Oldham Simtronics SG50-F-IR3-V-AS24 Triple IR (IR3) SG50-F for Hydrocarbon Fire where exhaust gases may

What is the Oldham Simtronics SG50-F-IR3-V-AS24?

The Oldham Simtronics SG50-F-IR3-V-AS24 is: Triple IR (IR3) SG50-F for Hydrocarbon Fire where exhaust gases may be present, with Near Ir camera, HART, SIL2, 3/4NPT. The Spyglass SG50-F family covers a wide variety of fire types in a stainless steel housing, and is offered in triple infrared (IR3) and ultraviolet with infrared (UV-IR) technologies, including versions for hydrogen and other alternate energy fuel fires. An on-board video option lets a fire be viewed in real time or reviewed after an incident without anyone being at the scene. An ultra fast detection mode is available for spark and NFPA 33 applications, and the family covers arcs and sparks in windmills, munitions, and hot engine exhaust such as helipads.

What are the specifications of the Spyglass SG50-F Flame Detectors?

• Detection technologies: triple infrared (IR3) and ultraviolet with infrared (UV-IR), plus hydrogen fire versions
• Field of view: 90 degrees horizontal, 80 degrees vertical
• SG50-F-UV-IR detection time: 5 ms for a fast fire burst or explosion, 1 s for a 0.1 m2 n-heptane pan fire at 0 to 15 m, under 2 s at 15 to 30 m
• SG50-F-UV-IR-F detection time: 5 ms for a fast fire burst or explosion, 1.5 s for a 0.1 m2 n-heptane pan fire at 0 to 15 m, under 3 s at 15 to 30 m
• Adjustable time delay 0 to 30 seconds, with automatic and manual built-in test
• Operating voltage 24 V DC nominal (18 to 32 V DC); 120 mA standby, 180 mA maximum with all systems including the window heater
• Outputs: 0-20 mA, HART, Modbus and 3 relays
• Cable entries: two conduit entries, 3/4 inch NPT or M25 x 1.5, one plugged with a certified stopper
• Explosion proof approvals: ATEX, UKCA, IECEx, PESO, INMETRO, FM and FMC; performance to ANSI FM 3260 and EN 54-10
• Functional safety: certified SIL 2 per IEC 61508

What should you check before ordering?

Response figures here are test results against a defined fire, not marketing rounding: a 0.1 m2 n-heptane pan fire, measured at two distance bands. That matters when comparing the two UV-IR variants, because the F version is consistently the slower of the pair on the same fire (1.5 s against 1 s at 0 to 15 m, and under 3 s against under 2 s at 15 to 30 m), while both hit 5 ms on a fast burst or explosion. The temperature ceiling also moves with the temperature class ordered: T5 approval runs to 75 C ambient while T4 runs to 85 C, so the class chosen on the order limits where the detector can be mounted.

How do the part numbers differ?

Part numbers separate the detection technology (UV-IR or IR3, with H2 versions for hydrogen), the presence of HART and SIL 2, NFPA 33 compliance, and the cable entry thread (M25 or 3/4 inch NPT), so two references that look alike can differ on approval scope rather than on the sensor.

Where is it used?

Typical service: Hydrocarbon fire detection in process and storage areas; Hydrogen and alternate energy fuel fires; Arc and spark detection, including windmills and NFPA 33 spray application areas; Munitions handling and storage; Helipads and other areas with hot engine exhaust; Incident review where the on-board video option is fitted.

How do I order or get a quote?

PE Energy supplies the Oldham Simtronics SG50-F-IR3-V-AS24 on a quote basis: send the part number with your application details and we return pricing and lead time. Fixed gas and flame detection is quoted rather than listed because most references ship configured for target gas, range, approval scope and cable entry, and those choices are fixed at the part number. This part belongs to the same product line as the Spyglass SG50-F flame detector line already in our catalogue.
