UV Flame Monitor System

Industrial power generation gas turbine installations demand the superior protection provided by the Ontic Ultraviolet (UV) Flame Monitor System. The UV Flame Monitor System detects ultraviolet radiation emitted by a hydrocarbon flame and produces an output signal to indicate a flame or no-flame condition.

PROVEN PERFORMANCE

This system has delivered proven performance on General Electric (and GE licensee) gas turbines for more than 40 years.

Land-based and off-shore applications include power generation, pumping stations and shipboard power generation, among other industrial uses. A variety of sensor types, amplifier types, and sensor cable lengths are available.

Design

High sensitivity with fast response time (typical 0.1 second)

Operating distances up to 1,000 feet (305 meters) from Flame Sensor to Amplifier

Amplifiers support multiple voltage requirements: 28 Vdc, 20-35 Vdc, and 115 Vac

Geiger Müller-type sensor phototube detects ultraviolet band at 1800-2600 angstroms

10,000 hours mean time between failures (MTBF)

Two-year shelf life

Features

Flame Sensors available with Factory Mutual (FM) approval for explosive atmospheres

Flame Sensors available with CE mark, ATEX European directive, and IECEx global certification

Explosive Atmosphere 2014/34/EU
