Specifications and Ordering InformationPart Number 141610-01Rev. H (08/14)Bently Nevada* Asset Condition Monitoring31000 and 32000 Proximity Probe HousingsDescriptionThe 31000/32000 Proximity Probe Housing Assemblies are recommended when mounting proximity probes through the machine case and are typically used for radially mounted transducers, whether vibration or Keyphasor* measurements.Notes:1.When using these housings to measure radial vibration, ensure that the machine casing is affixed to the bearing in order to get an accurate relative vibration signal.2.When measuring shaft axial position with dual proximity probes, use housing 21022 instead. Consult specifications and ordering information (p/n 141601-01).Use of a Proximity probe housing allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacementwithout disassembly of the machine. The 31000/32000 Proximity Probe Housing Assembly is made of polyphenylene sulfide (PPS), an advanced, high-strength, thermoplastic with excellent corrosion resistance. Other elements of the housing assembly are made of corrosion-resistant stainless steel. The housing can be ordered with installed 3300 XL Proximity Probes and a variety of conduit fittings. The 31000/32000 Proximity Probe Housing Assembly is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.When installed in conjunction with an approved transducer system andappropriate I.S. barriers, the 31000/32000 Proximity Probe Housing Assembly can be used in intrinsically safe hazardous area applications.Note: The 31000/32000 Housing is intended to provide mechanical and environmental protection only, and is not an explosion-proof housing. When an explosion proof proximity probe housing assembly is required, use housing CA21000 or CA24701. Consult specifications and ordering information (p/n 141600-01).SpecificationsMechanicalProtectionRatings:Type 4X rating certified byCanadian Standards Association(CSA).

Environmental LimitsTemperatureRating:-51°C to +105°C (-60°F to +221°F)Hot Water and SteamExposure Effects:(Specification not guaranteed)Brief periods (up to one week) ofcontact with hot water (95°C[203°F]) and/or condensing steamshould not significantly affect thestrength of the plastic housing.Contact with these beyond thislength of time may eventuallycause the strength of the plastichousing to permanently decreaseduring the first 6 to 8 weeks ofexposure, and then level atapproximately half of its initialvalue. Tests of actual housingperformance after contact withhot water and condensing steamhave not been conducted.Probe PressureThe 31000/32000 Proximity ProbeHousing Assembly is designed toseal differential pressure betweenthe probe tip and the housingmain body when used with a3300 XL 8 mm probe. The sealingmaterial internal to the probecase consists of a Viton® O-ring;the O-ring between the sleeveand the housing is a Neoprene®O-ring. The plastic housing iscertified to seal against hose-Specifications and Ordering Informationdirected water according toNEMA 4X and IP66 standards butis not designed to resist internalor external pressure. Probes arenot pressure tested prior toshipment. Contact our customdesign department if you requirea test of the pressure seal for yourapplication.Note: It is the responsibility of thecustomer or user to ensure that all liquidsand gases are contained and safelycontrolled should leakage occur from aProximity Probe Housing Assembly.Solutions with high or low pH values mayerode the tip assembly of the probe,causing media leakage into surroundingareas.

比表面积孔径分析仪安全操作及保养规程前言比表面积孔径分析仪是一种常见的测量技术，主要用于分析固体和液体材料的表面积和孔径大小。

为了保证设备正常运行并确保操作人员和环境的安全，需要遵循以下的安全操作和保养规程。

安全操作1. 设备检查在使用比表面积孔径分析仪之前, 需要进行设备检查以确保设备正常运行。

具体操作步骤如下：•检查电缆和接插件是否完好无损,接地是否牢固;•检查设备内部是否有异常杂音或其他异常声响;•检查各个零部件是否整齐、完好;•检查仪器面板是否有显示错误。

2. 操作前准备在启动比表面积孔径分析仪之前需要准备好以下物品：•样品•样品操作手册•手套、口罩和护目镜等必要的防护用品并且需要根据样品大小和形态，选择适当的检测配置，并且对设备的各项参数进行调整和优化。

3. 操作过程在使用比表面积孔径分析仪时，需要注意以下操作：•操作过程中，不能揭开仪器的机箱或停止仪器正在进行的检测操作。

这样会破坏仪器的内部环境，也可能影响检测结果的准确性。

•操作时必须佩戴手套、口罩和护目镜等防护用品，避免样品或者其他化学品对操作人员的危害威胁。

•每次操作完成后应当关机，及时清理设备内部，彻底清除样品残余物，以避免样品受到污染。

4. 故障排除如果设备发生故障，应当根据以下步骤进行排查和修复：1.首先检查并修复电源和电缆故障。

2.随后检查仪器是否有因长期使用而导致的老化损坏或电器元件损坏等问题，及时更换或送修。

3.如果有其他的故障，则应当联系仪器的维修人员进行维修和处理。

设备保养除了在正常操作过程中需要执行的预防性维护外，对于比表面积孔径分析仪需要进行定期维修,以保障设备的长期运行能力，并及时处理一些潜在的故障。

1.日常维护在平时使用中，需要进行以下的日常维护：1.使用干净的布或静电毛刷清理仪器表面，并定期检查电缆连接是否紧固；2.定期（每月或每季度）检查内部附件是否干净、运转正常，并根据维护手册记录进行保养；3.定期更换和清洗滤芯，并按照景泰规定的要求校验和校准分析仪所用的计量器具。

ASAP2020M比表面及孔径分析仪的操作指南一样品及试管准备1 样品上机分析前的预处理1) 样品应放置在高温烘箱中，至少在110 度下烘干2 小时，若能放置在真空烘箱中烘干效果更好，样品自然冷却至室温，并在干燥器皿中保存。

2) 对于密度小的粉末样品，尽量在 20 公斤力下先压片。

2 清洗和标识样品管1) 首先用少量去污粉和专用毛刷清洗因管内部。

2) 用蒸馏水或去离子水清洗样品管。

3) 用酒精或丙酮清洗样品管。

4) 烘箱设定 110 度2小时烘干。

5) 待烘箱降温至室温后，取出样品管和填充棒。

将塞子用干净的绸布擦净，安装在样品管上。

6) 对样品管和塞子，进行标识。

注意：由于石英样品管在接下来的实验中要放在高温的炉子里，管子表面的任何油渍会损害石英管，所以不能用裸露的手直接触摸样品管表面。

二称量样品质量1) 在记录本上记录样品管号。

2) 将托放在天平上后归零。

3) 将样品管组件（样品管，塞子，填充棒）连同托放在天平上称重，并记录样品管的空管重量。

4) 把盛样品的容器放在天平上归零。

5) 慢慢将样品放入盛样品的容器中，称重，此时为粗称样品质量。

6）取下样品管塞子，从样品管内取出填充棒。

7）使用漏斗、长颈漏斗，装入样品，尽可能少沾污管壁。

8）重新放入填充棒并加上塞子。

9）待脱气完成后重新称量含样品的样品管组件，并记录总重量，减去之前记录的空管重量，便获得样品净重。

三软件使用-新建文件1在桌面上点击“ASAP 2020”图标，进入仪器软件系统2 新建文件1）在主菜单中，选择文件 File，打开Open，点击样品信息文件Sample Information 2）将出现样品信息文件对话窗口。

在文件名称File name栏目，建立新的文件名称（仅8位数字或字母，本测试中心使用“09101301”，前六位为日期，后两位数字区别）。

点击 OK，出现左下侧提示信息，点击Yes, 便产生了新文件，并出现样品信息对话窗口。

岛津UV-3600／3100紫外近红外积分球的使用和维护宋萍【摘要】Integrating sphere is a very significant attachment of UV-VIS-NIR spectrophotometer. This paper focused on Shimadzu UV-3600/3100 Series ,introduced the appiication of UV-VIS-NIR integrating sphere attachent in transmittance and reflectance test .%积分球是紫外近红外分光光度计的重要组件，本文以岛津UV-3600/3100紫外近红外积分球为例，介绍了该积分球在测试样品透过率及反射率的使用方法及日常维护。

【期刊名称】《分析仪器》【年(卷),期】2014(000)004【总页数】3页(P124-126)【关键词】积分球;使用;维护【作者】宋萍【作者单位】苏州大学分析测试中心，苏州 215123【正文语种】中文积分球（integrating sphere）是内层涂有高反射材料的空心球体，通常也被称为光通球，光度球。

积分球的历史最早可以追溯到1890年，现已被广泛应用于光学、化学、物理、材料测试中，是测试辐射度、光通量和色度必不可少的元件之一［1］。

积分球的主要作用是通过漫反射对样品信号进行匀光，光通过样品后产生的各向异性的光束在积分球腔体内进行全方位的漫反射，被平均后的样品光信号被光电倍增管经一步放大而被检测［2］。

由于光源的形状大小不同，加之电压的上下波动导致光源发出的光不可能是完全均匀的一束光。

而光的不均匀性会对测试的辐射度、广度、亮度结果造成影响，因此积分球的使用克服了传统的用光电倍增管直接作为检测器的缺点，即结果不受样品光束形状的影响，最终使得测试结果更为可靠精确［3］。

积分球常见的是用氧化镁、硫酸钡或聚四氟乙烯悬浮树脂做内层涂料。
