Det-Tronics X2200 UV Flame Detector
Overview
The Det-Tronics X2200 is a single-spectrum ultraviolet (UV) flame detector designed for hazards where speed of response matters more than anything else and where the fuel may not produce a strong infrared signature. Hydrogen, silane and many inorganic or energetic materials burn with weak IR emission but radiate clearly in the ultraviolet, which is why Det-Tronics recommends the Det-Tronics X2200 for hydrogen storage, silane storage, munitions handling and HVDC converter stations. The detector is FM 3260 approved, EN54-10 certified and available in SIL 2 capable versions to IEC 61508, with explosion-proof ratings for both Division and Zone classified locations.
Seven Star LLC supplies the Det-Tronics X2200 to industrial users in Oman and the wider GCC as a trusted supplier, with engineering support in Muscat. As the region builds hydrogen production, ammonia and grid interconnection projects, our team helps engineers decide where a UV detector is the right tool and where a multispectrum IR or UVIR unit will perform better.
Operating Principle
Every flame produces ultraviolet radiation from excited molecules and radicals in the reaction zone. Sunlight at ground level contains almost no energy below about 280 nanometres because the ozone layer absorbs it, so a sensor that responds only in the 185 to 245 nanometre band is effectively solar blind. The Det-Tronics X2200 uses a gas-filled UV tube that converts incoming photons in this band into countable pulses; the processing electronics evaluate pulse rate and duration against the selected sensitivity to decide whether a fire is present. Because UV radiation travels from the flame to the detector at the speed of light and needs no flicker analysis period, response can be extremely quick.
The trade-off with any UV device is susceptibility to non-fire UV sources such as electric arc welding, lightning and x-ray inspection. The Det-Tronics X2200 addresses this with advanced signal processing and an arc rejection mode, and it continues to respond correctly in the presence of modulated blackbody radiation from heaters, ovens and turbines. The specification sheet shows a one square foot n-heptane fire detected at 85 feet (25.9 m) in about 3 seconds and a 32 inch methane plume at 100 feet (30.5 m) in about 2 seconds in very high sensitivity, low arc mode, and models are available that meet the NFPA 33 requirement for response in under 0.5 seconds.
Engineering Design of the Det-Tronics X2200
The Det-Tronics X2200 shares the robust X-Series housing used across the Det-Tronics flame detector range: copper-free painted aluminium or cast 316 stainless steel, IP66/IP67 and NEMA 4X sealing, 3/4 inch NPT or M25 conduit entries and an integral wiring compartment. Flameproof Ex db IIC and increased safety Ex db eb IIC models are certified under ATEX and IECEx with T6 to T5 temperature classes, while FM and CSA approvals cover Class I Division 1 Groups B, C and D. Microprocessor-heated optics help the window stay free of moisture and ice.
Three Det-Tronics X2200 sensing versions are offered. The standard X2200 includes a small Krypton-85 source inside the UV tube for automatic Optical Integrity verification, the X2200G omits the radioactive source, and the X2200M uses a molybdenum element with an extended 185 to 265 nanometre range that is better suited to sulfur fires, some black powders and other unusual chemistries. Automatic, magnetic and manual oi testing, a replaceable oi plate and a tri-colour status LED make routine proof testing straightforward from ground level.
Key Features
The main design points of the Det-Tronics X2200 are summarised below:
- Solar-blind UV sensing in the 185 to 245 nanometre band gives fast response to hydrocarbon, hydrogen and silane flames.
- Arc rejection and advanced signal processing reduce alarms caused by electric arcs and other transient UV sources.
- Optional NFPA 33 compliant models respond in under 0.5 seconds for high speed protection.
- With an Eagle Quantum Premier system and high speed deluge module, a correctly configured installation can meet NFPA 15 ultra-high-speed requirements.
- Fire, fault and auxiliary relays are fitted as standard, with contacts rated 5 A at 30 Vdc.
- An optional 0–20 mA output with HART and an RS-485 Modbus link support integration with PLC and DCS systems.
- Pulse output models make it simple to replace older Det-Tronics UV detectors on existing controller based systems.
- Low power consumption of 2.5 W at 24 Vdc nominal eases power supply and cable sizing on large detector loops.
Industrial Applications
The specification sheet names hydrogen storage, munitions, silane storage and HVDC converter stations as typical applications. In Oman these hazards appear in green hydrogen and ammonia pilot plants planned around Duqm and Salalah, hydrogen-cooled generator areas and electrolyser rooms in power stations, semiconductor and solar module facilities that handle silane, explosives magazines serving the mining and quarrying sector, and converter halls on high voltage grid interconnections. Indoor process rooms with little background UV are also a good fit for the Det-Tronics X2200, because its fast response limits fire growth before suppression is released.
Where welding, lightning or strong reflections are a concern, engineers often specify the Det-Tronics X2200 inside enclosures and use UVIR or multispectrum IR detectors on outdoor plant. Seven Star LLC supplies the Det-Tronics X2200 and the wider X-Series range from Muscat, including mounting arms, air shields and oi plates, and our engineers can support detector layout reviews for projects across Oman and the GCC.

Where Det-Tronics equipment is used
These detectors are designed for hazardous locations in harsh industrial settings. The manufacturer describes its fire and gas systems and its flame and gas detectors as SIL 2 capable and certified by third-party approval bodies. Typical sites in the GCC are oil and gas production facilities, gas plants, tank farms and turbine enclosures, where a detector has to be matched to the fuel and to the layout of the protected area.Ordering Det-Tronics detectors: what we need
Det-Tronics detectors are ordered by a matrix part number that fixes the housing material, thread size, output type and approval. Send the complete part number from the detector label, not only X3301 or PIRECL. If you are replacing a unit in an existing system, tell us whether it is wired by relay, 4-20 mA or on the EQP network, because the output board differs. Add the serial number and a nameplate photo, and list the accessories you need, such as swivel mounts, air shields or a calibration kit for gas detectors.Browse Det-Tronics products by category: Fire & Gas Detector.
