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.

郑州炜盛电子科技有限公司MQ137氨气传感器产品描述MQ137气体传感器所使用的气敏材料是在清洁空气中电导率较低的二氧化锡(SnO2)。
当传感器所处环境中存在氨气时，传感器的电导率随空气中氨气的浓度的增加而增大。
使用简单的电路即可将电导率的变化转换为与该气体浓度相对应的输出信号。
MQ137气体传感器对氨气的灵敏度高，对其它有机胺（如三甲胺、乙醇胺等）的监测也很理想。
这种传感器可检测多种含氨气体，是一款适合多种应用场合的低成本传感器。
传感器特点本品在较宽的浓度范围对氨气有良好的灵敏度，具有长寿命、低成本、驱动电路简单等优点。
主要应用广泛适用于家庭用氨气报警器、工业用氨气泄漏报警器以及便携式氨气检测器。
