The certification of discriminating <br /> sensors should include functional testing of both water and product detection capabilities. <br /> Model 794380-322 and 794380-352: Currently the SWRCB UST Program staff discourages the use of polymer <br /> strip discriminating sensors at new installations in California. This is due to concerns about the impact that <br /> repeated/prolonged exposure to hydrocarbons may have on the sensor's ability to alarm and recover from <br /> alarm reliably. Since current evaluation protocols do not address this issue, no new polymer strip sensors <br /> should be installed until new evaluation protocols are in place. <br /> pol mmer_strip float switch <br /> unleaded gasoline diesel water <br /> Discriminating Dispenser Pan <br /> Sensor 794380-322 high* low* <br /> Response time (sec) —10 min 2-12 hrs <1 <1 <br /> Recovery time (sec) N/A** N/A <1 <1 <br /> Lower detection limit - height (in) N/D** N/D 7.66 1.37 <br /> Lower detection limit - thickness (in) 0.005 0.005 N/A N/A <br /> Discriminating Containment Sump <br /> Sensor 794380-352 <br /> Response time (sec) —10 min 2-12 hrs <1 <1 <br /> Recovery time (sec) N/A N/A <1 <1 <br /> Lower detection limit - height (in) N/D N/D 12.28 1.35 <br /> Lower detection limit - thickness (in) 0.005 0.005 N/A N/A <br /> *The "high" and "low" refer to high and low level alarm points of float switch sensors. <br /> ** See glossary. <br /> Specificity Results (in addition to above): <br /> Activated: synthetic gasoline, jet-A fuel, n-hexane, toluene, xylene(s) <br /> http://www.swrcb.ca.gov/past/leak_prevention/lgl13Nendor Files/veeder root_o.html 9/9/2004 <br />
