The range consists of duct and space sensors.Space sensors have an option for humidity measurement.Features▪High quality thermistor temperature sensor ▪Humidity measuring option for space sensor ▪IP67 housing (duct sensor)▪Two part terminals to facilitate wiring ▪24 Vac/dc supply▪Adjustable depth duct mounting flange optionPhysicalCO2/T/../S26 mm (1.02”)ACC/FLANGE/12MM/5CO2/T/..Data SheetFUNCTIONALITYThe CO2/T.. series carbon dioxide and temperature sensors can be used for a wide range of HVAC applications, operating over a 0 to 2000 ppm concentration CO 2 range. The CO 2 sensor offers an accuracy of ±50 ppm +2% of measured value.The CO2/T/D duct sensor, as a temperature working range is -20 °C to +60 °C (-4 to +140 °F) utilising a 10 kohm at 25 °C thermistor temperature sensing element. Recommended scaling is given for 0 °C to +40 °C (32 to +104 °F). The CO2/T/../S space sensor, has temperature measurement range is 0 °C to +40 °C (32 to +104 °F) utilising a 10 kohmat 25 °C (77 °F) thermistor temperature sensing element. The output signal is 0 to 10 V corresponding to 0 to +40 °C (32 to+104 °F) with an accuracy of ±0.3 °C (±0.54 °F).The humidity sensor option on the CO2/T/H/S has a measurement range of 0 to 95 %RH range with ±3 %RH accuracy over 30 to 70 %RH, and ±5 %RH accuracy over 10 to 90 %RH. The output signal is 0 to 10 V corresponding to 0 to 100 %RH.INPUT CHANNELS AND SENSOR SCALINGThe input channel must be set to the appropriate input type (see controller documentation for details) and the sensor type module must be set up with the correct scaling.The recommended method of setting the sensor scaling is to use the ‘Unique Sensor Reference’ provided, see below for details.The scaling parameters used by SET can be seen when the sensor type is configured. If this is not suitable you can create your own sensor scaling using SET.Carbon dioxide concentration: The input channel used should be set for voltage (V), and sensor scaling set as below.Controller Unique Sensor ReferenceIQ3, IQ4, IQeco, IQ2 >v2.1 C02 V IQ1, IQ2 <v2.0Refer to the IQ ConfigurationManual (90-1533)Temperature: The input channel used should be set for voltage(V) for CO2/T/./H/S, and Thermistor (T) for C02/T/D, and sensorthe scaling set as below.CO2/T/./H/S Controller Unique Sensor Reference IQ3, IQ4, IQeco, IQ2 >v2.1 Temp V 0+40 for value in °CTemp V +32+40 F for value in °F IQ1, IQ2 <v2.0Refer to the IQ Configuration Manual (90-1533)C02/T/DController Unique Sensor ReferenceIQ3, IQ4, IQeco, IQ2 >v2.1 Thermistor HTST DT for valuein °CThermistor HTST DT F for value in °FIQ1, IQ2 <v2.0Refer to the IQ ConfigurationManual (90-1533)Humidity: The input channel used should be set for voltage (V), and sensor scaling set as below.Controller Unique Sensor ReferenceIQ3, IQ4, IQeco, IQ2 >v2.1 Humidity V IQ1, IQ2 <v2.0Refer to the IQ ConfigurationManual (90-1533)INSTALLATIONCO2/T/../SThe sensor housing consists of a front panel and a backplate. The backplate can be separated from the front panel by inserting a screwdriver in the bottom slot and twisting.Choose an accessible location for the sensor where the surrounding air temperature is representative of the room. The backplate is designed so that it can be mounted on a back box or a standard recessed wall box, or surface mounted with mini-trunking by using a knockout in one of the sensor’s side walls.The installation involves:Choosing locationMounting sensor (via two screws - minimum) Connecting terminals Assembling sensor unitSetting up IQ input channels to voltage (V) for CO2 concentration, temperature, and humidity (if option fitted).Configuring IQ sensor modules TestingFull installation details are given in the CO2/T/../S InstallationInstructions (TG201171).Data Sheet CO2/T/..CO2/T/DChoose an accessible location where the sensor element will lie in the airstream to be measured. Ensure that there is no stratification in the airstream being measured (i.e. downstream of mixing dampers, heating coils, cooling coils). Mount the probe in the duct by screwing the sensor box directly onto the duct. It should be mounted in the orientation indicated on the label on the side of the unit so that the air flows into and out of the inlet/outlet slots. The probe requires a 15 mm (0.59”) hole cut into the duct. The sensor box may be screwed directly to the duct using 2 screws at 85 mm (3.35”) centres. The installation involves:Choosing locationDrilling sensor probe hole Drilling fixing holesMounting sensor on prepared location Removing sensor lidFeeding IQ cables through gland Wiring cablesReplacing sensor lidSetting up IQ input channels to voltage (V) for CO 2 concentration and to thermistor (T) for temperature.Configuring IQ sensor modules Testing sensorThe optional mounting flange enables the probe depth to be adjusted by tightening the flange clamp to secure the position. It is screwed to the duct using 4 off screws at 45 mm (1.77”) centres.Full installation details are given in the CO2/T/D Installation Instructions (TG201170).COMPATIBILITYWhen connecting to an IQ4 controller the following limits apply if the IQ4 is to provide power.

A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.Models—Proximity ModeOverviewThe U-GAGE is an easy-to-use ultrasonic sensor, ideal for demanding environments. Simple push-button programming provides flexibility for a variety of applications. Excellent for measurement applications such as sensing of liquid levels in a tank or, for example, determining box heights for sorting purposes.Each sensor includes both an analog and a discrete output, which may be programmed independently with different window limits or together with identical limits. Each output has the option of being set with a sensing distance set point centered within a 10-mm window.U-GAGE® T30 Series with Analog and DiscreteOutputsFeatures and IndicatorsU-GAGE Figure 1. U-GAGE T30 Series sensor programming push buttons and indicatorsNote: All LED indicators momentarily turn off when the sensor changes state between Program and Run modes.The U-GAGE sensor has four LED indicators. The red Signal LED indicates the strength and condition of the sensor's incoming signal. Each amberOutput LED, whether analog or discrete, turns on when a target is sensed within the programmed window limits. The green Power ON/OFF LED indicates the operating status of the sensor. There are two modes of indication for the LED indicators: Run Mode and Program Mode.In Run mode:In Program mode:WiringNPN*It is recommended that the shield wire be connected to either earth ground or DC common.–+ PNP*It is recommended that the shield wire be connected to either earth ground or DC common.–+Cabled wiring diagrams are shown. Quick disconnect wiring diagrams are functionally identical.Configuring a Sensor Window LimitsWindow limits can be taught to the sensor in several ways, using either the push buttons on the back of the sensor or remote input.Note: When the sensor changes state between PROGRAM and RUN modes, all of the LED indicators turn OFF momentarily,before the appropriate LEDs come ON as described below. The sensing window limits expand temporarily to full scale (max range) during PROGRAM mode.Remote InputTo program the sensor remotely or to disable the keypad, use the Remote Programming function. In addition to programming the sensor, use the remote input to disable the buttons for security, preventing unauthorized or accidental programming changes. Connect the gray wire of the sensor to +12 V dc to 24 V dc, with a remote programming switch connected between them.Note: The impedance of the remote teach input is 55 kΩ.Programming is accomplished by following the sequence of input pulses. The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, are defined as: 0.04 seconds < T < 0.8 seconds.Note: To exit PROGRAM mode without saving any changes, hold the Remote line high > 2 seconds (before teaching the second limit). The sensor reverts to the last saved program.LimitOutput 2 Limits OnlyLimitLimitPush Button Locked out(or Enabled)Output 1Limits OnlyLimit Both OutputsTogetherPush ButtonLockout (or Enable)0.04 sec < T < 0.8 secFigure 2. Timing programs for remote TEACH programmingGeneral Notes on Configuration•The sensor returns to Run mode if the first TEACH condition is not registered within 120 seconds.•After the first limit is taught, the sensor remains in Program mode until the TEACH sequence is finished.•To exit PROGRAM mode without saving any changes, press and hold the programming push button > 2 seconds or hold the Remote line high > 2 seconds (before teaching the second limit). The sensor reverts to the last saved program.Configuring Limits for Either Analog or Discrete OutputNote: To exit PROGRAM mode without saving any changes, press and hold the programming push button > 2 seconds or hold the Remote line high > 2 seconds (before teaching the second limit). The sensor reverts to the last saved program.1.Choose the output for the first set of window limits (analog or discrete).2.Configure the first limit.3.Teach the second limit.4.Repeat for the other output (analog or discrete) if a second output is desired.Configure Analog or Discrete Limits Using the Auto-Zero FeatureFor some applications, a sensing distance set point centered within a minimum sensing window may be required. The TEACH procedure for this application is simple: configuring the same limit twice causes the sensor to program a 10-mm window centered on the position taught (position ±5mm).Note: The sensor allows for some forgiveness in this procedure. If the two limits are not exactly the same (but closer than the minimum 10-mm window required), the sensor places the set point at the average of the two limits.Configuring Identical Limits for Both Analog and Discrete Outputs SimultaneouslyTo set both the analog and the discrete outputs at exactly the same limits, both may be set simultaneously.1.Enter PROGRAM mode.2.Configure the first limit.3.Teach the second limit.Push Button LockoutAnalog OutputThe U-GAGE T30 Series series sensor may be configured for either a positive or a negative output slope, based on which condition is taught first (see Figure 3 on page 6). If the near limit is taught first, the slope is positive; if the far limit is taught first, the slope is negative. Banner’s scalable analog output automatically distributes the output signal over the width of the programmed sensing window.The U-GAGE T30 Series also features a 2-second hold upon loss of the received analog signal, which is useful for harsh and unstable applications.In the event of analog signal loss for longer than 2 seconds, the analog output goes to 3.6 mA or 0 V dc, which may be used to trigger an alarm.Current-Sourcing Models Target Position Positive SlopeNear WindowFar WindowA n a l o g O u t p u t (m A )204Negative SlopeVoltage-Sourcing ModelsTarget PositionPositive SlopeNearWindowFar WindowV o l t a g e O u t p u t (V d c )100Negative SlopeFigure 3. Positive and Negative Output SlopesNote: The analog current output tracks slightly past each window limit (from 3.8 to 20.5 mA).Self-Diagnostic Error ModeIn the unlikely event of a microprocessor memory error, all of the LEDs will flash in sequence. If this occurs, the setup parameters have been lost and the sensor may be corrupt.

其中颗粒物浓度的监测基于激光散射原理,可连续采集并计算单位体积内空气中不同粒径的悬浮颗粒物个数,即颗粒物浓度分布,进而换算成为质量浓度。
甲醛浓度的监测基于电化学原理,具有高精度、高稳定性的特点。
传感器同时内嵌瑞士生产的温湿度一体检测芯片。
颗粒物浓度数值、甲醛浓度数值及温度、湿度合并以通用数字接口形式输出。
本传感器可嵌入各种与空气质量监测和改善相关的仪器设备,为其提供及时准确的环境参数。
工作原理本传感器采用激光散射原理。
即令激光照射在空气中的悬浮颗粒物上产生散射,同时在某一特定角度收集散射光,得到散射光强随时间变化的曲线。
进而微处理器利用基于米氏(MIE)理论的算法,得出颗粒物的等效粒径及单位体积内不同粒径的颗粒物数量。
传感器各功能部分框图如图1所示图1 传感器功能框图甲醛监测功能采用电化学原理实现,加入数据处理算法,所获得的数据稳定、精确。
技术指标如表1所示表1 传感器技术指标数字接口定义PIN1图2 接口示意图输出结果1.颗粒物浓度:主要输出为单位体积内各浓度颗粒物质量以及个数,其中颗粒物个数的单位体积为0.1升,质量浓度单位为:微克/立方米(μg/m³)。
此外传感输出分为主动输出和被动输出两种状态。
传感器上电后默认状态为主动输出,即传感器主动向主机发送串行数据,时间间隔为200~800ms,空气中颗粒物浓度越高,时间间隔越短。
主动输出又分为两种模式:平稳模式和快速模式。
在空气中颗粒物浓度变化较小时,传感器输出为平稳模式,即每三次输出同样的一组数值,实际数据更新周期约为2s。

英国Dart Sensors 甲醛传感器
中文数据手册
绪论
Dart sensor公司生产的电化学式甲醛气体传感器是真正能够连续监测的传感器,而不需要任何的气体采样或者采用气泵抽取。
这种传感器是从我们已经成功应用的呼吸式酒精传感器基础上开发出来的。
适合于绝大多数的环境(-20℃~+50℃)监测使用(如有特殊介绍,可应用于更高的温度中)。
这款传感器有六大设计结构特点:
低成本
设计构造简单以及很少的部件使得其成本得到降低,从而形成更有竞争力的价格。
长寿命
它使用的是在世界范围内已经有30多年使用经验的呼吸酒精传感器的元件。
而呼吸酒精传感器的精度,稳定性和长久性都是已经得到了验证的。
响应快速
一条短小且低阻抗的扩散路径使其响应时间很少
电源要求低
燃料电池原理意味着它并不需要电源激励,仅仅在信号的处理和显示时需要电能,所以仅仅一个简单的小电池单元即可。
稳定性
非常好的稳定性,允许在使用过程中非常长的校准周期
可承受高压
采用非薄膜构造,不包含在高压环境下容易破碎的元件,经验证,可以承受10个大气压力。
工作原理
传感器内部包含一个常规的两电极燃料电池传感器。
工作电极通过外电路将电子释放到计数电极,并且在计数电极端随着氧的减少而消耗,内电路由电解液中的离子流来实现。
设计精良,便于电解液的消长。
电解液的消长随环境温度和湿度的变化而变化,但是仍可正常工作不会影响到校准值。
传感器电路
Dart公司的甲醛传感器输出的电流值于空气中从0到高浓度的甲醛浓度呈线性关系。
输出信号需要根据精确度要求进行放大和温度补偿。
信号放大
输出信号放大的首选方法是使用一个直接的电流到电压放大的运算放大器。
这样的话传感器将工作在其最好的模式下。
得到的信号值取决于反馈电阻的大小;比方说使用1000欧姆的电阻值,那么一个输出为5nA的信号将会转化为5mV的输出信号。
因为在开路状态传感器可能会逐渐引起偏移,虽然不会对产品有损伤,但是也要花费时间去放电。
所以在储藏期间一般将输出端子进行短路处理,这样就不会出现明显的长期的偏移量。
在使用过程中,为了避免在放大器被断开的时候偏移量的增加,可以在两端子之间连接一个低阻值的电阻(典型值为620欧姆)。
另外,也可将放大器持续供电。
下面给出典型的应用电路:
在高精度测量中反馈电阻应为470K,同时并联一个4.7μF的钽电容在没有反向响应时间的情况下降噪。
注意:该电路使用的是双路电源,这样能得到最佳效果。
在这个电路(以及类似的电路)里面,运算放大器我们推荐使用Burr-Brown的OPA177。
另外,也可以选用低功率而且噪声非常微小的OPA241。
这两种型号的器件本身的漂移量都很小,灵敏度又非常高,而且很容易加入到偏移整顿电路中去消除剩余的漂移量。
我们已经完成了使用类似OP90这种专用的运算放大器的单路供电电路的研究,并不推荐使用。
如果采用3V供电的话,我们推荐使用诸如ICL7660这样的IC产生的负电源。
温度补偿
如果需要的测量精度很高,那么就需要给电路中加入温度补偿的部分。
一般来说,在简单电路里面,我们可以通过在运算放大器的反馈回路中适当的加入一个热敏电阻来实现(该热敏电阻可以通过与其他的电阻的串并联进行修正)。
如果使用微处理器电路的话,在软件的控制下,热敏电阻补偿会更加精确。
标准的负温度系数热敏电阻提供的信号是比较合适的。
温度依赖性有两个部分:
1.气体的扩散率随温度的增长而增长。
2.低温下,电解质的功效将会明显削弱,这将成为决定比率的因素。
线性
甲醛传感器的线性至少为5ppm
产品构造
产品的尺寸为35mm的方形,9.5mm的高度。
在四个角的位置各有一个安全的孔。
表面上有一个可以接入1.5mm*31mm的ID口的O形凹槽,确保了产品的密封性。
这样可以防止污染气体从传感器后面进入而引起的读数错误的现象出现。
灵敏度
灵敏度取决于传感器表面的通路孔径的大小;孔径越大,扩散到传感器中的气体就越多,信
号也就越强。
标准的(最小实际孔径)单一中心孔径的直径为1mm,也可以根据客户的需求进行订制。
选择孔径要考虑到能够产生合适的信噪比,但是也要避免气体样品过量,否则会导致输出非线性,反应迟缓以及气体清洗不干净等问题出现。
交叉灵敏度
甲醛传感器主要对挥发的甲醛敏感,但是对于其他的气体或蒸汽也有一定的灵敏度(第一页的表格中提及)。
传感器本身不具有灵敏度的气体或者蒸汽包括:例如甲苯这样的饱和芳烃;丙酮,氨,氮,氧,氯,水蒸气及二氧化碳。
校准:
甲醛测定仪器标准的校准方法为渗透管,尽管如此,我们基于在呼吸酒精工业中广泛使用的液体标准概念开发并提供了一种简单的选择性方法,这依赖于这样一个事实:在特定的温度下,水和顶端空气之间的挥发性隔离层是恒定不变的。
我们提供两种浓度:在20℃时0.1和 1.0ppm,这种溶液的依据的是美国环保代理处的网址刊登的数据(遗憾的是链接现已过期),溶液恒温至20℃,以下的校正曲线可以用来修正温度数据
