新品液晶顯示**磨音測量儀電耳作原理

新品液晶顯示**磨音測量儀/磨音測量儀/**磨音檢測儀/電耳 作原理

、作原理:

**磨音測量儀通過安裝在現(xiàn)場的*結(jié)構(gòu)的探頭，接收磨機發(fā)出的噪聲，經(jīng)屏蔽電線傳輸?shù)絻x器。轉(zhuǎn)換為數(shù)字百分比顯示，同時輸出與顯示值成比例的4~20mA電流信號供后端DCS 系統(tǒng)采集使用。顯示物料位值與磨內(nèi)物料填充量成正比，反比于磨機發(fā)出的噪聲，因此它能定量的測盤磨機負荷的大小。操作人員可以根據(jù)磨音的低控制各種入磨原料的流量，從而實現(xiàn)對磨機負荷的控制，使磨機產(chǎn)量提，電耗*低。其內(nèi)具有矯正信號源，以便維護人員檢查維護，并具有飽磨空磨聲光報警裝置，可以提醒操作人員及時作出處理。

二、性能標:
1、測量范圍:000%~
2、探頭阻抗:600Q±15%
3、頻響:50~18，000HZ
4、頻率范圍20~16000Hz
5、靈敏度:-34~-49dB(0dB=1V/Pa，1KHz)
6、信噪比≥58dB
7、模擬輸出兩路標準4~20mA
8、數(shù)字輸出 RS-485故障安
9、測量誤差:±0.1%
10、恒流精度: 負載變化時，輸出電流變化優(yōu)于0.5%11、防護等:IP65
12、作溫度:-20℃~60℃13、環(huán)境濕度:<85%
14、電源電壓:輸入:50Hz，~220V±15%15、機箱尺寸:x寬x深73x150x160mm16、帶負載能力:<2K
三、本款測量儀與市場上產(chǎn)品相比有如下優(yōu)勢:
1、液晶顯示，中文菜單顯示，容易操作
2、產(chǎn)品質(zhì)量輕巧，安裝方便
3、抗電流，電壓沖擊能力強。
4、頻率范圍寬，響應特性好;
5、有源濾波，具有選頻特性;
6、磨音信號穩(wěn)定平滑;
7、向性好，受鄰機干擾小;
8、本身有自校準信號，可以行機內(nèi)校準:
9、磨音傳感器為密封型，可適用于濕度、粉塵條件:
10、與控制計算機聯(lián)接構(gòu)成磨機負荷控制系統(tǒng)能提磨機產(chǎn)量，防止飽磨空磨減輕人勞動強度，提勞動生產(chǎn)率。
