SensorexPRODUCT INSTRUCTION SHEETDissolved Oxygen Sensor Care and Use InstructionsProduct InstructionsIntroductionYour Sensorex Dissolved Oxygen(DO)sensor is a galvanicFIG.1#3#2Cable Shrinkelectrochemical device;i.e.it does not require power fromyour meter or controller to generate its signal.The DO sensorwill provide a millivolt signal proportional to the concentrationof oxygen in the water(model DO6400,DO6400TC)or 4-20mAcurrent output(models DO6441 and DO6442).Your Dissolved Oxygen sensor consists of an cathode,anode,Part NumberShrink Colors#1#2#3and an electrolyte separated from your process fluid by an oxy-D06400N/ANAgen permeable membrane.The oxygen passing through theD07400whiteNAN/Amembrane reacts at the cathode,giving up electrons,whichD06441vellowN/AD06442greenyellowN/Aproduces an electrical current.See FIG1 for sensor ID.D07441yellowwhiteN/AD07442greenyellowwhiteElectrical ConnectionsDO6400 and DO6400TC models:Red wire of Sensor to DO input+(cathode)Black wire of Sensor to DO input-(anode)White and Green wires of Sensor to Temperature input(see wiring FIG 2.)D06441,D06441TC,D06442,D06442 TC models:Red wire of Sensor to DO input+(cathode)Black wire of Sensor to DO input-(anode)(see wiring FIG 3.White and Green wires of Sensor to TemperatureF1G.2Getting Your DO Sensor Ready to UseYour DO sensor is shipped to you dry and is not ready for use.Seesteps #1,#7,#8,#9 and #10 of the"Sensor Reconditioning"section of this sheet for instructions on sensor preparation.The installed membrane shipped with the probe is usable if itDCOLORFUNCTIONpasses the leak test in step #8.Maintenance items includedwith your sensor include:1 each membrane lock tool,2 eachREDCATHODEPTFE or HDPE membranes,2 each membrane o-rings andBBLACKANODEWHITETEMPERATURE250mL of electrolyte.GGREENTEMPERATURECalibrationFirst,ensure that the sensor is properly connected to theinstrumentation circuitry.A visual display must be available toF1G.3Power Supplyread the sensor output.For sensors that have been installed⑧sensor red wirein service,gently wipe the membrane using a soft cloth tosensorremove accumulated biological debris.The Probe may beblack wirecalibrated in air,or in air-saturated water.Please calibrate outof direct sunlight,which may effect accurate calibration.Thesimplest method is to calibrate in air.To calibrate in air,turnthe probe,so that the membrane is facing upward.Place aPLC DVMdrop of clean water on the membrane.If calibrating in airsaturated water,ensure that the water is saturated,by agitat-ing the water sample.Place the probe just below the surface ofthe water level.Parts covered by this product data sheet include:D06400,D06400TC,D06441,D06442,D06441TCD06442TCPage 1 of 7Form:InstrD06400 [Rev:2012-10-26]2011 Sensorex Corportion
