frigid regions of Northern Europe and Canada. The operating temperature range is: -67°F (-55°C) to 185°F (85°C) with a relative humidity range of 0 to 95% RH, non-condensing.
addition to FM performance approval, other global approvals include: CSA, ATEX, IECEx, EN 54- 10 and CE Marking. The next-generation FL500 UV/IR Flame Detector represents the true future of fl ame monitoring performance, reliability, fl exibility and value.

Broadband infrared sources for tomorrow’s refrigerant leak detection
The need to monitor refrigerant leaks is widening because of the variety of applications and increasingly stringent environmental regulations. Despite the trend for transition towards refrigerants with low-Global Warming Potential (GWP) and low- Ozone Depleting Potential (ODP), gas leakages need to be detected. Axetris’ EMIRS Infrared Sources provide reliable results.
Following the ban of Hydrochlorofl uorocarbons (HCFCs) due to their extremely high ODP in the 1990s, Hydrofl uorocarbons (HFCs) were widely used. With their extremely high GWP, also they are not the refrigerant of choice in the long term. Potential candidates could be Hydrocarbons, NH3
or CO2
. These substances may not be
harmful in terms of ODP and GWP but they are fl ammable, explosive, poisonous or at least hazardous to health.
When building new cooling systems, the most important factors next to economical considerations are safety and environmental friendliness. It does not matter whether we look at commercial racks and condensing units > 5 kW, industrial refrigeration facilities > 1 MW or commercial A/C systems > 20 kW, the fact remains that all those units need to be maintained and monitored to detect leakages soon enough to minimize the environmental impact and secure safety. Optical gas sensors are the ideal technology to detect small leakages reliably, due to their high sensitivity and long-term stability.
The Axetris broadband EMIRS technology with its unique black body characteristics offers an excellent product for such optical gas sensors. It is suitable to measure almost all species of refrigerants by covering the complete MIR range making it the best choice for modular NDIR refrigerant gas leak sensors.
The EMIRS200 IR Source is established for very precise built-in refrigerant leak detectors. The new EMIRS50 IR Source family is optimised for portable and battery operated refrigerant leak detectors or simple refrigerant sniffers.
