中,英己送出A transducer is a device that converts one type of energy to another. The conversion can be to/from electrical, electro-mechanical, electromagnetic, photonic, photovoltaic, or any other form of energy. While the term transducer commonly implies use as a sensor/detector, any device which converts energy can be considered a transducer.Transducers are electric or electronic devices that transform energy from one manifestation into another. Most people, when they think of transducers, think specifically of devices that perform this transformation in order to gather or transfer information, but really, anything that converts energy can be considered a transducer.Transducers that detect or transmit information include common items such as microphones, Geiger meters, potentiometers, pressure sensors, thermometers, and antennae. A microphone, for example, converts sound waves that strike its diaphragm into an analogous electrical signal that can be transmitted over wires. A pressure sensor turns the physical force being exerted on the sensing apparatus into an analog reading that can be easily represented. While many people think of transducers as being some sort of technical device, once you start looking for them, you will find transducers everywhere in your everyday life.Most transducers have an inverse that allows for the energy to be returned to its original form. Audio cassettes, for example, are created by using a transducer to turn the electrical signal from the microphone pick-up – which in turn went through a transducer to convert the sound waves into electrical signal – into magnetic fluctuations on the tape head. These magnetic fluctuations are then read and converted by another transducer – in this case a stereo system – to be turned back into an electrical signal, which is then fed by wire to speakers, which act as yet another transducer to turn the electrical signal back into audio wavesOther transducers turn one type of energy into another form, not for the purpose of measuring something in the external environment or to communicate information, but rather to make use of that energy in a more productive manner. A light bulb, for example, one of the many transducers around us in our day-to-day lives, converts electrical energy into visible light. Electric motors are another common form of electromechanical transducer, converting electrical energy into kinetic energy to perform a mechanical task. The inverse of an electric motor – a generator – is also a transducer, turning kinetic energy into electrical energy that can then be used by other devices.As in all energy conversions, some energy is lost when transducers operate. The efficiency of a transducer is found by comparing the total energy put into it to the total energy coming out of the system. Some transducers are very efficient, while others are extraordinarily inefficient. A radio antenna, for example, acts as a transducer to turn radio frequency power into an electromagnetic field; when operating well, this process is upwards of 80% efficient. Most electrical motors, by contrast, are well under 50% efficient, and a common light bulb, because of the amount of energy lost as heat, is less than 10% efficient.What is the Difference Between Transducers and SensorsTransducers are machines used to change one type of energy into another. They can often be found as a component of more complex devices. Sensors are explicitly intended to measure and express levels of measurement. Quite often, sensors are composed of transducers; therefore, one can see how easy it can be to confuse the two.Generally, transducers come in basic varieties of which there are almost endless applications. The first variety is contact transducers. This type is categorized by a single point of contact used to detect energy. There is generally a coupling material, such as water or oil, employed in order to prevent distortion between the source of energy and the point of detection.Many sensors utilize contact transducers in order to detect energy levels and convert that into an electrical energy which would then influence a display meter. One type of contact transducer that was almost ubiquitous in the late 1980s and early 1990s were tape heads. These were found in any cassette player, touching the magnetic tape and reading the magnetic information that was on it. This information was then converted to an electric signal that was carried by wire to speakers or headphones and then converted back into sound waves.The second most common type of transducers is the immersion type. These are intended to work in liquid 。

室内空气质量检测与传感器的应用 [摘要]室内空气品质对人的影响至关重要,利用传感器检测空气质量是当今流行的一种方法,本文介绍了传感器在空气质量检测方面的原理应用,分析了当前气体传感器的优点和不足,以及气体传感器的发展趋势和前景。
[关键词]空气质量 气体传感器 室内环境污染 一、空气对于人的重要性 人们每时每刻都离不开氧,并通过吸入空气而获得氧。一个成年人每天需要吸入空气达6500升以获得足够的氧气,因此,被污染了的空气对人体健康有直接的影响。
人的一生中有90%以上时间在室内度过,可见,室内空气品质对人的影响更是至关重要。 二、室内环境污染背景 当今,人类正面临“煤烟污染”、“光化学烟雾污染”之后,又出现了“室内空气污染”为主的第三次环境污染。
美国专家检测发现,在室内空气中存在500多种挥发性有机物,其中致癌物质就有 20多种,致病病毒 200多种。危害较大的主要有:氡、甲醛、苯、氨以及酯、三氯乙烯等。
大量触目惊心的事实证实,室内空气污染已成为危害人类健康的“隐形杀手”,也成为全世界各国共同关注的问题。据统计,全球近一半的人处于室内空气污染中,室内环境污染已经引起35.7%的呼吸道疾病,22%的慢性肺病和15%的气管炎、支气管炎和肺癌。
三、关于开展室内空气质量服务的几点设想 1.着手调查国内家庭和办公室内空气质量的基本情况。 2.了解并着手引进室内空气质量检测设备。
3.进行规模较大的宣传活动,首先应由气象主管部门与环保主管部门联合建立室内空气质量问题的管理机制。 4.对国际环保部门有关室内空气质量的法规、技术标准、室内污染测定方法及对测定仪器等问题进行专门的调查和研究。
四、空气检测仪的强力武器——传感器 检测技术是人们认识和改造世界的一种必不可少的重要技术手段。而传感器是科学实验和工业生产等活动中对信息资源的开发获取、传输与处理的一种重要工具。
下面将介绍六种在空气质量检测方面发挥重要作用的传感器。 1.金属氧化物半导体式传感器。
金属氧化物半导体式传感器利用被测气体的吸附作用,改变半导体的电导率,通过电流变化的比较,激发报警电路。由于半导体式传感器测量时受环境影响较大,输出线形不稳定。
金属氧化物半导体式传感器,因其反应十分灵敏,故目前广泛使用的领域为测量气体的微漏现象。 2.催化燃烧式传感器。
催化燃烧式传感器原理是目前最广泛使用的检测可燃气体的原理之一,具有输出信号线形好、指数可靠、价格便宜、无与其他非可燃气体的交叉干扰等特点。催化燃烧式传感器采用惠斯通电桥原理,感应电阻与环境中的可燃气体发生无焰燃烧,是温度使感应电阻的阻值发生变化,打破电桥平衡,使之输出稳定的电流信号,再经过后期电路的放大、稳定和处理最终显示可靠的数值。
3.定电位电解式传感器。定电位电解式传感器是目前测毒类现场最广泛使用的一种技术,在此方面国外技术领先,因此此类传感器大都依赖进口。
定电位电解式气体传感器的结构:在一个塑料制成的筒状池体内,安装工作电极、对电极和参比电极,在电极之间充满电解液,由多孔四氟乙烯做成的隔膜,在顶部封装。前置放大器与传感器电极的连接,在电极之间施加了一定的电位,使传感器处于工作状态。
气体与的电解质内的工作电极发生氧化或还原反应,在对电极发生还原或氧化反应,电极的平衡电位发生变化,变化值与气体浓度成正比。 4.迦伐尼电池式氧气传感器。
迦伐尼电池式氧气传感器的结构:在塑料容器的一面装有对氧气透过性良好的、厚10-30μm的聚四氟乙烯透气膜,在其容器内侧紧粘着贵金属(铂、黄金、银等)阴电极,在容器的另一面内侧或容器的空余部分形成阳极(用铅、镉等离子化倾向大的金属)。用氢氧化钾。
氧气在通过电解质时在阴阳极发生氧化还原反应,使阳极金属离子化,释放出电子,电流的大小与氧气的多少成正比,由于整个反应中阳极金属有消耗,所以传感器需要定期更换。目前国内技术已日趋成熟,完全可以国产化此类传感器 5.红外式传感器。
红外式传感器利用各种元素对某个特定波长的吸收原理,具有抗中毒性好,反应灵敏,对大多数碳氢化合物都有反应。但结构复杂,成本高。
6.PID光离子化气体传感器。PID由紫外灯光源和离子室等主要部分构成,在离子室有正负电极,形成电场,待测气体在紫外灯的照射下,离子化,生成正负离子,在电极间形成电流,经放大输出信号。
PID具有灵敏度高,无中毒问题,安全可靠等优点。 五、气体检测仪器仪表产业发展现状深度分析 近年来,随着中国经济的高速发展,仪器仪表产业也得到了快速发展,自2004年产销首次突破千亿元大关,行业发展进入了快车道,2006年行业总产值突破两千亿元;2007年仪器仪表行业总产值达3078亿元,增长率高达28.5%;据仪器仪表行业协会统计,08年上半年仪器仪表行业总产值实现 1755.9亿元,同比增长23.8%,其中分析仪器、环境监测仪器仪表增长率高达32%。
科学技术的进步为气体检测仪器仪表行业的发展提供了条件,市场和政府政策的推动、人们安全意识的提高、相关法规法。
