复合真空计说明书复合真空计是一种用于测量真空度的仪器,它由多个部件组成,包括压力传感器、控制器、显示器等。
本文将详细介绍复合真空计的原理、使用方法以及注意事项。
一、原理复合真空计的原理是基于热电效应和热导率的测量原理。
当真空度发生变化时,热电偶的电势差也会发生变化,通过测量电势差的变化,可以得出真空度的变化。
同时,复合真空计还可以通过测量热导率的变化来确定真空度。
二、使用方法1.准备工作在使用复合真空计之前,需要进行一些准备工作。
首先,需要将仪器放置在干燥、通风的地方,避免受潮或受到其他污染物的影响。
其次,需要将仪器的各个部件连接好,并将控制器和显示器连接到电源上。
2.校准仪器在使用复合真空计之前,需要对仪器进行校准。
校准的目的是确保仪器的测量结果准确可靠。
校准的方法是将仪器放置在已知真空度的环境中,然后根据测量结果进行调整。
3.测量真空度在进行测量时,需要将复合真空计放置在待测物体的附近,然后打开仪器的电源,等待一段时间,直到仪器的显示屏上显示出当前的真空度。
如果需要连续测量,可以将仪器连接到计算机上,通过软件进行数据记录和分析。
三、注意事项1.避免受潮复合真空计是一种精密仪器,需要避免受潮或受到其他污染物的影响。
在使用过程中,应该将仪器放置在干燥、通风的地方,避免受潮。

真空计使用方法1、天海、广汇、安瑞科贮罐规管须使用HASTING HPM4/6真空计测量,2、HPM 4/6真空计为便携式、数显,使用9VDC直流电池。
3、HPM4/6真空计测量范围有两个:0.001-1.0 Torr 和0.01-20.0 Torr左侧有一选择开关,放在中间是关的位置,往上推则是DV6的位置,即测量低温容器真空度的位置,测量范围为0.001-1.0 Torr。
只有当低温容器和低温罐车的真空度低于一个Torr时,真空计的液晶显示屏才能够显示低温容器和低温罐车的真空度;往下推则是DV4的位置,测量范围为0.01-20.0 Torr,对我们测量低温容器真空度用处不大。
故平时不要将选择开关往下推。
使用完毕后,将选择开关放在中间关的位置,以防电池电量短时间内耗尽。
当电池电量低时,液晶显示屏会显示“LOBAT”,这时显示的真空度不准确,应立即关机并更换9VDC直流电池。
4、注意真空计使用完毕后应及时放回黑色包装盒内,不受潮和强光照射,也不要暴露于灰尘之中,同时注意防止剧烈振动(如不能从高处摔到地上)。
5、测量步骤如下:图a图b提示:真空计价格昂贵,请您小心使用、注意保护,用后及时保存。
6、根据GB/T 18442常温下(储罐未进液)封结真空度:真空阀打开后等一小时,然后再测,只需要测一次,但如果真空度有问题的,需要再次确认,可等待一小时后再测一次,没有问题的只需要测一次就行了。
6.4.4 在低温使用过程中,缠绕储罐真空夹层的压力不高于0.015帕(0.00011 TORR)6.4.5 在低温使用过程中,珠光砂罐真空夹层的压力不高于0. 5帕 (0.00376 TORR) 6.4.6 质保期内,低温储罐加入低温液体后,罐体不应“出汗”但TSG R7001-2004中的要求很低:(一般厂家都用此要求)未装低温介质情况下,粉末罐真空度不大于65帕,缠绕罐不大于40帕装低温介质情况下,粉末罐真空度不大于10帕,缠绕罐不大于0.2帕。

真空度测试仪产品使用方法真空度测试仪产品使用方法真空度测试仪紧要用于用途检测安装于开关整机上的真空灭弧室的真空度(这类检测紧要用于供电部门的例行检修及容量试验中对真空灭弧室经受本领的判定)和真空灭弧室生产线中灭弧室的质量掌控,断路器生产厂家的灭弧室的入库检验。
真空度测试仪使用方法:连线将面板上的磁控电流输出端通过导线与磁控线圈相连,使灭弧室触头至于分状态(线圈套于灭弧室外),将高压线和信号输入线分别接灭弧室的动端与静端。
注意,高压线应悬空。
管型选择测量时,首先选择管型。
管型选择操作方式按[选择键],使指向选择测试管型,按[确认键],用〔+键〕或〔—键〕调整管型参数,当显示器显示管型与所需测量的管型全都时便可,按[确认键],返回主菜单。
若说明书中没有给出要测量的管型时,可用尺寸相近,接线方式相同的管型替换。
然后测量按[选择键]使[◢◢]至测试真空管“Pa”,按[确认键]仪器处于测量状态。
并自动完成全部的测量、计算、显示等全过程。
再者打印若需打印测试数据,则按[确认键]返回主菜单,按[选择键]使[◢◢]至打印测试数据,再按[打印键],即可打印出全部测量数据。
zui后,假如没有可代用的参数,则可按[选择键]使[◢◢]指向“A”,这样可直接给出电离电流,一般来说。
电离电流(A)较真空度(Pa)小2个数量级。
仪器内计算机执行测量步骤启动高压→测漏电电流→自动关闭高压,接通充电开关→电压到规定值→重新启动高压,同时启动磁控电流,测量漏电电流+电离漏电电流→扣除漏电电流→电流变动成真空度值→显示、打印。
若[测A键]有效,则显示电流值。
本仪器采用两次启动高压的方法,若仪器*次启动高压后又回到初始状态,此时为仪器拒检。
应检查真空管是否处于合的状态,如不是,则该管已严重漏气或*泄漏。

石英晶振装在铝壳中做成规管,管径为15.5mm,可通过接口插入系统。
谐振阻抗的测量电路如图1所示:图1 谐振阻抗测量电路谐振阻抗Z=V ABV AB 为晶振两端电压 I 为流过晶振的电流电流I 流过与晶振串联的电阻R ,在电阻两端的电压为V BD ∴ I =V BDZ=BDAB V V RV AB 近似等于AC 两端电压V 0,V BD 近似等于DC 两端电压V 1,由测量的V 0,V 1值及电阻值,可以计算出阻抗。
单片机将阻抗转换成压强,由数码管显示压强值。
四、 DL-10真空计的安装DL-10真空计的安装如图2所示:控制单元图2 DL-10 的安装石英晶振及振荡电路放在探头内,引线电缆通过5芯插头插入控制单元后面板的插座内,探头Φ15.5直径的管道插入真空系统。
电源电缆一头插入控制单元后面板插座,另一端插入电源插座。
电源插座应含接地线,使控制单元机箱接地。
打开电源开关,控制单元数码管显示压强值。
数码管显示3.2 E 2 表示压强值为3.2×102Pa 。
五、 校准当环境温度变化时,应对DL-10进行校准,校准方法如下:1、 大气校准:在规管压强为大气时,用改锥按压控制单元前面板大气孔内的按键,松开后即可。
2、 零点调节:在规管压强小于1×10-2Pa 时,用改锥按压控制单元前面板零点孔内的按键,松开后即可。
如果真空系统达不到1×10-2Pa ,不可按压零点按键。
