MQ137 Test CircuitInstructions: The above fig is the basic test circuit of MQ137.The sensorrequirestwo voltageinputs: heater voltage(V H ) and circuit voltage(V C ). V H is used to supply standard working temperature to the sensor and it can adopts DC or AC power, while V RL is the voltage of load resistance R L which is in series with sensor. Vc supplies the detect voltage to load resistance R Land it should adopts DC power.Description of Sensor CharactersNH3 AirCautions1 .Following conditions must be prohibited1.1 Exposed to organic silicon steamSensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must be avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. 1.2 High Corrosive gasIf the sensors are exposed to high concentration corrosive gas (such as H 2S, SO X , Cl 2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. 1.3 Alkali, Alkali metals salt, halogen pollutionThe sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorine.1.4 Touch waterSensitivity of the sensors will be reduced when spattered or dipped in water. 1.5 FreezingDo avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 1.6 Applied higher voltageApplied voltage on sensor should not be higher than stipulated value, even if the sensor is not physically damaged or broken, it causes down-line or heater damaged, and bring on sensors’ sensitivity characteristic changed badly.1.7 Voltage on wrong pinsFor 6 pins sensor, Pin 2&5 is heating electrodes, Pin (1,3)/(4,6) are testing electrodes (Pin 1 connects with Pin 3, while Pin 4 connects with Pin 6).If apply voltage on Pin 1&3 or 4&6, it will make lead broken; and no signal putout if apply on pins 2&4.Fig7. Lead sketch2 .Following conditions must be avoided 2.1 Water CondensationIndoor conditions, slight water condensation will influence sensors’ performance lightly. However, ifwater condensation on sensors surface and keep a certain period, sensors ’ sensitiv e will be decreased. 2.2 Used in high gas concentrationNo matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensorscharacteristic will be affected.

氨气传感器原理氨气传感器是一种用于测量空气中氨气浓度的仪器,它可以广泛应用于农业、环境保护、工业等领域。
传感器的原理是基于氨气的电化学反应,在电极上产生电流或电压信号,进而测量氨气浓度。
本文将介绍氨气传感器的原理及其应用。
氨气传感器主要使用的传感元件是氨气电化学传感器,它利用氨气的电化学反应测量氨气的浓度。
一般来说,氨气电化学传感器由三个基本部分组成:工作电极、参考电极和电解质。
1. 工作电极:在氨气溶液中,工作电极表面的铂金属上发生氧化还原反应,其中氧化反应是把氨气氧化为氮气,还原反应是把氧气还原为水。
这些反应产生的电流或电势与氨气浓度成正比。
2. 参考电极:参考电极通常使用银/银氯化物电极或银电极。
3. 电解质:电解质通常是含有钾离子的盐水溶液,它的主要作用是传递离子电流。
当氨气接触到工作电极时,它会发生电化学反应,产生电荷,并且改变电化学反应的方向。
在测量过程中,电解质中的外部电源引起的电流可以表示氨气与铂电极之间的交互作用。
随着氨气浓度的增加,工作电极中反应的速率随之增加,电位变化也随之增大。
电位或电流的测量可以被用来评估气体浓度。
二、应用领域1. 农业:氨气传感器可用于测量畜禽场等场所的氨气浓度,帮助农民了解空气质量,保护动物健康,减少氨气的挥发和排放,改善环境质量。
2. 工业:氨气传感器可以用于化学处理、卫生清洁、医药制造和其他工业应用中氨气检测,以保护工人健康和安全,防止化学品泄漏和火灾等意外事故发生。
3. 环境保护:氨气传感器可用于测量高氨气浓度的空气污染源,例如农场、污水处理厂、化肥工厂、垃圾填埋场等,掌握状况,制定控制策略,减少氨气排放对环境的影响。
4. 医学:氨气是肝脏疾病的重要生物指标,它能够反映肝脏的代谢活动和功能状态。
利用氨气传感器可以测量人体呼出气中的氨气浓度,从而诊断肝脏疾病。
氨气传感器具有测量范围广、响应时间快、灵敏度高、可重复使用等优点,可以满足不同领域的需求,为实现环保和保障人的健康发挥重要作用。
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。
氨气NH3传感器电化学气体传感器、红外气体传感器、催化燃烧气体传感器输出都是微小的模拟信号,一般用户不可以直接使用这些传感器,因此圣凯安科技研究出来一个相对独立的微型数字智能单元,此单元以模拟信号 0-5V/4-20mA和数字串口信号输出。
智能传感器通过测试数据传输或接收指令来实现:标定、漂移和非线性进行补偿、零点温漂补偿、参数的设置、内检参数设置、测试数据输出等。
智能传感器使用则大有改观,首先自诊断功能在电源接通时进行自检,诊断测试以确定模组有无故障; 其次根据使用时间可以在线进行校正,微处理器利用存在 EPROM 内的的标定数据,进行对比校对。
4NE和7NE 系列是专门针对气体探测器生产企业推出的新型智能传感器,主要为解决气体探测种类繁多、各品种传感器互不兼容、生产标定复杂、核心器件更换限制等问题。
