Product Description

The Fireye 3G-OTH-02792 flame sensor is designed to sense flame in extreme high pressure and hot environments such as those found on turbine generators in power generation facilities. Similar challenging environments can be found near steam boilers, waste incinerators, down-fired reformer furnaces, ground flares, rotary kiln systems, ovens and dryers in power generation facilities, oil refineries, petrochemical, ammonia plants, paper and pulp industries.

Frequently Asked Questions

What is the Fireye 3G-OTH-02792 flame sensor used for?

The Fireye 3G-OTH-02792 flame sensor is designed to detect flame in extreme high-pressure and high-temperature environments, such as gas turbine generators in power plants, steam boilers, waste incinerators, down-fired reformer furnaces, ground flares, rotary kilns, and industrial ovens in refineries, petrochemical, ammonia, and pulp industries.

What are the specifications of the Fireye 3G-OTH-02792 flame sensor?

The Fireye 3G-OTH-02792 VFS-2000 flame sensor features a stainless steel 304 housing, 3/4" male NPT mounting, operating temperature up to 325 °C at the hot end, 4-20 mA DC output, UV solid-state sensor with silicon carbide diode, spectral range 200-400 nm, and approvals including CE, Ex, UL SIL 3, and UKCA.

Where to buy the Fireye 3G-OTH-02792 flame sensor in Singapore?

You can source the Fireye 3G-OTH-02792 flame sensor through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this industrial flame sensor for harsh environments.

How to install the Fireye 3G-OTH-02792 flame sensor?

The Fireye 3G-OTH-02792 flame sensor mounts directly to the turbine using a 3/4" female NPT standard pipe connection. No tuning or HART setup is required—it is ready to use out of the box. Ensure the sapphire window at the combustor is clean and the fiber optic cable is properly routed to avoid damage.
