IOtech 600系列提供配有USB或以太網(wǎng)接口的24位動態(tài)信號分析儀,,在提供最大靈活性的同時,,將采集的數(shù)據(jù)實時傳輸至PC。動態(tài)信號采集(DSA)硬件提供信號調(diào)理和數(shù)據(jù)采集,;基于PC的eZ-Series軟件提供監(jiān)測和分析函數(shù),。
用戶可將600系列用于多類模擬輸入(包括:加速度計、速度計、接近式探針,、麥克風(fēng),、轉(zhuǎn)速表或其他電壓輸入)。640型號可接受達(dá)±10 V輸入,;650,、652和672型號可接受達(dá)±40 V輸入。600系列還支持軟件可選式交流或直流耦合,,當(dāng)與集成電路壓電式(IEPE)傳感器連接并配置為交流耦合時,,還能自動提供2.1 mA(640、650)或4 mA(652u,、672u)的激勵電流源,。
640型號包含1路可編程模擬輸出通道,可生成連續(xù)或掃頻正弦波信號以及隨機,、突發(fā)和任意信號,。模擬輸出信號可用于驅(qū)動音頻或振動臺放大器,繼而實現(xiàn)噪聲,、振動和聲振粗糙度(NVH)測試,。
多種600系列軟件包(如:eZ-TOMAS和eZ-Balance)專門針對特定的振動測量和分析應(yīng)用。
eZ-TOMAS和eZ-TOMAS Remote中極其完善且易于使用的工具適合單個或多個機器的監(jiān)測與分析,。它們可用來評估可靠性和操作性,。
通過eZ-Balance能夠完成最多7個平面的旋轉(zhuǎn)機械動平衡。平衡套件包含分離質(zhì)量計算,,有助平衡處理,。eZ-Balance只兼容640u、650u,、652u和ZonicBook/618E動態(tài)信號分析儀,。
另外北京迪陽公司還提供一套可與IOtech DSA硬件搭配的振動傳感器。LCO103T
