The IRIS Watchdog Flare Stack Pilot Monitor is an effective replacement or supplement to thermocouples or optical IR systems. It can be connected to an existing ignition system making the replacement of burned out thermocouples effortless. This can be done without plant shut down or flare interruption, saving you valuable time and money.

The IRIS Watchdog electro-optically monitors pilot and flare stack activity using an ultraviolet sensor. It provides continuous burner surveillance indicating the presence or absence of a flame at the flame tip.

Two independent sets of dry contacts are standard, one giving an immediate response to a "flame loss" and the other giving an adjustable time-delayed response for a "flame-out" alarm.

The IRIS Watchdog's viewing head is ground mounted up to 1000 feet from the stack tip. This rugged, light weight, all weather aluminum enclosure is normally secured by a single 3/8" bolt and has a four wire connection. The electronics are designed with no moving parts to ensure continuous and maintenance-free operation. As well, the Watchdog's ultraviolet sensor is not affected by direct sunlight.

Primarily used for monitoring flare stacks in the petrochemical industry, or other applications
where distance and/or accessibility is a factor.
