一、產(chǎn)品概述：

振動速度傳感器主要安裝在各種旋轉(zhuǎn)機(jī)械裝置的軸承蓋上（如汽輪機(jī)、壓縮機(jī)、風(fēng)機(jī)和泵等）的傳感器。它主要由磁路系統(tǒng)、線圈組件、彈簧阻尼等部分組成。在傳感器殼體中剛性地固定有兩個線圈組件，磁鋼用彈簧懸掛于殼體。當(dāng)傳感器在工作頻率范圍內(nèi)工作時，線圈與磁鋼產(chǎn)生相對運(yùn)動，線圈切割磁力線，產(chǎn)生感應(yīng)電動勢（感應(yīng)電壓），該電壓正比于機(jī)殼的振動速度，提供信號輸送給監(jiān)測儀表，用來對機(jī)械故障進(jìn)行預(yù)測和報警。傳感器具有工作時不需要供給電源、安裝方便，耐高溫等特點(diǎn)。
