4393型是一種帶側(cè)面接頭的壓電式DeltaShear®, Unigain®加速度計(jì)。

4393型有用于輸出的M3接口和用于安裝的M3安裝孔。 使用場(chǎng)景 高頻率 重量輕 振動(dòng)測(cè)試與分析 特點(diǎn) 這種壓電式加速度計(jì)可作為電荷源。其靈敏度用電荷每單位加速度（pC/g）表示。 DeltaShear設(shè)計(jì)涉及三個(gè)壓電元件和三個(gè)振塊，它們排列在三角形中心柱周圍的三角形配置中。該夾緊環(huán)對(duì)壓電元件進(jìn)行預(yù)加應(yīng)力，以保證高線性度。在外殼和夾緊環(huán)之間收集電荷。使用的壓電元件是PZ 23鋯鈦酸鉛元件。外殼的材質(zhì)為鈦。 校準(zhǔn) 在校準(zhǔn)圖中給出的靈敏度是在159.2Hz頻率和10g加速度的情況下測(cè)量的。對(duì)于99.9%置信度，出廠校準(zhǔn)精度為±2%。
