德國(guó)科恩天平的發(fā)展史
- 科恩公司簡(jiǎn)介及發(fā)展史德國(guó)科恩(KERN)公司成立于1844年,起初以工業(yè)天平起家,是德國(guó)南部一家正規(guī)注冊(cè)的獨(dú)立家族企業(yè),168年來(lái)經(jīng)過(guò)六代人不斷的研發(fā)與傳承,現(xiàn)在科恩已經(jīng)通過(guò)了DINISO9001:2000認(rèn)證,并且成為了質(zhì)量可靠與服務(wù)可靠的代名詞,成為了稱(chēng)量領(lǐng)域的專(zhuān)家,其應(yīng)用在不同領(lǐng)域的廣闊生產(chǎn)線,不斷地滿(mǎn)足著客戶(hù)對(duì)應(yīng)用的要求??贫魍ㄟ^(guò)十幾年的研發(fā)與積累于1844年制造出了當(dāng)時(shí)世界上Z為精密的天平,使其一躍成為當(dāng)時(shí)德國(guó)以及國(guó)際上Z的天平制造業(yè)的核心;1880年,引進(jìn)了沖壓工藝制造了醫(yī)藥天平,其技術(shù)**于世界其他品牌;此后的100年間,科恩不斷地研發(fā)新的產(chǎn)品以及新的制造工藝,在歐洲逐漸確立了自己在同行業(yè)中的地位,并于1980年制造出了**臺(tái)屬于科恩自己的電子天平;1994年,科恩的實(shí)驗(yàn)室獲得了德國(guó)校準(zhǔn)認(rèn)可機(jī)構(gòu)的認(rèn)可,并成功通過(guò)DKD(ISO17025)認(rèn)證;2000年,由于品牌、市場(chǎng)及影響力的不斷擴(kuò)大,在德國(guó)巴林根建造了新的廠房;2002年,科恩通過(guò)了德國(guó)DQS管理體系頒發(fā)的管理體系認(rèn)證(DINENISO9001:2000);2007年,獲得歐盟批準(zhǔn)YL器械生產(chǎn)許可(DINEN13485和93/42/EEC),從而為科恩開(kāi)拓YL產(chǎn)品市場(chǎng)打下了堅(jiān)實(shí)的基礎(chǔ);2008年,獲得歐盟稱(chēng)重設(shè)備認(rèn)證(90/384/EEC)??贫鲗?duì)產(chǎn)品品質(zhì)的熱情投入使其成為稱(chēng)量?jī)x器領(lǐng)域的專(zhuān)家,是目前僅有的三家通過(guò)DKD認(rèn)證的衡器生廠商之一,象征著準(zhǔn)確性和可靠性??贫魇呛馄黝I(lǐng)域里極ng確和可信賴(lài)的標(biāo)志。DKD認(rèn)證DKD是德國(guó)校準(zhǔn)認(rèn)可機(jī)構(gòu)的簡(jiǎn)稱(chēng),是歐洲認(rèn)可合作組織成員(EuropeanCooperationforAccreditaion,EA)。它是由企業(yè)、科研機(jī)構(gòu)和技術(shù)主管單位的校準(zhǔn)實(shí)驗(yàn)室一季檢測(cè)檢驗(yàn)機(jī)構(gòu)等共同體組成,并且統(tǒng)一受德國(guó)校準(zhǔn)服務(wù)局的監(jiān)督機(jī)構(gòu)監(jiān)管。其職責(zé)為嚴(yán)格按照檢測(cè)機(jī)構(gòu)給定的測(cè)量標(biāo)準(zhǔn)和尺寸對(duì)技術(shù)設(shè)備和檢測(cè)儀器進(jìn)行標(biāo)定。2000年10月,超過(guò)40個(gè)國(guó)家的50多個(gè)認(rèn)證實(shí)體簽署了**個(gè)相互認(rèn)可的國(guó)際公約,暨國(guó)際實(shí)驗(yàn)室認(rèn)證合作組織(ILAC)的《多邊認(rèn)證協(xié)定》(MutualRecognitionArrangement,MRA)。在這個(gè)公約下,簽署各方同意相互認(rèn)可并促進(jìn)接受簽發(fā)方簽發(fā)的校準(zhǔn)認(rèn)證及檢測(cè)報(bào)告。如DINENISO9001與ISO/IEC17025對(duì)計(jì)量?jī)x器監(jiān)測(cè)的要求,DKD校準(zhǔn)認(rèn)證證書(shū)正是記錄了根據(jù)國(guó)家以及國(guó)際標(biāo)準(zhǔn)進(jìn)行測(cè)試結(jié)果的可追溯性。工廠校準(zhǔn)服務(wù)于DKD校準(zhǔn)服務(wù)的主要區(qū)別是,DKD授權(quán)實(shí)驗(yàn)室承諾的對(duì)于相應(yīng)測(cè)試的不確定度的判定準(zhǔn)確性要高于普通校準(zhǔn)服務(wù)。DKD校準(zhǔn)認(rèn)證證書(shū)適用于任何需要認(rèn)證的實(shí)驗(yàn)室,這些實(shí)驗(yàn)室往往需要高要求的校準(zhǔn)并將此作為平行檢測(cè)的參照標(biāo)準(zhǔn)。DKD實(shí)驗(yàn)室為所有的科恩測(cè)量?jī)x器的精度提供了無(wú)懈可擊的保證。同時(shí),科恩的工程師在柏林布魯塞爾的專(zhuān)家委員會(huì)參與制定測(cè)量規(guī)范的工作,他們是測(cè)量工藝的代表,在行業(yè)界受到極高的尊重。憑借多年積累的豐富測(cè)量經(jīng)驗(yàn)和獨(dú)到的解決方案,以及精湛的測(cè)量技術(shù),科恩其自設(shè)的DKD實(shí)驗(yàn)室已成功為企業(yè)各級(jí)標(biāo)準(zhǔn)實(shí)驗(yàn)室提供Z專(zhuān)業(yè)的測(cè)量及校準(zhǔn)服務(wù)。經(jīng)過(guò)DKD-校準(zhǔn)實(shí)驗(yàn)室標(biāo)定校準(zhǔn)后的產(chǎn)品有效地保障了用戶(hù)所使用儀器的準(zhǔn)確性。從而增強(qiáng)用戶(hù)的信心和其產(chǎn)品在國(guó)內(nèi)外市場(chǎng)的競(jìng)爭(zhēng)能力。從質(zhì)量管理的角度來(lái)講,又是監(jiān)控測(cè)量和檢測(cè)手段的基礎(chǔ)。事實(shí)上,科恩產(chǎn)品經(jīng)過(guò)多年的考驗(yàn)和充實(shí),早已被國(guó)內(nèi)外各大研究機(jī)構(gòu)、各實(shí)驗(yàn)室、環(huán)保及節(jié)能監(jiān)測(cè)機(jī)構(gòu)采用,并成為包括IBM、英特爾(INTEL)、AT&T等眾多國(guó)際企業(yè)指定優(yōu)先選用的檢測(cè)設(shè)備,同時(shí)贏得包括德、美、日、韓、法,包括ZG在內(nèi)各國(guó)家實(shí)驗(yàn)室的全程認(rèn)可,以及歐盟(EU)和ISO9001的國(guó)際認(rèn)可。[詳細(xì)]

- MOOG穆格公司成立于五十多年前,Z初從事飛機(jī)與部件的設(shè)計(jì)及供應(yīng)。如今,本公司的運(yùn)動(dòng)控制技術(shù)廣泛應(yīng)用于民用機(jī)座艙、發(fā)電風(fēng)機(jī)、一級(jí)方程式賽車(chē)、醫(yī)用輸液系統(tǒng)等眾多的市場(chǎng)和應(yīng)用領(lǐng)域,有效提高相關(guān)產(chǎn)品的性能。該公司歷史起源于公司創(chuàng)建者威廉C穆格,他是一位發(fā)明家、企業(yè)家,也是一位遠(yuǎn)見(jiàn)卓識(shí)者。1951年,比爾穆格研制成功電液伺服閥,這種裝置可把微弱的電脈沖轉(zhuǎn)換為極ng確而有力的運(yùn)動(dòng)。1951年7月,比爾穆格、阿特兄弟倆和盧蓋耶在紐約州東奧羅拉租借了已廢棄的Proner機(jī)場(chǎng)的一角,成立了穆格制閥公司(MOOGValveCompany)。穆格MOOG公司是設(shè)計(jì),制造和精密運(yùn)動(dòng)控制產(chǎn)品和系統(tǒng)集成商。穆格的高性能系統(tǒng)的控制和商用飛機(jī),衛(wèi)星和航天器,運(yùn)載火箭,,工業(yè)機(jī)械,風(fēng)能,海洋應(yīng)用和YL設(shè)備.MOOG分類(lèi)MOOG閥,MOOG伺服閥、MOOG伺服電機(jī)、MOOG控制器、MOOG伺服驅(qū)動(dòng)器,MOOG電液伺服閥,MOOG柱塞泵穆格的首批訂單**份訂單是來(lái)自BendixAviation公司的制造四個(gè)閥門(mén)的訂單。隨后是來(lái)自波音公司和Convair公司的較大訂單。伺服閥給航天航空業(yè)帶來(lái)了一場(chǎng)變革,并促成了穆格公司(MoogInc.)的建立。到了1954年,穆格公司的閥門(mén)已成為美國(guó)半數(shù)以上殲擊機(jī)和超過(guò)70%上使用的標(biāo)準(zhǔn)設(shè)備。公司還成功推出了工業(yè)閥門(mén),到了1960年,總銷(xiāo)售額已增長(zhǎng)至一千多萬(wàn)美元。在本公司Z自豪的航天航空領(lǐng)域,我們的工程師設(shè)計(jì)并制造了土星C-5火箭的作動(dòng)器,正是該型火箭于1969年7月將尼爾阿姆斯特朗送上了太空,在月球上邁出了歷史性的**步。20世紀(jì)70年代至90年代:持續(xù)增長(zhǎng)20世紀(jì)70年代,本公司進(jìn)入了成長(zhǎng)中的注塑與吹塑成形工藝控制技術(shù)市場(chǎng)。由于公司較多地參與了美國(guó)的太空計(jì)劃,因此贏得了航天飛機(jī)硬件供貨合同。航天飛機(jī)于1981年首飛,S次應(yīng)用了本公司開(kāi)創(chuàng)性的電傳控制技術(shù)。1988年,本公司飛機(jī)部門(mén)總裁RobertT.Brady被任命為首席執(zhí)行官。1989年的銷(xiāo)售額達(dá)到了2.82億美元。本公司于上世紀(jì)90年代中期在印度建立了業(yè)務(wù)。我們的S次大規(guī)模收購(gòu)是從AlliedSignal公司購(gòu)買(mǎi)了后者位于加利福尼亞州托蘭斯的飛機(jī)業(yè)務(wù)。到1999年底,公司收入超過(guò)了6.30億美元。Z近的成功案例2001年,本公司獲得了一份五千萬(wàn)美元的航天飛機(jī)翻新合同,并且公司股票從美國(guó)證交所轉(zhuǎn)到了紐約證交所。我們是洛克希德公司生產(chǎn)的F-35型戰(zhàn)機(jī)的飛行控制系統(tǒng)指定設(shè)計(jì)商及供應(yīng)商,并且是波音公司787“夢(mèng)想飛機(jī)“計(jì)劃主要飛行控制部件的提供商。2004年,公司收入突破9億美元大關(guān),完成了又一次大規(guī)模并購(gòu),收購(gòu)了LittonPoly-Scientific公司,并將其命名為穆格部件集團(tuán)(MoogComponentsGroup)。公司財(cái)年銷(xiāo)售額S次突破10億美元。穆格:創(chuàng)新的環(huán)境比爾穆格的創(chuàng)新感遠(yuǎn)不限于產(chǎn)品設(shè)計(jì)。他從一開(kāi)始就堅(jiān)信工作場(chǎng)所應(yīng)該是一個(gè)很特殊的地方。他相信:人們?cè)谝粋€(gè)得到信任、尊重和回報(bào)的工作環(huán)境中,會(huì)更有創(chuàng)造力、更專(zhuān)注、更有工作效率。這一套思想就是日后人們熟知的“穆格理念”。這套原則即便在今天也在引領(lǐng)著本公司前進(jìn)?!霸谝粋€(gè)彼此信任、彼此有信心的氛圍中,工作對(duì)于所有人都會(huì)是一種回報(bào)更多、更令人滿(mǎn)足的體驗(yàn)?!盉obBrady在公司的《2006年報(bào)》中寫(xiě)道:“本公司Z重要的屬性就是公司文化,它將我們的人員團(tuán)結(jié)起來(lái),并為他們提供了動(dòng)力。這種文化基于正直、誠(chéng)信和互信。它重視工作能力、非凡的努力、個(gè)人責(zé)任、協(xié)作關(guān)系和開(kāi)放式溝通。正是它把Zyou秀的人才吸引并留在本公司。在這種環(huán)境中,他們可以做出**的工作成績(jī)。了解本公司人員的客戶(hù)都知道:他們將竭盡全力履行本公司的承諾。倘若穆格公司的一位員工做出了一項(xiàng)許諾,那么公司將信守許諾?!北竟緩氖贾两K深信:只有當(dāng)人們?cè)谝粋€(gè)環(huán)境中感到自己受重視,有充分的參與機(jī)會(huì),并且被賦予履行職責(zé)的權(quán)利時(shí),他們才會(huì)有**工作表現(xiàn)。而其它公司才剛剛發(fā)現(xiàn)這點(diǎn)。正如比爾穆格曾說(shuō):“我們相信在這里工作的人們……我們知道的**可行方式就是讓人們彼此信任并充滿(mǎn)信心。”作為一個(gè)十分成功的企業(yè),穆格的基石是一群努力工作、才華出眾、富有奉獻(xiàn)精神的人員。1997年秋季,比爾穆格與世長(zhǎng)辭。本公司董事長(zhǎng)兼首席執(zhí)行官BobBrady在比爾去世后不久所致的追悼辭中,對(duì)本公司做了如下描述:ServovalveswithintegratedElectronicsD791andD792Series23Q[l/min]=max.flowΔp[bar]=valvepressuredropwithQAK[cm2]=spooldriveareapX[bar]=pilotpressureThepilotpressurepXhastobeatleast15barabovethereturnpressureofthepilotstage.D791andD792SeriesThreestageservovalvesPrincipleofoperationAnelectricalcommandsignal(setpoint,inputsignal)isappliedtotheintegratedcontrolamplifierwhichdrivesacurrentthroughthepilotvalvecoils.Thepilotvalveproducesdifferentialpressureinitscontrolports.Thispressuredifferenceresultsinapilotflowwhichcausesmainspooldisplacement.Thepositiontransducerwhichisexcitedviaanoscillatormeasuresthepositionofthemainspool(actualvalue,positionvoltage).Thissignalthenisdemodulatedandfedbacktothecontrolamplifierwhereitiscomparedwiththecommandsignal.Thecontrolamplifierdrivesthepilotvalveuntiltheerrorbetweencommandsignalandfeedbacksignaliszero.Thus,thepositionofthemainspoolisproportionaltotheelectricalcommandsignal.QQppNN=ΔΔp2,510QAXp-2K≥ΔTheactualflowdependsontheelectricalcommandsignalandthevalvepressuredrop,andmaybecalculatedusingthesquarerootfunctionforasharp-edgedorifice.TheflowvalueQcalculatedinthisway首ldnotexceedanaverageflowvelocityof30m/sinportsP,A,BandT.Q[l/min]=calculatedflowQN[l/min]=ratedflowΔp[bar]=actualvalvepressuredropΔpN[bar]=ratedvalvepressuredropOperationalfeatures?Electricalpositionfeedbackwithpressureisolatedpositiontransducer(LVDT),nowear?IntegratedSMDelectronicswithfalsepolarityprotection?Optionalexternalpilotsupplyandreturnconnectionsviafifthandsixthportinvalvebody?Lowthresholdandhysteresis,excellentnullstability?Preadjustedatfactory4Iflargeflowrateswithhighvalvepressuredropsarerequired,anappropriatehigherpilotpressurehastobechosentoovercometheflowforces.Anapproximatevaluecanbecalculatedasfollows:ThevalvesD791andD792SeriesdescribedinthiscataloguehavesuccessfullypassedEMCtestsrequiredbyECDirective.Pleasetakenoticeoftherespectivereferencesintheelectronicssection.OurqualitymanagementsystemiscertifiedinaccordancewithDINENISO9001.Thiscatalogueisforuserswithtechnicalknowledge.Toensurethatallnecessarycharacteristicsforfunctionandsafetyofthesystemaregiven,theuserhastocheckthesuitabilityoftheproductsdescribedhere.IncaseofdoubtpleasecontactMoog.Th

近紅外光譜儀--響尾蛇?系列
- 響尾蛇?系列規(guī)格書(shū)
響尾蛇?(Sidewinder?, SW)系列 光譜儀是由 InGaAs 線型傳感器 加上 32bits RISC 微控制器組成,專(zhuān)門(mén)設(shè)計(jì)用于檢測(cè)近紅外光譜。擁有精簡(jiǎn)架構(gòu)及優(yōu)化之光譜分析核心。在光譜量測(cè)上,其光學(xué)架構(gòu)能提供提供十分堅(jiān)固及穩(wěn)定的量測(cè)性能,尤其是在分辨率及波長(zhǎng)飄移上有優(yōu)異的溫濕度、震動(dòng)、與撞擊穩(wěn)定性。微小化設(shè)計(jì)更是提供了各種系統(tǒng)整合之彈性。
SW系列光譜儀為 Czerny-Turner 光學(xué)設(shè)計(jì),提供高光學(xué)分辨率、高靈敏度、低雜散光、以及快速光譜反應(yīng)速度。SW系列光譜儀是由USB供電并藉由USB連接計(jì)算機(jī)。除此之外亦提供了6 I/Os 接口可用來(lái)接外部裝置。
SW系列光譜模塊使用高靈敏度 InGaAs 線型傳感器 。本規(guī)格書(shū)提供 SW系列 光譜儀相關(guān)的訊息及詳細(xì)的操作方式。SW系列光譜儀是藉由 RISC 微控制器進(jìn)行電子操作。使用者可藉由臺(tái)灣超微光學(xué)公司提供之計(jì)算機(jī)軟件控制。
