The unit is positioned vertically on the bottom of the tank annulus or at maximum fuel level of a tank to prevent overflow. The all-polysulfone level switch features a single pole, single - throw contact, actuated -by the float of the unit. The contact status is annun- ciated on the X76S monitor. The HVA is a miniature liquid sensor f tricted vertical riser tS-3 oruse m res applications. Listed 48RO Model LS -7 Tarek Level Sensor The Model LS -7 Level Switch is designed for horizontal applications where access is difficult, such as a dual -wall fiberglass tank's annulus. The unit Is engi- neered to provide high -reliability point -level sensing. The plastic construction is compatible with all hydrocar- bon liquids, providing long, trouble-free performance. UL Listed 48RO Models LS -3 N.O. &LS -30 Hydrostatic LeakDetectors The Models LS -3 N.O. and LS -30 Leak Detectors monitor any U.L. rated hydrostatic double-wall fiberglass tank reservoir. Due to the possibility of groundwater seeping into a reservoir, the LS -30 is de- signed to detect liquid level gains as well as losses. LS -10 and LS -20 Reservoir Assemblies are supplied when a permanent reservoir is not part of the tank package. UL Lasted 48RO uD Listed 48Ro ` r,>s;3 intrinsically Safe Power Supply Sensor Alarm Modules intrinsically Safe Barriers Field Wiring Compartment Power Input Terminals Model JT -2 Tank Leak Sensor The Model JT -2 assembly consists of a pressure switch, fill valve and safety release valve. The Model JT 2P Positive Pressure Leak Sensor is designed to provide monitoring of the annular cavity of double-wall tanks via air pressure. Any breach of the containment will cause a pressure loss and will be .* sensed by the pressure switch trans- figuring its contact should pressure fall below .5 PSIG. The Model JT -2V Vacuum Leak Sensor monitors for loss of vacuum and will be sensed by the vacuum switch trans- ferring its contact should vacuum fall to .5 inches of mercury.
