Product Description Product InformationBGT CE Online RS485 4-20mA Optical Hydroponics Aquaculture Fluorescence DO Sensor Seawater Dissolved Oxygen SensorBGT-WDO(K) integrated on-line fluorescence dissolved oxygen sensor is designed and fabricated based on the quenching principle of excited fluorescence by specific substances in physics. When the excitation light is shone on the fluorescent material on the surface of the fluorescent film head, the fluorescent material is excited and emits fluorescence. The quenching time of fluorescence is affected by the concentration of oxygen molecules on the surface of the fluorescent film head.By detecting the phase difference between fluorescence and excitation light and comparing with the internal calibration curve, the concentration of oxygen molecules can be calculated, and the final value can be output after temperature and salinity compensation. FeaturesSpecificationsNo electrolyte is required and will not be polarized.No oxygen consumption, not affected by flow rate.Built-in temperature sensor, automatic temperature compensation.Free from interference by chemicals such as sulfidesSmall drift, rapid reaction, more accurate measurement.Long service cycle, lower cost of use.Simple replacement of fluorescent cap.Rs-485 interface, Modbus/RTU protocol.Low power consumption,anti-interference.Product ParametersModelBGT-WDO(K)Measuring principle Fluorescence methodRange ability 0~20mg/L (0 ≤ 200% saturation)0~50mg/L customizedResolution ratio0.01mg/L,0.1oCPrecision±2%F.S.,±0.5oCTemperature compensation Automatic temperature compensation(Pt1000)Output modeRS-485 bus, Modbus-RTU protocolWorking conditions0~45oC,<0.2MPaStorage temperature-5~65oCInstallation modeImmersion mountingCable length5 meters, other lengths customizablePower dissipation<0.3W@12VSource12~24VDC ±10%levels of protection IP68 CalibrationTwo-point calibrationFluorescent cap lifeGuaranteed use for one year (under normal use)Sensor shell materialPOM and 316L stainless steel Applicataion Company ProfileOur FactoryFAQQ1: Are you trading company or manufacturer?A: BGT Technology (Beijing) Co., Ltd. is a trading company 100% holding by Beijing Guoxinhuayuan Technology Co., Ltd.
