概述
The Dytran model 7300A1 is a high precision single axis variable capacitance (VC) accelerometer available with a range of 2g with a 4-pin 1/4-28 radial connector. These high performance accelerometers combine an integrated VC accelerometer chip with high drive, low impedance buffer for low level acceleration measurements.
在汽車工業(yè)高速發(fā)展的現(xiàn)代,汽車成為了人們出行主要的交通工具之一,但是因交通事故的傷亡數(shù)量也十分巨大。在信息化的現(xiàn)代利用高科技去挽救人的生命將會是重大研究的主題之一,基于加速度的車禍報警系統(tǒng)正是懷著這種設(shè)計理念,相信這種系統(tǒng)的推廣,會給汽車行業(yè)帶來更多的安全。
Tailored for zero-to-medium frequency applications, the model 7300A1 features a low end frequency response of 0 Hz (DC) and upper frequency range of 400 Hz. This module contains a MEMS capacitive sensing element, a custom integrated circuit amplifier, and differential output, packaged in a rugged aluminum housing weighing 12 grams. Units are easily mounted via two 8-32 screws. On board regulation is provided to minimize the effects of supply voltage variation, and the model 7300A1 is relatively insensitive to temperature changes and thermal gradients.
目前國內(nèi)對導(dǎo)線舞動監(jiān)測多采用視頻圖像采集和運動加速度測量兩種主要技術(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受到影響,在實際使用中只能作為輔助監(jiān)測手段,無法定量分析導(dǎo)線運動參數(shù);而采用加速度傳感器監(jiān)測導(dǎo)線舞動情況,雖可定量分析輸電導(dǎo)線某一點上下振動和左右擺動的情況,但只能測出導(dǎo)線直線運動的振幅和頻率,而對于復(fù)雜的圓周運動,則無法準(zhǔn)確測量。所以我們必須加快加速度傳感器的發(fā)展來適應(yīng)諸如此類環(huán)境下進(jìn)行應(yīng)用。

加速度傳感器主要用于汽車安全氣囊、防抱死系統(tǒng)、牽引控制系統(tǒng)等安全性能方面。
在安全應(yīng)用中,加速度計的快速反應(yīng)非常重要。安全氣囊應(yīng)在什么時候彈出要迅速確定,所以加速度計必須在瞬間做出反應(yīng)。通過采用可迅速達(dá)到穩(wěn)定狀態(tài)而不是振動不止的傳感器設(shè)計可以縮短器件的反應(yīng)時間。其中,壓阻式加速度傳感器由于在汽車工業(yè)中的廣泛應(yīng)用而發(fā)展zui快。
應(yīng)用
1. Airbag testing
2. Crash testing
3. Robotics
4. Seismic monitoring
5. Tilt measurement
加速度傳感器可以檢測上下左右的傾角的變化,因此通過前后傾斜手持設(shè)備來實現(xiàn)對游戲中物體的前后左右的方向控制,就變得很簡單。

磁傳感器是通過測量磁通量的大小來確定方向的。當(dāng)磁傳感器發(fā)生傾斜時,通過磁傳感器的地磁通量將發(fā)生變化,從而使方向指向產(chǎn)生誤差。因此,如果不帶傾斜校正的電子指南針,需要用戶水平放置。而利用加速度傳感器可以測量傾角的這一原理,可以對電子指南針的傾斜進(jìn)行補(bǔ)償。
