It combines electro-opticand conductive technologies and can discriminate between hydrocarbons and water. The sensor is compatible with a broad range ofconductive and non-conductive liquids. It is also suitable for high, low or intermediate level detection in practically any tank - large orsmall. Installation is simple and quick through the tank top, bottom or side. With no moving parts, the sensor is ideal for interstitialapplications. The pull ring facilitates easy installation in double-wall tanks and pipes, yet can be removed for use in 1/4" NPT holes.SENSOR OPERATING PRINCIPLESENSOR OPERATING PRINCIPLESENSOR OPERATING PRINCIPLESENSOR OPERATING PRINCIPLESENSOR OPERATING PRINCIPLEThe sensor has the capability of discriminating between conductive and non-conductive liquids, such as water and gasoline. Con-ductivity probes are used in conjunction with an optical prism, consisting of a light-emitting diode and phototransistor. The prismdetects liquid via a loss of light intensity on the phototransistor (due to refraction). The sensor has two outputs: one for conductiveliquid and one for non-conductive liquid. Both outputs are TTL/CMOS compatible.WARNINGWARNINGWARNINGWARNINGWARNINGThe nature of the sensor is that it is a non-voltage producing device, containing limited energy-storing components. However, since itsprimary use is in a hazardous location, an appropriate intrinsically safe interface device must be used and installed in strict accordancewith the National Electrical Code and applicable OMEGA technical brochure and instruction bulletin. Failure to observe this warning couldresult in serious injury or damages.UNPACKINGUNPACKINGUNPACKINGUNPACKINGUNPACKINGRemove the Packing List and verify that you have received all equipment. If you have any questions about the shipment, please callthe OMEGA Customer Service Department at 1-800-622-2378 or (203) 359-1660.When you receive the shipment, inspect the container and equipment for any signs of damage. Note any evidence of rough handlingin transit. Immediately report any damage to the shipping agent.NOTENOTENOTENOTENOTEThe carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removingcontents, save packing material and carton in the event reshipment is necessary.INSTALLATION - Running of Field WireINSTALLATION - Running of Field WireINSTALLATION - Running of Field WireINSTALLATION - Running of Field WireINSTALLATION - Running of Field WireA. The conductors of the intrinsically safe circuit should be sealed in a rigid metal conduit at the point where the wiring enters thehazardous area. The wiring and contacting device should be such that conductive dusts in the area will not close the circuit inplace of the contacts.B. Hazardous area field wiring will store energy due to distributed capacitance and inductance in proportion to its length. Themaximum run of cable has been defined at 750 feet between barrier and sensor.C. Shielded cable is not required, but if used in the application, the shield must be returned to ground. The shield must be con-nected to barrier earth ground.D. Intrinsically safe wiring must be installed in accordance with Article 504 of the NEC, ANSI/NFPA-70 or CEC Part 1, as applicable.All intrinsically safe wiring must have 0.01 inch minimum insulation thickness. Non-intrinsically safe wiring cannot be run inconduit or open raceways together with intrinsically safe wiring.Vmax ≥≥≥≥≥ Voc (barrier)Imax ≥≥≥≥≥ Isc (barrier)Ci + C cable < ( C A barrier)Li + L cable < ( L A barrier)For CSA intrinsic safety approval,For CSA intrinsic safety approval,For CSA intrinsic safety approval,For CSA intrinsic safety approval,For CSA intrinsic safety approval,the following barriers must be used:the following barriers must be used:the following barriers must be used:the following barriers must be used:the following barriers must be used:SBG111950 and SBG111954SBG111950 and SBG111954SBG111950 and SBG111954SBG111950 and SBG111954SBG111950 and SBG111954TerminalTerminalTerminalTerminalTerminalRed/BlackGreen/BlackWhite/BlackU.L.
