SGX Infrared Single Gas Sensor for Hazardous Envir
___________________________________________________________________________________________Whilst SGX has taken care to ensure the accuracy of the information contained herein it accepts no responsibility for the consequences of any use thereof and also reserves the right to change the specification of goods without notice. SGX accepts no liability beyond the set out in its standard conditions of sale in respect of SGX Europe Sp. z o.o. Building 11Ligocka St. 103, 40-568 Katowice, PolandT: +48 (0) 32 438 4778E:**************************IR1 Single Gas Series DatasheetInfrared Single Gas Sensor for Hazardous Environments(Portable and Fixed Systems)The SGX infrared sensors use the proven Non-Dispersive Infrared (NDIR) principle to detect and monitor the presence of gases. With an infrared source and specific filtering on the pyroelectric detectors mounted inside the optical/gas cavity, individual gases or types of gas can be identified and their concentrations determined.These sensors are suitable for reliable monitoring of gas levels in general safety applications where the sensor size is restricted and require a flameproof enclosure for hazardous environments.APPLICATIONS∙ Oil & Gas∙ Petrochemical ∙ Biogas∙Wastewater ∙ Utilities ∙ Steelworks∙ Confined Space Entry ∙ Indoor Air QualityFEATURES∙For detection of the following gases:o Carbon Dioxide (IR11 Series),o Hydrocarbons (IR12 series, IR13 series) o Acetylene (IR14 series) ∙Gas concentration ranges:o 0 - 5% Carbon Dioxide(also suitable for 0 to 0.5%v/v) o 0 - 100% Carbon Dioxide(also suitable for 0 to 10%) o 0 - 100%v/v Hydrocarbons(also suitable for 0 to 100%LEL) o 0 - 100%v/v Acetylene(also suitable for 0 to 100%LEL)∙ 16.6mm or 19.0mm sensor heights available∙ Embedded temperature sensor in some versions for improved temperature compensation∙ Shock-resistant IR Source version available on certain types∙ Diffused gas sampling via mesh ∙ Low power∙ Reference channel for self-compensation∙ Special gold plated optical gas cavity for stable signal levels∙ Operational in varying temperature, pressure and humidity∙ Fast response∙ Rugged stainless steel construction ∙ No moving parts∙ Immunity from ‘poisoning’ ∙Reliable fail-safe operation∙Certified: ATEX, IECEx, CSA and ULOPERATIONTo operate, the sensors must be interfaced to a suitable circuit for power supply, output amplification and signal processing. Sensor outputs require linearisation and compensation for ambient temperature variation using algorithms in the system firmware. This is necessary for sensors to meet their full performance specification. An embedded temperature sensor facilitates this compensation on certain types. Further compensation for pressure changes can also be made in an algorithm, provided there is a suitable input from a pressure sensor.A set of Application Notes is available from the SGX Sensortech Ltd website, to explain more about NDIR gas sensing and provide advice for the end-user on interfacing the sensors and processing signals.TECHNICAL SPECIFICATIONCONFIGURATIONSsuitable. The use of the sensor beyond these ranges will affect the sensor’s perf ormance.** All sensors use temperature compensated pyroelectric detectors except for IR1nBD variants which are uncompensated. This refers to a change in the DC voltage output only. Further temperature compensation is required for all sensor variants.HANDLING PRECAUTIONS1. Do not allow sensors to fall on the floor. This could cause IR Source filament breakage, damage to the pins and the gasentrance aperture.2. Do not apply mechanical force against the gas entrance aperture.3. Do not immerse sensors in water or other fluids.4. Protect the gas entrance aperture against dust ingress and sprayed materials.5. Anti-static handling precautions must be taken.PERFORMANCEFor test purposes, all data taken using the following conditions:- Performance as tested in the SGX IR-EK2 Evaluation Kit directly after calibration.- SGX linearisation and temperature compensation algorithms applied; see Infrared Sensor Application Notes.- IR Source Voltage 5V, square wave, at 4 Hz and 50% duty cycle. Running the IR Source at 3V will decrease performance due to lower output signals.- Ambient temperature (20°C) and pressure (101 kPa).- All gases diluted in dry nitrogen.- Performance for the Hydrocarbons refers to Methane only. Most other hydrocarbons will have an improved performance.- Performance data is the same for the supported IR Source variants (“_1” variants).- Refer to Application Notes for more information.(2) Production Test Limits, using standard test gases of Dry Nitrogen, 2%v/v Carbon Dioxide, 5%v/v Methane and 1.15%v/v Acetylene, where appropriate .(3) A 0.30 absorbance is equivalent to a 30% decrease in the Active peak-to-peak output.(4) The minimum detection level is the smallest detectable change in concentration based upon a 2 sigma variantion. The best detectable change occurs at 0% gas concentration due to the non-linear output of the detector (see Fractional Absorbance Curves).(5) Performance for most hydrocarbons will be better than for methane for equiavlent concentrations, as methane is one of the lower sensitive gases compared to other hydocarbons.(6) After linearisation using the recommended method of linearisation and based upon a calibration gas with a concentration >75% of the full-scale. (7) Using average Alpha and Beta coefficients based upon test data from the instrument in which the sensor is being tested. Refer to Application Notes for information on calculating Alpha and Beta coefficients. Accuracy can be improved by measuring each sensor over temperature to define specific Alpha or Alpha & Beta coefficients.(8) After sensor stabilisation and over a period of 8 hours.(9) Difference in response when changed from 0 %RH to 90 %RH.(10)Sensors can be used over a greater ambient pressure using pressure compensation of the concentration. An external pressure sensor will be requred for this.FRACTIONAL ABSORBANCE CURVESThese show the typical sensitivity versus concentration before linearisation for the range of gases. For further explanation, refer to the Infrared Sensor Application Notes.Primary Target GasesIR11GM_1IR12BD IR12EM IR12GM IR12GM_1 IR13BDOther Target GasesIR12GM_1IR12GM_1 IR12GM_1IR12GM_1CERTIFICATIONSCSAULATEXIECEXINSTRUCTIONS SPECIFIC TO HAZARDOUS AREA INSTALLATIONS(Ref: EU ATEX Directive 2014/34/EU)1. The IR1xxx Series Gas Sensing Heads are component-approved only and may not be used as stand-alone items in ahazardous area without further protection.2. The IR1xxx Series Gas Sensing Heads shall be protected in service. The Sensing Head shall be mounted in a protectiveenclosure such that an impact of 7 J in accordance with IEC 60079-0:2007 clause 26.4.2 from any direction shall not cause the impact head to make contact with the Sensing Head.3. The thermal resistance of the IR1xxx Series Gas Sensing Heads does not exceed 25 K/W. This shall be taken into accountwhen considering its surface temperature and the temperature classification of the equipment into which it is to be incorporated. Tests indicated that an internal ignition raises the temperature of the mesh by a further 4.2 K (including a 1.2 safety factor).4. The IR1xxx Series Gas Sensing Heads have not been assessed as a safety device (EHSR 1.5).5. There are no user-serviceable parts in the component.6.

关于自络清纱器问题及解决方法
关于自络清纱器问题及解决方法1、支偏，指的是不是电清突然间一直不停的切纱？或者是单锭长时间下来都发生支篇切纱？1、1如果是突然间发生，可以更换一根管纱试试。
如果支偏设置很严格的话，如 7%, 8%，支偏无法以肉眼辨识。
只能将管纱拿到试验室秤其格林数，不过得注意这根管纱，所含支偏细纱到底有多长。
1、2如果长时间下来，都是固定一锭（例如＃12锭）发生支偏切纱数值高。
可以将检测头与相邻的正常锭（例如11锭）交换，看看问题是不是仍然发生在原来的第＃12锭，如果是，问题可能发生在机械问题，看看退绕中的管纱，经过检查槽时是否稳定。
管纱退绕时的张力、气圈关系着细纱通过检测槽时的稳定度。
当然，也可以更换评价电路版。
以过滤方式，将问题找出来。
1、3如果支偏乱切现象还是发生在原来的那个检测头（就是原来支偏乱清的第12锭检测头，目前在第11锭运转），该检测头可能需要校正，或是清洁。
1、4交换过检测头或是评价电路版的两个锭子，不要忘了先执行『单锭微调』。
结：其实，严格说来，支偏叁数的设定是否恰当，也关系着切纱数的徒然增加或减少。
细纱机纺出来的每根管纱，从满管道管脚，毛羽相差约 10%。
多出来的毛羽，都会视为支偏。
有SFI, SFI/D 功能的系统就可以分辨出来，不过设定太严也是会被切除。
因此，支偏设定太过严苛，当发生支偏切纱时，不妨看看是不是该锭正在退绕毛羽高的管脚纱。
尤其是天气湿度的变化，也会左右管纱毛羽的增减。
根据我的经验，发生支偏切纱过多，大多数都是因为设定太过严苛。
当然，这要在络筒机退绕稳定情况的前提之下。
2、支偏设定与条干CV%、长粗节、长细节是什么关系？2、1洛菲对支偏的定义，共分长错支、短错支两个通道。
设定叁数的方法很简单，只要输入当前绕取的细纱是多少支数（ Ne, Nm, Tex)如：Ne 40，然後输入想切除的偏粗、偏细细纱支数，例如：Ne 35, Ne 45，控制相就会自动算出直径偏差百分比，以这百分比当成错支清除门槛。

■ 注意
本传感器对可见光不敏感，无需再加滤光片； 中心孔为紫外线透射感应窗，请勿用任何物质遮盖，包括透明玻璃、塑胶片等； 如需清洁窗口，不能用酒精等溶剂类液体，请用棉棒醮清水轻轻擦拭。 安装时，不同的光线入射角度会有不同强度的信号输出，光线垂直入射时信号最强（电压输出数据为此 条件测得）。 由于周围物体反射的原因，人体实际所受紫外线辐射的强度比传感器测得的强度要高。

Applications:Features:TGS 825 - Special Sensor for Hydrogen Sulfide
* Hydrogen sulfide detectors/alarms* High sensitivity to low concentration of
hydrogen sulfide* Good repeatability in measurement* Uses simple electrical circuit* Ceramic base resistant to severeenvironment
The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductorwhich has low conductivity in clean air. In the presence of a detectable gas,the sensor's conductivity increases depending on the gas concentration inthe air. A simple electrical circuit can convert the change in conductivity toan output signal which corresponds to the gas concentration.
The TGS 825 has high sensitivity to hydrogen sulfide. The sensor can detectconcentrations of hydrogen sulfide as low as 5ppm, making it ideal forapplication in gas leak detection.
The figure below represents typical sensitivity char-acteristics, all data having been gathered at standardtest conditions (see reverse side of this sheet). The Y-axisis indicated as sensor resistance ratio (Rs/Ro) which isdefined as follows:Rs = Sensor resistance of displayed gases atvariousconcentrationsRo = Sensor resistance at 50ppm of hydrogenThe figure below represents typical temperature andhumidity dependency characteristics. Again, the Y-axis isindicated as sensor resistance ratio (Rs/Ro), defined asfollows:Rs = Sensor resistance at 50ppm of hydrogensulfide at various temp./humiditiesRo = Sensor resistance at 50ppm of hydrogensulfide at 20°C and 65% R.H.
