BENTLY振動(dòng)監(jiān)測(cè)器作為技防手段已逐步被人們認(rèn)識(shí)和應(yīng)用。
振動(dòng)監(jiān)測(cè)器是一種對(duì)重要設(shè)備的振動(dòng)頻率進(jìn)行高精度監(jiān)測(cè)的儀器。
該款產(chǎn)品可對(duì)精密設(shè)備(例:ATM機(jī),精密機(jī)床等設(shè)備)進(jìn)行24小時(shí)不間斷監(jiān)控,
如果設(shè)備的振動(dòng)頻率超出正常范圍,那么振動(dòng)監(jiān)測(cè)器就可以立刻發(fā)出警報(bào),使用戶將損失降至zui低。從原理上講,振動(dòng)監(jiān)測(cè)器與早期的震動(dòng)傳感器有些類似,都是通過收集一些振動(dòng)波形的能量,再轉(zhuǎn)化為電量進(jìn)行判別。如果傳送的電量超過一定范圍,那么振動(dòng)監(jiān)測(cè)器就會(huì)認(rèn)為是振動(dòng)波形出現(xiàn)了問題,從而自動(dòng)發(fā)出報(bào)警。
但是傳統(tǒng)的震動(dòng)傳感器由于判別不夠精確,因此經(jīng)常發(fā)生一些誤報(bào)或者不報(bào)的現(xiàn)象。
再加上某些行業(yè)市場(chǎng)還不太規(guī)范(特別是ATM監(jiān)控市場(chǎng)),產(chǎn)品魚龍混雜,以次充好,以假亂真,給用戶在選購(gòu)時(shí)帶來一定的困難。為此,這里專門針對(duì)真假震動(dòng)監(jiān)護(hù)器做一些基本的分析。
真正的震動(dòng)監(jiān)護(hù)器能夠?qū)崟r(shí)監(jiān)測(cè)到任何震動(dòng)波形,它能夠以一定的頻率采集不同方向的震動(dòng)數(shù)據(jù),
高性能的震動(dòng)監(jiān)測(cè)器能夠以千分之一秒的速度采集不同三個(gè)方向的震動(dòng)數(shù)據(jù),也即每隔1毫秒采集一次震動(dòng)數(shù)據(jù)進(jìn)行判斷或顯示或記錄。而假的震動(dòng)傳感器一般是通過固定在一根彈簧上的鐵錘的晃動(dòng)來感應(yīng)震動(dòng)信號(hào),當(dāng)震動(dòng)到一定幅度時(shí),鐵錘碰到旁邊的金屬片,形成一次閉路電流,
從而判斷出發(fā)生一次震動(dòng),這種震動(dòng)從原理上來看很容易錯(cuò)過很多破壞性的震動(dòng),并且容易產(chǎn)生誤報(bào),更談不上采集震動(dòng)數(shù)據(jù)了,還有一些假震動(dòng)傳感器將彈簧和鐵錘小型化后封裝到一個(gè)集成電路中,但不管它采取哪種形式都不能采集到震動(dòng)數(shù)據(jù),這是真假震動(dòng)傳感器的zui本質(zhì)區(qū)別
