TG-EL-D4A Fuel Sentry Control Unit, HD-A2-C Optical Discriminating Sensor
INTERSTITIAL DETECTOR (LIQUID-PHASE)
Provides audible and visual alarms.
Sensor: Primarily designed for use with diesel fuel and other distillates but can be used with other fluids - see manufacturer for specific limitations.
*This evaluation determined the sensors' responses to the liquids shown above. Biodiesel blends B6-B20 meeting ASTM D7467 and biodiesel B100 meeting ASTM D6751 would also produce an alarm if the sensor threshold is exceeded. Responses to these fuels were not determined, but would be expected to be very similar to the diesel responses.
Used to detect the presence of liquids in fiberglass and steel tank annular spaces or the presence of liquids in tank vault spaces.
Can also be used for detection of leaks into sumps or other containment vessels used to collect liquids.
