溶解氧仪使用方法

溶解氧标定溶解氧标定必须在已知氧浓度的环境中进行。

YSI 550A溶氧仪可用mg／L或％饱和度来标定。

以下是这两种方式的标定步骤。

标定前要准确标定YSI 550A，你需要知道以下资料：1．被测水样的大概盐度。

新鲜淡水的盐度大约为零,海水盐度约为35ppt。

如果你不知水样的盐度，可以用YSI 30盐度一电导一温度仪来测得盐度值。

2．对于在％饱和度模式下标定，需要知道你所处位置的海拔高度(英尺)。

这些资料可从互联网或者当地机场或气象台获得。

如果要从米转化到英尺，除以0．3048要得到最佳结果：1．每次使用前都标定仪器，以防止漂移。

溶解氧读数取决于标定。

2．在与样品温度相差不超过±1 0℃范围内进行校正。

用％饱和度标定：1．确定仪器标定室内的海绵是湿润的。

把探头插入标定室。

2．打开仪器，等待约15—20分钟，让仪器预热及读数稳定。

3．同时按下并释放上箭头和下箭头键，进入标定菜单。

4．按下Mode键直至“％”作为氧气单位出现在屏幕右侧。

然后按下ENTER。

5．LCD屏幕上会提示你输入以百英尺为单位的当地海拔高度。

用箭头键增加或碱少输入的海拔高度，当正确的海拔高度出现在LCD上时，按下ENTER键。

例如：输入数字12代表1200英尺。

6．CAL将显示在屏幕左下角，右下端则显示校正值，主显示栏则显示DO读数(标定前)。

一旦当前溶解氧读数稳定，按下ENTER键。

7 ．LCD将提示你输入被测水样的近似盐度，输入0至70(ppt)数字。

用箭头键可增加或减少盐度设定数字。

当LCD显示正确盐度时按ENTER键。

仪器将返回至正常操作状态。

用MG／L来标定1．打开仪器，等待约15—20分钟，让仪器预热及读数稳定。

2 将探头放入已知ｍg／L渎数的溶液，在整个标定过程中以最少1／2英尺每秒(16厘米每秒)的频率在水样中持续搅拌或晃动探头。

3．同时按下并释放上箭头和下箭头键，进入标定菜单。

4．按下Mode键直至“mg／L”作为氧气单位出现在屏幕右侧。

ABB 光学溶解氧传感器应用说明书

—A B B M E A SU R EM ENT & A N A LY TI C S | A PPLI C ATI O N NOTEThe advantages of optical dissolved oxygen sensors Optimize your aeration process using ABB’s optical DO systemSave energy and cut operatingcosts using ABB’s opticalDO system.Measurement made easy—IntroductionA typical wastewater treatment plant uses four main stages of treatment – Primary, Secondary, Tertiary and Sludge.The secondary treatment stage is the point at which organic waste is oxidized to form carbon dioxide, water and nitrogen compounds. To achieve this, most modern plants use an activated sludge system, which uses a culture of bacteria and other organisms to feed on the organic materials inthe sewage.Dissolved oxygen is a crucial ingredient in the efficient digestion of organic material during the biological stage of the wastewater treatment. In the correct concentration and under the correct temperature conditions, dissolved oxygen helps to encourage the effective propagation of bacteria and other organisms in waste water, which then feed on the sewage waste, converting it into carbon dioxide, water and energy.In many cases, the energy needed to power the equipment used to aerate secondary treatment processes can account for well over half of a plant’s total energy costs.The applicationThe oxygen needed for the aeration process is provided in one of two ways. Mechanical or surface aeration uses pumps or agitators on the surface of the tanks. The rate of aeration is controlled either by varying the speed and depth of the agitator, or the speed of the pump.In contrast, the diffusion method uses perforated pipes or domes in the base of the aeration tanks. The supply of oxygen is varied by changing the speed of the compressors which force air through the diffusers.In either case, accurate control of dissolved oxygen levels is critical to ensure the optimum conditions for the digestion process. If levels are too low, then the bacteria growth will be reduced, affecting the rate of sewage breakdown. If levels are too high, energy costs can increase, and the effectiveness of the sensor can be impaired by the formation of slime. For this reason, the recommended optimum level for dissolved oxygen is generally set at between 1.5 and 2 ppm.The challengeConventional techniques used to measure dissolved oxygen, such as electrochemical or galvanic diffusion methods, have traditionally struggled tomaintain accurate measurement over long periods of time without frequent recalibration due to sensor drift.Drawbacks such as limited membrane life havemade it difficult to achieve long-term accuracy and reliability. Moreover, the need for electrochemical sensors to be inspected, serviced and recalibrated, in some cases as often as every two weeks, adds to the overall cost of ownership. Optical sensors have provided a much more stable measurement, but many types on the market are still slow to respond and require regular calibration due to degradation of the lumiphore material.Measuring DO levels within an aeration process can prove a challenge in such a harsh environment. With high-fouling water and high sediment loads passing through the secondary stage at a rapid flow rate, the instrument needs to be robust and reliable.In addition to this, installations can prove difficult as although the basic technology in aerationprocesses remain basically the same, the methods can vary from mechanical or surface aeration to diffusion. It can also be extremely inconvenient when a sensor needs to be frequently replaced.Finally, transmitter devices can be complicated to program and commission, with calibration details, serial numbers and lifetime indication requiring input.The solutionThese problems are overcome by ABB’s new ADS420 optical DO sensor. Able to be used standalone or as part of a complete aeration control system featuring other ABB equipment such as the ACQ580 variable frequency drive, the ADS420 can help to provide accurate and stable measurement of dissolved oxygen levels.Unlike other optical DO systems, the sensor can be deployed for extended periods of time without a need for calibration. Each sensor cap is individually calibrated and profiled to the lumiphorecharacteristics, which are continually monitored throughout the life of the sensor. This avoids the need for frequent recalibration.The sensor’s construction features lumiphore molecules embedded in a gas-permeable sensing foil element, a blue LED, a red LED, and photodiode. When the blue LED emits light, red photons are emitted, caused by excitation of the lumiphore molecules embedded in the gas-permeable sensing foil.Any oxygen molecules present in the foil quench the luminescence, causing a phase shift in the returned red light which is measured by the photodiode. This phase shift is measured by comparing thedifference between the original red reference light and the red light being returned. The higher the levelOxygen molecules react with the lumiphore foilLuminescence is quenched causing a phase shiftPhase shift is measured by the photodiode—Figure 1Optical sensors – how they workof dissolved oxygen present, the lower the amount of red light is returned.The DO concentration is calculated and relayed to the transmitter. The resulting information is then used to fine-tune dissolved oxygen levels to match the requirements of the process. By using the phase shift to measure the lifetime of the luminescence rather than its intensity, the sensor offers the highest accuracy and stability across the widest operating range.As the patented signal processing is up to five times faster than other optical systems, improved control of dissolved oxygen levels can be achieved, enabling a return on investment in as little as six months. Impervious to drift, the non-consumptive, non-reactive method is ideal for high-fouling environments and can withstand the harshest operating conditions.—What can ABB offer?Comprised of a sensor and multi-channel transmitter, ABB’s optical DO sensor system utilizes the latest advances in optical measurement technology to give you the highest levels of stability and accuracy for dissolved oxygen measurement.The AWT420 dual-channel transmitter provides true flexibility for measuring a wide variety of parameters in a single device. The AWT420 can be used with either analog or digital EZLink sensors, providing plug-and-play sensor connectivity, automatic sensor recognition/set-up and advanced predictive diagnostics. It features an SD port for data storage and graphical trending and is compatible with a range of communications, including HART, Ethernet, Modbus and Profibus. The Ethernet module contains an embedded webserver that enables the unit to be viewed remotely and fully controlled securely via a web browser. Configuration data and processdata can be downloaded via a secure FTP connection.Setting up the transmitter and sensor is easy. Simply connect the sensor using ABB’s EZLink connection and the transmitter will automatically configure the sensor set-up.Added simplicity is provided by the sensor’s smart sensing cap with automatic setup.The SmartCap comes pre-loaded with factory calibration coefficients, serial number, lifetime indication, and manufacture date which are automatically uploaded to the ADS420 opticalDO sensor.—Figure 2Comprised of a sensor and multi-channel transmitter, ABB’s optical dissolved oxygen system can deliversignificant savingsThe SmartCap is capable of up to 24 months of continuous operation, greatly reducing the requirement for maintenance. When the cap does need replacing, it will be as easy as the original installation – the calibration details will be pre-loaded and the transmitter will automatically recognize the new sensor.When cleaning is necessary, it can be cleaned and redeployed without calibration. For high-fouling applications, the sensor can be automatically cleaned using ABB’s auto-clean system. This system periodically injects a high pressure burst of air across the sensor surface to remove any fouling.The ADS420 sensor is available with a range of installation options, including dip mount systems, floating ball systems and chain mount immersion systems for open tank and channel installations, as well as a flow-through system for panel mount systems.As a way of boosting performance whilst minimising energy costs, the optical dissolved oxygen system is ideal for large-scale municipal and industrial wastewater treatment plants.It could also be used in any application where water must be cleansed before re-entering the water cycle, including aquaculture, dam or discharge monitoring and in food and beverage production processes.—A complete offering for aerationABB has extensive experience in the design, manufacture and lifelong support of aerationcontrol systems for water, wastewater and process applications. Additional products available includethe ACQ580 variable frequency drive, thermal massand electromagnetic flowmeters, pressure transmitters and the CM30 range of PID controllers.For more information contact your local sales representativeAN/ANALYTICAL/8-ENRev.A5.222—We reserve the right to make technical changes or modify the contents of this document without prior notice.
