MONITORING – ILD-X & SGA-1
ECS In-Line Corrosion Detector (ILD-X)
General Description
The ECS In-Line Corrosion Detector is designed to provide an early warning indication of internal corrosion
activity in water-based fire sprinkler systems. The device is designed to be installed where corrosion is
most likely to occur: the air/water interface. A cross-section of the device shows the two key attributes
that allow for early detection of corrosion: an externally milled section of the pipe that creates a
“thin wall” section and a pressure chamber created by an external sleeve welded over the pipe. The thin
wall section of the device will fail before other system piping to provide an early warning indication. The
In-Line Corrosion Detector is equipped with a pressure switch to monitor the pressure chamber. The
In-Line Corrosion Detector can be remotely monitored through a buildings monitoring system.
Installation Instructions
The In-Line Corrosion Detector is manufactured as a spool of piping with roll grooved ends for easy
insertion into the fire sprinkler piping using standard mechanical couplings (supplied by others). All
models of the In-Line Corrosion Detectors are eighteen (18) inches in length. The variety of pipe schedules
and metal are listed in the table under ordering information.
