(Float Stentc} - <br /> Detector sam ll fr uenc : intermittent Continuous <br /> Evaluation Results <br /> The detector described above was tested for its ability to detect'test liquids In contact v lith the <br /> point sensor. The following parameters were determined: <br /> Detection Accuracy - The measure of sensor response to the presence of ti,quids. <br /> • Response Time -Amount of time the detector must be exposed to liquid before it responds. <br /> Recovery Time-Amount of time that passesbeforethe detector returns to its baselinreading <br /> after the test liquid is removed. <br /> q I <br /> Lower Detection Limit-The smallest liquid concentration that the detector can rellably detect. <br /> Product Activation Height The height of liquid to cause sensor activation. <br /> Specificity Indicates the level of response, of the detector, to several different liquids, <br /> i <br /> 1 Camegle Mellon Research Institute.Test Procediiren for Third Party Fvaluatonof Leak Del <br /> ' Sensor I faukf Gnnfact Leak Detection Systeme: Final Report-November 11, 1991. <br /> Liquid Contact Product Detector- Results Form Palet of 2 <br />
