本特利990振動(dòng)變送器明星產(chǎn)品
KM990軸振動(dòng)變送器直接和電渦流傳感器探頭相連，中間不需前置器調(diào)理器，直接輸出工業(yè)標(biāo)準(zhǔn)的4-20mA電流信號可直接接入DCS或其他相關(guān)系統(tǒng)。

一、主要功能
■信號輸入、輸出全隔離，抗力強(qiáng)。
■間隙輸出(GAP.COM):指示被測體靜止和動(dòng)態(tài)是的位置狀態(tài),間隙電壓-2VDC～-18VDC。
■對應(yīng)振動(dòng)信號0~F（um），輸出4～20mA
■信號調(diào)理器電源:24VDC±10%，紋波小于10mv。

二、主要技術(shù)指標(biāo)
■傳感器輸入：KM1100系列電渦流傳感器
■軸振傳感器輸入點(diǎn)數(shù)：2個(gè)點(diǎn)
■系統(tǒng)輸入/輸出轉(zhuǎn)換精度（含傳感器）：
■記錄輸出：優(yōu)于±1.0%（全量程）0~65℃
■顯示：優(yōu)于±1.0%（全量程）0~65℃
■量程:0～125um
■輸出：標(biāo)準(zhǔn)信號:4～20mA;
■電源管理：每一個(gè)信號調(diào)理器電源獨(dú)立工作，互不影響。
■安裝方式：標(biāo)準(zhǔn)35mm導(dǎo)軌安裝或螺釘安裝
