Red Jacket Electronics RE400-179-5 to RE400-199-5 Combination High Level/Low Level Sensor,
RE400-042-5 Hydrostatic Sensor,
Red Jacket PPM 4000 with Optical Liquid Discrimination Sensor

INTERSTITIAL DETECTOR (LIQUID-PHASE) 

Detector:

Output type:

qualitative

Sampling frequency:

continuous

Operating principle:

float switch (RE400-179-5 to RE400-199-5 Combination High Level/Low level sensor, RE400-042-5 Hydrostatic Sensor), optical sensor (Red Jacket PPM 4000 with Optical Liquid Discrimination Sensor)

Test Results:
*California requires annual certification of all leak detection equipment. The certification of discriminating sensors should include functional testing of both water and product detection capabilities.

Model PPM 4000 with Optical Liquid Discrimination Sensor: This sensor can only respond to liquid directly in contact with the detection element, and is unable to detect a product release floating on an existing pool of water whose height exceeds the level of the detection element.

*Evaluations determined these 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.

**See glossary

Specificity:
Evaluator claims RE400-179-5 to RE400-199-5 Combination High Level/Low Level Sensor and RE400-042-5 Hydrostatic Sensor will respond to any liquid once threshold has been exceeded.

Comments:
RE400-179-5 to RE400-199-5 Combination High Level/Low Level Sensor model numbers and high level detection limit vary with length of sensor.
PPM 4000 with Optical Liquid Discrimination Sensor evaluation lists all PPM, RLM, and ST models, including the Multiplexer Unit.  However, evaluation procedures were performed using model PPM 4000.
Sensors are reusable.
