Available with a 5g range, the Dytran model 7602B1 incorporates a MEMS capacitive sensing element and an advanced ASIC to simulate piezoresistive bridge operation, as well as an integrated VC accelerometer chip with high drive, low impedance buffering. Units respond to both DC and AC acceleration. On-board regulation minimizes supply voltage variation effects, making them relatively insensitive to temperature changes and thermal gradients. Sensors are hermetically sealed for reliable operation in high humidity and dirty environments, a feature a custom integrated circuit amplifier and differential output stages, with a 4-pin M4.5 x 0.35 radial connector, and easy mounting via two 4-40 screws.

目前國(guó)內(nèi)對(duì)導(dǎo)線(xiàn)舞動(dòng)監(jiān)測(cè)多采用視頻圖像采集和運(yùn)動(dòng)加速度測(cè)量?jī)煞N主要技術(shù)方案。前者在野外高溫、高濕、嚴(yán)寒、濃霧、沙塵等天氣條件下，不僅對(duì)視頻設(shè)備的可靠性、穩(wěn)定性要求很高，而且拍攝的視頻圖像的效果也會(huì)受到影響，在實(shí)際使用中只能作為輔助監(jiān)測(cè)手段，無(wú)法定量分析導(dǎo)線(xiàn)運(yùn)動(dòng)參數(shù)；而采用加速度傳感器監(jiān)測(cè)導(dǎo)線(xiàn)舞動(dòng)情況，雖可定量分析輸電導(dǎo)線(xiàn)某一點(diǎn)上下振動(dòng)和左右擺動(dòng)的情況，但只能測(cè)出導(dǎo)線(xiàn)直線(xiàn)運(yùn)動(dòng)的振幅和頻率，而對(duì)于復(fù)雜的圓周運(yùn)動(dòng)，則無(wú)法準(zhǔn)確測(cè)量。所以我們必須加快加速度傳感器的發(fā)展來(lái)適應(yīng)諸如此類(lèi)環(huán)境下進(jìn)行應(yīng)用。
