JUMO 201040 水溶氨气感应器简介说明书
Page 1/4Data sheet 201040Brief descriptionThis sensor can be used to measure ammonia (NH 3) in aqueous solutions. In an aqueous solution, ammonia is in a pH-dependent equilibrium with ammonium ions (NH 4+ ions). Provided the NH 4+ ions are converted into ammonia by adding lye, the sensor also detects the resultant ammonia. The NH 4+ ions themselves are not detected.The ammonia sensor consists of a pH glass electrode and a reference electrode. Both the electrodes are in an electrolyte. The electrolyte is separated from the process medium by a hydrophobic, gas-permeable membrane. The pH value of the electrolyte changes if NH 3 gas diffuses through the hydrophobic membrane. This local change in the pH value is measured at high resistance by the integrated pH electrode.JUMO ammonia sensors feature the advantage of having ready-made membrane caps. There is no need to put the sensitive membrane on by hand. With the JUMO sensor, the membrane cap is quickly and easily replaced as a complete unit.Monitoring ammonia leakage in refrigerating plantsRefrigerating plants (in indoor ice rinks or cold storage, for example) frequently use ammonia as a refrigerant. As ammonia (NH 3) is a toxic, pungent-smelling, colorless gas, the plants are monitored for escaping ammonia (leakage). Gas sensors are used to monitor the ambient air (these are not supplied by JUMO). In addition, the pipes and system components that carry the liquids are monitored for ammonia ingress. JUMO's ammonia-sensitive sensor can be used for this purpose. Measuring ammonia with a JUMO ammonia sensor gives a far more selective response than measuring the pH. The JUMO ammonia sensor can also be used in online analyzers/samplers or in the laboratory.More information can be found in JUMO white paper 631, "Information on measuring ammonia in water".Technical dataAnalyte aaThe sensor is used to detect NH 3 ammonia.

Ammonium ions (NH 4+) predominate in the acidic range and are not detected by the sensor!At a pH of approximately 9.3, the concentration ratio of ammonia (NH 3) and ammonium (NH 4+) is about 1:1.Ammonia is only dominant in the reaction in the heavily alkaline range.The process medium must not contain any substances that could damage the sensor membrane (such as oils, greases, particles of dirt or surfactants).Dimensions(1)Only NH 4+ ions (ammonium) present (2)The ratio of NH 4+ ions (ammonium) and NH 3(ammonia) is 1:1(3)Only NH 3 ions present(1)Pg 13.5 screw-on head (2)Hose connection (silicone)(3)Shaft (PPO)(4)O-ring (FPM)(5)Sleeve (PSU)(6)Membrane cap (stainless steel 1.4571)(7)Membrane (PTFE)Page 3/4Data sheet 201040AccessoriesThe purpose of the manual quick-change fitting is to hold the ammonia sensor. It protects the sensor against excessively high pressures during operation and limits the flow rate of the process medium through the measurement chamber.The throughput of measuring fluid depends on the viscosity and temperature of the medium and the pressure in the line it flows through.PTFE washers for normal flow rate (white) or increased flow rate (black) are available as accessories.(1)G 1/8A (POM) hose connection (2)Material PP(3)Shaft (PPO)(4)Replaceable PTFE washer AClosedBOpenManual quick-change fitting Part no.: 00379538Optimum operating pressure 2to 4bar Maximum operating pressure 6bar Operating temperature-8to +50°CPage 4/4Data sheet 201040Order detailsNote:The type code is not a modular system.If possible, choose items listed under "stock versions" or "production versions" for your orders.

NPTOptional HMIThe optional HMI Service/Display unit is used for commissioning and quick on-site setup and is easily mounted on the AKS 4100U.The service unit supports mulitple languages in both SI and US units.Measuring principle (Cable and Coaxial)The AKS 4100U electronic converter emits low-intensity, high frequency electromagnetic pulses with a width of approximately 1 nanosecond, which travel at the speed of light along the probe (wire or coaxial cable) down to the liquid surface.The pulses are reflected by the liquid surface, guided back along the probe, and received and analysed by the AKS 4100U electronic converter and then converted into a liquid level reading. This method is called time domain reflectometry (TDR) or guided microwave.The dielectric constant, εr, of the liquid is a key parameter and has a direct impact on the degreeof reflection of the high frequency electromagnetic pulses. Liquids with high εr values, such as ammonia, produce strong reflections, while liquids with low εr values, such as CO2, produce weak reflections.As long as the εr value of the liquid refrigerant is higher than 1.2, AKS 4100U can detect the liquid level and level measurement accuracy is not affected.If the temperature condition in the standpipe/vessel is known, a constant (dielectric constant of the refrigerant gas) can be entered (parameter 2.5.3 GAS EPS.R), in order to obtain improved Top and Bottom Dead Zone values.Refer to pages 7 to 8 for Measuring range of AKS 4100U - CABLE version and COAXIAL version.For details of gas constant values for different temperatures and refrigerants plus the procedure for entering these via the HMI, refer to pages 17 to 18.Main technical data (see a complete list of all technical data on page 11)Supply Voltage14 – 30 V DC.

氨气传感器应用手册说明书
氨气和氨气传感器氨气(NH3)是一种非常有用但又十分危险的气体。
当我们接触到氨气时，它会腐蚀我们的皮肤、眼睛和肺。
吸入氨气是非常危险的，因为它会刺激喉咙、鼻子和肺。
虽然氨气有害，但它是一个常用的化工原料，有许多工业应用。
氨气大量用于化肥、塑料、染料和纺织品的生产中，并大量用作制冷剂。
氨能被闻到吗?是的，人类可以闻到氨气。
然而，气味阈值因人而异。
一般来说，依靠你的嗅觉来确定是否存在氨气是不可靠的，这是因为当你习惯了这种气味后，你的鼻子就不那么敏感了，这种现象被称为嗅觉疲劳。
何时需要检测氨气?氨气在制造和工业过程中被大量使用。
在环境中，氨气是氮循环的一部分，由土壤中的细菌在分解有机物质的过程中产生。
包括植物、动物和动物粪便在内的有机物分解都会产生氨气。
环境中高浓度的氨气是危险的，所以在许多应用中，政府有各种各样的监管措施来控制氨气的暴露限度。
•由于其低成本和高能效，以及对环境的影响较小，氨气被广泛使用于大型制冷设备中，因此需要对设备进行泄漏检测以防人员中毒。
•氨气检测的最大应用之一是家禽养殖和生猪养殖场，控制氨气浓度能显著改善牲畜健康和有效提高产量。
•农业肥料硝酸铵的生产通常使用无水氨气和浓硝酸为原料。
监测氨气的浓度是一项必要的安全措施。
什么是安全的氨气浓度水平?各种政府机构和协会推荐了氨气暴露限值如表1所示。
氨气检测器如何工作?氨气检测器通常由电子电路和氨气传感器组成。
氨气传感器将检测到的气体浓度转换为电子信号，由机载微处理器分析。
接收信号后，处理器显示读数。
当测量值超过指定的报警值时，触发警报。
表1 -推荐氨气暴漏限值为您的应用选择合适的NH3传感器是很重要的，以下问题帮助您缩小氨气传感器的选择范围，更快地匹配您的应用:•快速响应时间对我的测试很重要吗?对于某些应用和某些法规，对响应时间(T90)有特定的要求，以满足安全标准。
盛密科技SemeaTech 生产的如下快速响应氨气传感器非常适合这类场合的应用：T90 < 40秒4NH3 - 500s、4NH3-1000ST90 < 45秒4NH3 - 100s、7NH3-100S、7NH3-200S、7NH3-1000S、7NH3-200S•是用于个人防护还是连续监测?如果响应时间不是很重要，并且是连续监测的情况下，最好选择使用盛密科技SemeaTech的非消耗型NH3传感器。

The gas reaches the working electrode of the sensor through the diffusion holes,an electrochemical redox reaction occurs on the porous micro-surface of the electrode,the solid electrolyte conducts electron transfer,and generate a current signal as an output.The current signal can characterize the gas concentration.2.Technical parameters[1]The time from when the sensor is powered on to when the data is read.Note the parameter when the sensor is powered on.[2]If started in an environment with clean air it requires less time.[3]The measurement data update interval,after the power-up warm-up time,if the power supply continues,the sensor periodically updates the reading at this interval.[4]T90＜30s3.RS-485Protocol3.1Introduction to Modbus-RTU RS-485Modbus protocol is a common protocol used in electronic devices.Through this protocol,the devices communicate with each other.It has become a common industry standard,widely used in data logger, sensor equipment and so on.Based on this protocol,devices from different vendors can communicate with each other for system integration.Modbus protocol is a master-slave architecture protocol.One node is the Master and the other nodes that use Modbus protocol to participate in the communication are Slaves.Each slave device has a unique address.The Sensor has RS485interface and supports Modbus-RTU.Modbus commands can be used to obtain sensor data or modify communication parameters.Note:Default communication parameters:Baud rate9600bps,one start bit,8data bits,no verification,one stop bit.3.2Modbus register●Modify the address Default address:0x0F (hex).Use special instructions to modify the address,range 0x01to 0XF7,out of range automatically reverts to 0x01The instruction header Modify the address 807265706F 6C 65766544xExample:The address needs to be changed to 0x02.Send command:807265706F 6C 6576654402Note:When modifying the Modbus address,a singlerefresh is required (there is one device on the bus).●Error

slave address is1,the function code is 03,the starting address is0,and the number is13.5Calibration Instructions4.Precautions(1)The main function of the gas sensor is to detect the gas composition and content,please do notlet any part of the sensor come into contact with liquids.(2)The sensor wire sequence cannot be reversed.Once reversed,it will cause permanent damageto the sensor and make it unusable.(3)Different gas sensors have different concentration measurement ing the sensor inenvironments with concentrations above the maximum range for a long period of time can damage the device.(4)The white or yellow sheet on the sensor is a waterproof and breathable membrane,please becareful not to scratch or cut it;(5)The ventilation surface of the sensor should not be blocked or polluted.Sometimes the cloggingof the hole can cause sensitivity reductions and slow response time.(6)To measure the gas sensitivity,avoid blowing the gas directly into the equipment,use standardgas caps.One side is the air intake,one side of the air outlet(under normal circumstances the small hole is the intake and the large hole lets the gas out);(7)Avoid excessive shocks or vibration.If the shell is damaged,please ensure that the sensor is notdamaged.If the shell is broken and the internal structure is exposed,the output will no longer be reliable(the signal may be too large,too small or no output).(8)It takes some time to return to the initial state after long-term exposure to high gasconcentrations.(9)When using a low-range sensor avoid exposing the sensor to air with high concentrations over along period of time.Long-term exposure to high concentrations of the gas can damage the sensor and decrease the performance.(10)Please do not disassemble the sensor,doing so might damage the sensor.(11)Please avoid instantaneous high voltages,which can seriously damage the sensor.(12)Calibration and detection,the electrochemical gas sensor's reaction activity with the target gaswill change with time,temperature,and humidity changes.Because the sensor outputs the relative changes in current it is necessary to calibrate it to accurately calculate the absolute concentration.First use a zero gas and a gas with a standard concentration.Calibrate the linear change of the gas to obtain a standard curve.When measuring,compare the electrical signal generated by the concentration of the gas to be measured with the electrical signal of the standard concentration to calculate the accurate gas concentration value.Therefore,zero-calibration and regular recalibration of the equipment are all necessary to ensure the accuracy of the measurement.(13)Cross interference of sensors.Generally speaking,each sensor corresponds to a specificdetection gas,but any gas sensor cannot be absolutely specific.Therefore,when using a gas sensor,try to avoid interference from other gases with the sensor to ensure its accurate detection of specific gases.(14)Measuring range and accuracy:select a gas sensor that matches the range and accuracy foryour application scenario,otherwise it may not be able to detect the gas and determine theaccurate data or the sensor may get damaged.(15)Storage environment:temperature(-5~+30℃),relative humidity50%RH(non-condensing);the storage environment should have clean air,no pollution,no acetone,no high-concentration organic gas,no dust,no Smoke;avoid storing with alcohol(ethanol),perfume,sodium silicate and polyurethane liquid or solid;avoid storing in high temperature and low humidity environment.(16)Transportation:For long-distance transportation,the temperature in the sensor package shouldbe kept within40°C,and the maximum temperature should not exceed55°C.The humidity should not be lower than15%RH.(17)Maintenance:The maintenance of the sensor mainly involves the calibration.Generally,thesolid polymer sensor does not consume chemical electrolyte,but due to the influence of temperature,humidity,dust,and other polluting gases,the sensitivity of the sensor will be affected.When an offset occurs,the hydrogen sulfide sensor needs to be recalibrated.The better the environment,the longer the sensor can go without requiring maintenance.The user should follow the precautions mentioned above.If improper use caused damage to the sensor, it is not covered under the warranty and we will not replace the device.5.Document version。
