V315A系列低頻壓電式加速度傳感器,振動(dòng)傳感器
V315A系列產(chǎn)品是一款振動(dòng)測(cè)量用 IEPE 加速度傳感器,特點(diǎn)是采用環(huán)形剪切模式的陶瓷晶體為敏感元件,具有長(zhǎng)期保持輸出穩(wěn)定的特性。此加速度傳感器的內(nèi)部電路是在 IEPE 系統(tǒng)的兩線制上同時(shí)提供恒流源激勵(lì)和傳輸?shù)妥杩闺妷狠敵鲂?/span>號(hào),信號(hào)地內(nèi)部屏蔽,并與外殼隔離;同時(shí)信號(hào)放大電路設(shè)計(jì)考慮了極性反向保護(hù)。外殼采用激光焊接工藝以保證產(chǎn)品的密封性;輸出連接頭采用標(biāo)準(zhǔn)的 MIL-C-5015 玻璃絕緣連接器以滿足不同環(huán)境下使用時(shí)輸出的穩(wěn)定性;315A 系列加速度傳感器支持粘合劑安裝,也支持 1/4-28 的螺紋孔牢固安裝。315A 系列加速度傳感器具有頻帶響應(yīng)寬和抗沖擊的特性,所以常在有意外沖擊信號(hào)的環(huán)境下用于工業(yè)振動(dòng)監(jiān)控。
