Test Results

RBS Rupture Basin Switch (Sumps and Containments)

  Unleaded Gasoline Diesel* Water
Detection time (sec) <5 <5 <5
Fall time (sec) <5 <5 <1
Lower detection limit (in) 1.584 1.522 1.446

*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.

Comments

Control panel: Six intrinsically safe sensor inputs can be used for level indication and/or leak detection. Provides audible and visual alarms.

Sensor: Primarily designed for use with diesel fuel and other distillates but can be used with other fluids - see mfg. for specific limitations.

Detects leakage into day tank rupture basins and double wall piping leak containment systems containing diesel or distillate fuel oils.

Horizontally mounted switch has redundant vapor and fluid sealing provisions, level float operated and magnetically activated.
