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