The OMNTEC BX -series product - <br />distinguishing sensors employ proven <br />optic technology for leak detection <br />coupled with the principle of conduc- <br />tivity to distinguish between product <br />and water. An internal microprocessor <br />enables the BX -series sensors to be <br />self-diagnostic and self -identifying. <br />Each sensor can recognize its serial <br />number, part number and function. <br />This allows the controller to differenti- <br />ate one sensor from another on the <br />network and relay critical information <br />HAS Cable Length <br />12 Feet <br />General Purpose Sensor <br />The BX -PDS was designed to <br />accommodate a variety of applica- 3/4" NPT NIPPLE <br />tions. With its convenient size and <br />ability to detect liquids at any <br />angle, the BX -PDS sensor is the <br />ideal sensor for sumps, dispenser pans and containment areas. IIH-31 <br />F t -w -I <br />Diameter <br />MAWS <br />Sensor for Double -Wall Steel Tanks & <br />Xerxes 4' -Diameter Dry Double -Wall Fiberglass Tanks <br />The BX-PDWS was designed to <br />fit into the annular space of <br />steel double-wall tanks. It can <br />distinguish liquid hydrocarbons <br />from water, and, like all BX -series <br />sensors, can be remotely <br />tested without removal. <br />Cable Length <br />20 Feet <br />3/4" <br />Strain\ <br />Relief <br />3/4" NPT NIPPLE <br />3" <br />I� <br />Diameter <br />UAW <br />Sensor for Dry Double -Wall Fiberglass Tanks <br />The BX-PDWF was designed to fit into <br />the annular space of dry double-wall <br />Cable length <br />fiberglass tanks. It can distinguish liq- <br />ta• <br />20 feet <br />uid hydrocarbons from water, and, like <br />all BX -series sensors, can be remotely <br />tested without removal. With its slim, <br />Sized to tank <br />compact shape and flexible snake -like <br />diameter <br />shaft, the BX-PDWF can easily be <br />installed and removed from grade. <br />(When ordering, the part number will <br />denote tank diameter.) <br />1-5/8" <br />5/e" <br />Principles of Operation <br />for BX -PDS and BX-PDWS <br />Ism <br />Bright Eye <br />Microprocessor <br />LED <br />Detector <br />am <br />Prism Conductivity <br />Dry condition Electrode <br />OEM <br />Electrical <br />Conductance <br />----- <br />I f_ I <br />I <br />Wet Condition <br />Principles of Operation <br />for BX-PDWF <br />LED <br />Bright EyeDetector <br />Microprocessor <br />LED Conductivity <br />Prism Electrode <br />Dry condition <br />Electrical <br />Conductance <br />------ -- <br />7 <br />—J -J <br />Wet Condition <br />
