深度技術(shù)內(nèi)容
1、 工業(yè)設(shè)備振動(dòng)的典型故障類型
l 軸承磨損、軸不對(duì)中、齒輪斷齒的頻譜特征(附FFT頻域分析圖)
l 風(fēng)力發(fā)電機(jī)與數(shù)控機(jī)床的振動(dòng)監(jiān)測(cè)標(biāo)準(zhǔn)差異(引用ISO 10816-3與ISO 7919)
2、PCB 356A32加速度計(jì)的技術(shù)突破

場(chǎng)景 | PCB 356A32信噪比 | 競(jìng)品X信噪比 |
燃汽輪機(jī)(200℃) | 78dB | 65dB |
礦山破碎機(jī)(高粉塵) | 穩(wěn)定輸出 | 數(shù)據(jù)跳變 |
3、 抗干擾設(shè)計(jì)實(shí)踐
l IEPE恒流供電技術(shù)消除長(zhǎng)電纜噪聲(對(duì)比傳統(tǒng)電荷放大器方案)
