The certification of discriminating sensors <br />should include functional testing of both water and product detection capabilities. <br />Model BX -PDS, B- F, and -P S: Sensors can only respond to liquid directly in contact with the detection <br />element, and are unable to detect a product release floating on an existing pool of water whose height exceeds the <br />level of the detection element. <br />-PDS <br />Detection time (sec) <br />Fall time (sec) <br />Lower detection limit (cm) <br />BX-PDWF <br />Detection time (sec) <br />Fall time (sec) <br />Lower detection limit (cm) <br />-PD S <br />Detection time (sec) <br />Fall time (sec) <br />Lower detection limit (cm) <br />unleaded gasoline <br />diesel <br />water <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br />0.464 <br />0.468 <br />0.500 <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br />0.63 <br />0.46 <br />0.40 <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br /><1 <br />0.464 <br />0.468 <br />0.500 <br />Specificity Results: <br />Manufacturer claims sensors will respond to any liquid after its threshold is exceeded. <br />No additional materials tested. <br />Manufacturer's Specifications: <br />Manufacturer states that the sensors can also be tested from their location without removal. <br />The test procedure is as follows: When the test button on the controller is pressed, the normally closed light beam is opened, <br />which simulates an actual leak occurrence, sending an alarm signal to the controller. <br />The controller responds to the alarm signal by turning on an audio/visual alarm and printing the test results. <br />http://www.swrcb.ca.gov/ust/leak_prevention/lgl13/vendors/omntec d.shtml 11/28/2011 <br />
