r <br /> Y <br /> z TANK SE, NTINEL <br /> UNIVERSAL LIQUID SENSOR <br /> DESCRIPTION <br /> The TSP-ULS Liquid Sensor is a low cost point liquid sensor which may <br /> be used with all Tank Sentinel'automatic tank gauge consoles. It may <br /> be installed in sumps,dispenser pans,steel double wall tanks,or other f <br /> locations where the presence of liquid indicates a leak hasoccurred.The <br /> TSP-ULS is based on float-switch technology and is made of chemically @ `> <br /> resistant materials to assure compatibilitywith most liquids.Each sensor a <br /> is supplied with a 25 footcable and is compatible with standard electrical SLC <br /> boxes andfittings.TheTSP-ULS's normallyclosed outputcircuit provides <br /> supervised operation,ensuring thatbroken wires and similar failures will <br /> not go undetected. <br /> APPLICATION —� <br /> The TSP-ULS may be installed in sumps and in interstitial spaces in steel <br /> double wall tanks.A 1l2-inch NPT thread is provided on the compression <br /> gland fitting(cord grip)attached to the sensors cable,allowing it to be THEORY OF OPERATION <br /> suspended from standard electrical boxes and fittings. In typical <br /> applications, the TSP-ULS is screwed into a conduit opening on the The secret to the TSP-ULS'g reliability and low cost is its float switch <br /> bottom of a junction box located on a sump wall.The sensor may be technology.A small magnetically activated reed switch is located inside <br /> positioned vertically by loosening the gland fitting and adjusting the the bodyofthe sensor.Tiinymagnetsarepositioned inside alight weight <br /> length of the cable extending from ft.In steel interstitial tanks the TSP- float which is free to move up and down along the shaft of the TSP-ULS. <br /> ULS is Iowa red into the opening provided on the tank,and is suspended If the sensor is dry,the float hangs down on the shaft so that the magnets <br /> from the optional TSP-K12 installation kit.Many other mounting methods are below the reed switch.When the sensor is immersed in liquid,the <br /> are possible allowing the TSP-ULS to be used in a wide variety of goat rises,and the magnet activates the reed switch.The reed switch <br /> applications and locations. opening is used to indicate whether the sensor is wet or dry. <br /> ORDER PART NUMBER: <br /> WEATHERPROOF <br /> JUNCTBOX 3 <br /> ION .5 <br /> CONDU T <br /> Evaluated for use <br /> -. associated equipment with <br /> _ INCWs U.L fisted <br /> consoles. <br /> TsP-ULs r'a <br /> Distributed by: <br /> #' C'ON] <br /> INTELLIGENT CONTROLS,INC. <br /> P.O.
