Frequently Asked Questions

What is the Fireye Simplicity 3G-OTH-02853 UV flame scanner used for?

The Fireye Simplicity 3G-OTH-02853 UV flame scanner detects ultraviolet emissions from fossil fuel flames including natural gas, propane, methane, butane, kerosene, and diesel. It is used in industrial burners and boilers to monitor flame presence and provide a flame failure response.

What are the specifications of the Fireye 3G-OTH-02853-1004QD flame scanner?

The Fireye 3G-OTH-02853-1004QD has a four-second flame failure response time, a NEMA 4X (IP66) housing, and provides an analog 4 to 20 mA output referenced to flame signal strength. It operates on 24 VDC with a maximum contact rating of 2 A at 30 VDC or 240 Vac.

Where to buy Fireye flame scanners in Singapore?

3G Electric supplies Fireye Simplicity 3G-OTH-02853 flame scanners to customers in Singapore. We source and deliver these units, handling logistics and customs clearance so you receive the correct model for your application. Contact us for pricing and lead time.

How do you install a Fireye 3G-OTH-02853 flame scanner?

The Fireye 3G-OTH-02853 mounts via a 1-inch NPT female pipe connection (Model 1004) or 1-inch BSP (Model 1004E). It requires clean, dry cooling air at 4 SCFM minimum. Ensure the sight pipe is aligned with the flame and that the scanner's viewing port is unobstructed for reliable detection.

UV90L Series UV Flame Scanners. The UV scanner is ideally suited for gaseous fuels (natural gas & propane). However, it can be used in detecting flames from standard fuel gases, some waste gases and light oil fuels such as No. 2 oil. Flames from heavier oils can be detected with UV scanners but the unburned fuel shroud and/or atomization shroud can block the passage of the UV from the flame zone to the UV tube, causing nuisance burner/boiler trips. Infrared detection is recommended for fuel oil heavier than No. 2, and some installations where waste gases are burned together with natural gas as the main flame
