PT-104铂电阻数据记录仪PT-104是一种四通道温度测量数据记录仪。它提供***的分辨率(0.001°C)和精度(0.01°C)。它也可以测量电阻和电压。测量温度,电阻和电压高分辨率和高精度使用于PT100和PT1000传感器支持2，3和4线传感器不需要外部电源USB和Ethernet接口在单台PC上可运行多个记录仪精度和分辨率虽然***的温度传感器有很多种，但是很难发挥它们的优势，因为测量装置造成的错误。但是PT104本来就很***因为它的创新设计。不是根据电压参照(它倾向于温度灵敏度)，它采用"参照电阻"，这种电阻特别稳定(温度系数和漂移低)。每个电阻的准确值被存储在EEPROM内来提供***的精度(建议每年做校准)。一台高性能的24位数据记录仪可实现0.001°C的分辨率。PT-104螺钉端子适配器ThePT-104ScrewTerminalAdapterisanaccessoryforthePT-104PlatinumResistanceDataLogger.TheadapterallowsPT100probesthatarenotfittedwithamini-DINconnectortobeusedwiththedataloggerwithouttheneedforanysoldering.Theadapterissuitableforusewiththefollowingsizeofwire:2.5mm2solid1.5mm2stranded14-22AWG温度PT104使用铂电阻温度计(PRTs)测量温度。支持常规工业标准(PT100和PT1000)。该模块兼容2，3和4线传感器(推荐使用4线PT100传感器用于***测量)。PT-104温度记录仪可用各种PT100传感器。电阻当测量电阻时，你的PT-104使用一个4线电路来实现***大可能的精度。有两个电阻量程(0到375欧姆和0到10,000欧姆)。该模块校准于0到375欧姆，所以该量程应该用于***测量。电压对于电压测量，每个输入连接器可以做成差分输入带地极，或者两个单端输入。这两种输入都必须在零伏或以上，但是哪个输入电压更高不重要。有两个电压量程0到115mV和0到2500mV。对于大多数***测量，使用0到2500mV量程。软件PT-104数据记录仪包含PicoLog数据记录软件。PicoLog将自动探测哪个传感器被连接并且将以正确的单位显示读数。也提供软件开发包。包含各种软件驱动和例程代码，你可以写自己的软件或者把第三方软件用于你的PT-104数据记录仪。ButIneedtomeasuremorechannels…YourPT-104iscapableofmeasuringupto4channelsatonce.Needmorechannels?Noproblem.UsingPicoLogyoucanconnectupto10PT-104stoonePC—givingyouapotential40-channelPT100datalogger.AlternativelyyoucanuseyourPT-104loggerwithupto19otherPicodataloggers,suchasthePicoLog1000multi-channeldatalogger,tocreateyourowncustomdataacquisitionsystem.TheultimateinportabilityWithbothUSBandEthernetinterfacesyourPT-104canbeusedinavarietyofsituati***.Ifyouneedaportablesolutionthatcanbeusedatvariouslocati***andisfasttosetupanduse,simplyconnectyourlaptoptothePT-104byUSB.Needtomonitorasituationoveraperiodofhoursordays,orfromaremotelocation?PlugyourPT-104intoaspareportonyournetworkandthenaccessitremotelyeitherfromyourLANorovertheinternet(usingPoweroverEthernet(PoE)technologymeansthatyoudon’tevenneedaseparatepowersupply).WhenaccuracyisparamountthePT-104iswhatyouneedThePT-104platinumresistancedataloggergivesyoutheultimateinresolutionandaccuracy.Youcanuseittomeasuretemperature,voltageandresistance.H***ingbothUSBandEthernetinterfacesgivesyouthechoiceofhowyouconnectandpoweryourPT-104,alongwiththeabilitytoaccessthePT-104remotelyoveraLANortheinternet.WhentheaccuracyofyourtemperaturemeasurementsisparamountthePT-104iswhatyouneed.PT-104参数输入/输出温度电阻电压传感器PT100,PT1000N/AN/A范围-200到800°C0到375Ω0到10kΩ0到115mV0到2.5V线性20ppm精度@25°C0.01°C20ppm0.2%(2.5V)温度系数5ppm/°C5ppm/°C100ppm/°CRMS噪音(用滤波器)0.01°C10ppm10ppm分辨率0.001°C1μΩ0.156μV转换时间每通道720mS每通道输入数4输入连接器4-pinminiDIN输入阻抗>1MΩ过电压保护&plu***n;30V输出USB和Ethernet转换器分辨率24位PC要求***小处理器:PentiumII处理器或者以上内存:64MiB(XP)/512MiB(Vista)/1GiB(Win7)***小操作系统:32或者64-bit版MicrosoftWindowsXPSP2,Vista或者Windows7端口:USB2.0兼容口建议处理器:2GHzPentiumIV处理器或者同级内存:256MiB(XP)/1GiB(Vista/Win7)操作系统:32或者64-bit版MicrosoftWindowsXPSP2(或者以上),Vista或者Windows7端口:USB2.0兼容口环境工作环境温度范围湿度0°C至70°C(20°C至30°C用于标称精度)20至90%RH,非冷凝存放环境温度范围湿度-20至+80°C5至95%RH,非冷凝PhysicalDimensi***Dimensi***184x135x36mm(approx5.31x7.24x1.42in)Weight350g(approx12.3oz)SoftwarePicoLogforWindowsPicoLogdataacqusitionsoftwarecancollectupto1millionsamples.Featuresinclude:Multipleviews-viewdataasagraph,spreadsheetortextParameterscaling-convertrawdataintostandardengineeringunitsMathfuncti***-usemathematicalequati***tocalculateadditionalparametersAlarmlimits-programanalertifaparametergoesoutofaspecifiedrangeIPnetworking-transfermeasurementsviaaLANorovertheInternetFulldetailsonPicoLogSoftwaredevelopmentkitAgrowingcollectionofdriversandexamplecodeforvariousprogramminglanguagesLanguagesupportSoftwarePicoLogFullsupportforEnglish,FrenchandGerman;menusonlyforItalian,SpanishandSwedishDocumentationUser’sguideProgrammer’sguideEnglish,French,German,Italian,SpanishEnglishGeneralAdditionalha***are(supplied)USB2.0cable,Ethernetcable,usermanuals,softwareCD-ROMPCinterfaceUSB2.0(USB1.1compatible)orEthernet(cablessupplied)PowerrequirementsPoweredfromUSBportorEthernetComplianceFCC(EMC),CE(EMCandLVD),RoHScompliantTotalSatisfactionGuaranteeIntheeventthatthisproductdoesnotfullymeetyourrequirementsyoucanreturnitforanexchangeorrefund.Toclaim,theproductmustbereturnedingoodconditionwithin14days.Warranty5years)
