AMC910臺(tái)式過程壓力校準(zhǔn)儀提供了一個(gè)*獨(dú)立的測(cè)試通道，用戶可以通過它校驗(yàn)過程儀表和信號(hào)隔離器。事實(shí)上，這就像一臺(tái)二合一功能的儀器。AMC910臺(tái)式過程壓力校準(zhǔn)儀這個(gè)通道內(nèi)置了24VDC回路電壓和HART標(biāo)準(zhǔn)電阻，可以直接為2線制變送器供電以及連接基于HART通訊協(xié)議的儀表。
AMC910除了能夠提供溫度和壓力的校準(zhǔn)功能之外，更整合了電流和電壓的輸出、毫伏和電阻的測(cè)量。由于具備了另一個(gè)完整獨(dú)立的測(cè)試通道，使得AMC910成為實(shí)驗(yàn)室產(chǎn)品中的產(chǎn)品。多種校準(zhǔn)功能集聚一身的AMC910能夠勝任從實(shí)驗(yàn)室到現(xiàn)場(chǎng)的任何校準(zhǔn)任務(wù)。JOFRA AMC910能夠存儲(chǔ)zui多9個(gè)輸出信號(hào)的設(shè)定點(diǎn)。這些設(shè)定點(diǎn)能夠按照一定的時(shí)間間隔自動(dòng)或者手動(dòng)地步進(jìn)輸出。AMC910更具備了直觀、簡(jiǎn)便的操作界面以及通過RS232或者IEEE-488連接電腦進(jìn)行自動(dòng)校準(zhǔn)的功能。AMC910的電壓和電流源輸出功能也涵蓋了對(duì)多種設(shè)備的校準(zhǔn)功能，包括數(shù)據(jù)采集器、紙帶記錄儀、萬用表、手持式校準(zhǔn)儀和其他一些儀表設(shè)備。
在技術(shù)方面和商業(yè)領(lǐng)域，阿美特克校準(zhǔn)儀器（JOFRA）均是的溫度、壓力、過程信號(hào)校準(zhǔn)儀以及溫度傳感器的生產(chǎn)和研發(fā)廠家之一.阿美特克校準(zhǔn)儀器部在美國(guó)和丹麥分別設(shè)有工廠，專業(yè)生產(chǎn)和銷售系列JOFRA壓力校準(zhǔn)儀、干體式溫度校準(zhǔn)儀，電信號(hào)校準(zhǔn)儀等，應(yīng)用于工業(yè)現(xiàn)場(chǎng)以及實(shí)驗(yàn)室，是世界的校準(zhǔn)儀器專業(yè)生產(chǎn)廠家。發(fā)明了世界上*臺(tái)干體式溫度校準(zhǔn)儀。
