MODEL P222 SIGNAL PROCESSOR and S256B UV VIEWING HEAD

GENERAL DESCRIPTION:

The IRIS Watchdog III UV 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.
The Ultraviolet sensor is not affected by sunlight and therefore provides reliable flame sensing under a wide range of atmospheric conditions.

S256B VIEWING HEAD

The model S256B viewing head is ground mounted up to 1000 feet from the flare stack tip. The rugged, light weight, all weather aluminum mounting yoke is designed for easy and accurate adjustment of the viewing head. Both vertical and horizontal aiming can be performed, and securely locked once achieved.
Signal strength can be monitored and adjusted at the viewing head location by using the display on the rear of the viewing head.
The electronics are designed with no moving parts to ensure continuous and maintenance-free operation.

P222 SIGNAL PROCESSOR
 

Based upon our flagship flame monitoring system, the IRIS model P522,  the model P222 signal processor uses advanced microprocessor technology for detection and monitoring of Flare Stacks.

 All setup functions and status displays are available from the front panel. The P222 can be powered from 85 to 264 VAC line voltage, or from a DC supply of 22 to 26VDC.

Two independent relays are provided, one giving an early response (adjustable between one and sixty seconds) to a "flame loss" and the other giving a time-delayed response, (adjustable between the early response time and 60 minutes), for a "flame-out" alarm.

The P222 is also compatible with FlameTools software for remote setup and monitoring from a desktop computer system, or a handheld PDA.
