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.
