The certification of <br />discriminating sensors should include functional testing of both water and product detection <br />capabilities. <br />Model 794380-343: This sensor can only respond to liquid directly in contact with the detection <br />element, and is unable to detect a product release floating on an existing pool of water whose <br />height exceeds the level of the detection element. <br />unleaded gasoline diesel water <br />Micro Sensor 794380-344 <br />Detection time (min) <1 <1 <1 <br />Fall time (min) <1 <1 <1 <br />Lower detection limit (in) <0.1 <0.1 <0.1 <br />Specificity Results: <br />Both 794380-343 and 794380-344 sensors are reported to respond to any liquid after the sensor threshold <br />is exceeded. <br />Sensor 794380-343 is designed to discriminate between product and water. Separate alarms are <br />designed to be triggered for product and water. <br />Manufacturer's Specifications: <br />http://www.swrcb.ca.gov/cwpliome/ustileak prevention/lgl13/Vendor .../veeder root_u.htm 7/29/2004 <br />unleaded gasoline <br />diesel <br />water <br />Discriminating Interstitial Sensor <br />794380-343 <br />Detection time (min) <br /><1 <br /><1 <br /><1 <br />Fall time (min) <br /><1 <br /><1 <br /><1 <br />Lower detection limit (in) <br /><0.1 <br /><0.1 <br /><0.1 <br />unleaded gasoline diesel water <br />Micro Sensor 794380-344 <br />Detection time (min) <1 <1 <1 <br />Fall time (min) <1 <1 <1 <br />Lower detection limit (in) <0.1 <0.1 <0.1 <br />Specificity Results: <br />Both 794380-343 and 794380-344 sensors are reported to respond to any liquid after the sensor threshold <br />is exceeded. <br />Sensor 794380-343 is designed to discriminate between product and water.
