    加速度传感器是一种能够测量加速力的电子设备。加速力就是当物体在加速过程中作用在物体上的力，就好比地球引力，也就是重力。加速力可以是个常量，比如g，也可以是变量。加速度计有两种：一种是角加速度计，是由陀螺仪（角速度传感器）的改进的。另一种就是线加速度计。

    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。

History

The company was founded by Richard Weber in 1944 under the nameUnis in Radebeul near Dresden. It was named Metra in 1954.

In the late fifties Metra began to manufacture the firstpiezoelectricsensors. This pioneering technology was introduced at Metra by Prof.Lenk and Dr. Erler. Reason for this development was the increasingdemand for vibration sensors by the emerging aircraft industry.

During the sixties and seventies Metra developed a broad rangeof vibration sensors and instruments.

Metra developed and produced own piezoceramic materials.
