概述

The Dytran 7600B1 is a high precision variable capacitance (VC) accelerometer, designed to be used as a drop-in replacement for piezoresistive units in new or existing zero-to-medium frequency instrumentation applications.

壓電式加速度傳感器又稱壓電加速度計(jì)骄闺。它也屬于慣性式傳感器捎谨。壓電式加速度傳感器的原理是利用壓電陶瓷或石英晶體的壓電效應(yīng)涛救，在加速度計(jì)受振時(shí)程储，質(zhì)量塊加在壓電元件上的力也隨之變化臂寝。當(dāng)被測(cè)振動(dòng)頻率遠(yuǎn)低于加速度計(jì)的固有頻率時(shí)败徊，則力的變化與被測(cè)加速度成正比俊揣。

Available with a 5g range, the Dytran model 7600B1 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, and 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.

電容式加速度傳感器是基于電容原理的極距變化型的電容傳感器膀琐。電容式加速度傳感器/電容式加速度計(jì)是對(duì)比較通用的加速度傳感器莉孽。在某些領(lǐng)域*，如安全氣囊苦旋，手機(jī)移動(dòng)設(shè)備等火晕。電容式加速度傳感器/電容式加速度計(jì)采用了微機(jī)電系統(tǒng)（MEMS）工藝璃弄，在大量生產(chǎn)時(shí)變得經(jīng)濟(jì)脐供，從而保證了較低的成本托猩。

The Dytran model 7600B1 accelerometer uses the same power supply as piezoresistive and strain gage sensors, allowing them to operate as stand-alone differential output accelerometers or in place of piezoresistive bridge-type accelerometers.

伺服式加速度傳感器是一種閉環(huán)測(cè)試系統(tǒng)枕络，具有動(dòng)態(tài)性 能好孙已、動(dòng)態(tài)范圍大和線性度好等特點(diǎn)涝桅。其工作原理，傳感器的振動(dòng)系統(tǒng)由 "m-k”系統(tǒng)組成盐肃，與一般加速度計(jì)相同没靖，但質(zhì)量m上還接著一個(gè)電磁線圈锚倦，當(dāng)基座上有 加速度輸入時(shí)，質(zhì)量塊偏離平衡位置，該位移大小由位移傳感器檢測(cè)出來(lái)，經(jīng)伺服放大器 放大后轉(zhuǎn)換為電流輸出自阱，該電流流過(guò)電磁線圈，在*磁鐵的磁場(chǎng)中產(chǎn)生電磁恢復(fù)力询烤，力圖使質(zhì)量塊保持在儀表殼體中原來(lái)的平衡位置上吟税，所以伺服加速度傳感器在閉環(huán)狀態(tài)下工作。由于有反饋?zhàn)饔?/span>提佣，增強(qiáng)了抗的能力吮蛹，提高測(cè)量精度，擴(kuò)大了測(cè)量范圍拌屏，伺服加速度 測(cè)量技術(shù)廣泛地應(yīng)用于慣性導(dǎo)航和慣性制導(dǎo)系統(tǒng)中潮针，在高精度的振動(dòng)測(cè)量和標(biāo)定中也有應(yīng)用。
