概述
The Dytran 7701A1 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.
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。
Available with a 5g range, the Dytran model 7701A1 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 DC 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 5-pin M5-5 radial connector and 10-32 stud mounting capabilities.
地震检波器是用于地质勘探和工程测量的专用传感器，是一种将地面振动转变为电信号的传感器，能把地震波引起的地面震动转换成电信号，经过模/数转换器转换成二进制数据、进行数据组织、存储、运算处理。加速度传感器是一种能够测量加速力的电子设备，典型应用在手机、笔记本电脑、步程计和运动检测等。
The Dytran model 7701A1 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.
在汽车工业高速发展的现代，汽车成为了人们出行主要的交通工具之一，但是因交通事故的伤亡数量也十分巨大。在信息化的现代利用高科技去挽救人的生命将会是重大研究的主题之一，基于加速度的车祸报警系统正是怀着这种设计理念，相信这种系统的推广，会给汽车行业带来更多的安全。
