概述
The Dytran 7500A1 is a high precision single axis variable capacitance (VC) accelerometer available with a range of 2g. This high performance accelerometer combines an integrated VC accelerometer chip with high drive, low impedance buffer for low level acceleration measurements.
压电式加速度传感器又称压电加速度计。它也属于惯性式传感器。压电式加速度传感器的原理是利用压电陶瓷或石英晶体的压电效应,在加速度计受振时,质量块加在压电元件上的力也随之变化。当被测振动频率远低于加速度计的固有频率时,则力的变化与被测加速度成正比。
Tailored for zero-to-medium frequency applications, the model 7500A1 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, low noise electronics and differential output, housed in a lightweight titanium, with a 4-pinradial connector and easy mounting via two #4 or M3 screws. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
基于世界领先的MEMS硅微加工技术,压阻式加速度传感器具有体积小、低功耗等特点,易于集成在各种模拟和数字电路中,广泛应用于汽车碰撞实验、测试仪器、设备振动监测等领域。
通过测量由于重力引起的加速度,你可以计算出设备相对于水平面的倾斜角度。通过分析动态加速度,你可以分析出设备移动的方式。但是刚开始的时候,你会发现光测量倾角和加速度好像不是很有用。但是,工程师们已经想出了很多方法获得更多的有用的信息。
