Sentry Leak Detection Systems

December 27 2020,

SENTRY is a leak detection system that uses point level technology. The system consists of a non-metallic NEMA 4X enclosure, a green POWER ON pilot light, a red illuminated pushbutton, contact outputs for alarms, and a panel mounted audible alarm. The green POWER ON pilot light will illuminate indicating the system has control power. The leak sensing device is installed in the interstitial space of a double wall tank or at the base of the containment wall. When the sensor detects the presence of liquid, the red illuminated pushbutton will illuminate, the alarm will sound, and the “leak detected” relay will energize. Pressing the red illuminated pushbutton will silence the alarm but the light will remain illuminated. The red illuminated pushbutton will remain illuminated and the “leak detected” relay will remain energized until the leak sensor no longer detects the presence of liquid.
