It may <br /> be installed in sumps,dispenser pans,steel double wail tanks,or other <br /> locations where the presence of liquid indicates a leak has occurred.The <br /> TSP-ULS Is based on float-switch technology and is made of chemically <br /> resistant materials to assure compatibility with most liquids.Each sensor <br /> is supplied with a 25 foot cable and is compatible with standard electrical <br /> boxes and fittings.The TSP-ULS's normally closed output circuit provides <br /> supervised operation,ensuring that broken wires and similar failures will <br /> not go undetected. <br /> APPLICATION <br /> The TSP-ULS maybe installed in sumps and in interstitial spaces in steel <br /> double wail tanks.A 1/2-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's reliability and low cast is its float switch <br /> bottom of a junction box located on a sump wail.The sensor may be 'ethnology.A small magnetically activated reed switch is located inside <br /> _ ihe body of the sensor.Tiny magnets are positioned inside a light weight <br /> positioned vertically by loosening the gland filling and adjusting the <br /> • length of the cable extending from it.In steel interstitial tanks the TSP- float which is tree to move up and down along the shaft of the TSP•ULS. <br /> ULS is lowered into the opening provided on the tank,and is suspended if the sensor is dry,the float hangs down on the shalt so that the magnets <br /> fromtheoptionalTSP-Kl2installationkit.Manyothermountingmethods are below the reed switch.When the sensor is immersed in liquid,the <br /> are possible allowing the TSP-lAS to be used in a wide variety of float rises.and the magnet activates the reed switch.The rand switch <br /> opening is used to indicate whether the sensor is wet or dry. <br /> applications and locations. <br /> ORDER PART NUMBER: <br /> WEATHERPROOF 3.5 <br /> JUNCTION 90X - <br /> CONDUIT Evaluated for use as <br /> associated equipment with <br /> INCON's U-L,listed <br /> consoles. <br /> t,m <br /> TSP-tr <br /> Distributed by; <br /> CLJ.\U <br /> INTELL-IGENT CONTROI_S,INC. <br /> P.0,Isax 638.Sam,ME 04072 USA <br /> 800-833-8328/201-283-0156 <br /> O(X)-1254 Rev.c Fax:207-283-0158 <br />
