概述
The Dytran 3010M14 is a primary transfer standard accelerometer, and is designed to transfer standard vibration calibration data from standards organization such as NIST, to back-to-back calibration accelerometers such as Dytran models 3120B and 3123A, which are then used to calibrate other accelerometers.
压电式加速度传感器是基于压电晶体的压电效应工作的。某些晶体在一定方向上受力变形时,其内部会产生极化现象,同时在它的两个表面上产生符号相反的电荷;当外力去除后,又重新恢复到不带电状态,这种现象称为“压电效应”,具有“压电效应”的晶体称为压电晶体。常用的压电晶体有石英、压电陶瓷等。
Back-to-back (reference) accelerometers offer a convenient means of determining the sensitivty and frequency response characteristics of unknown acceleration, velocity and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the model 3010M14 to accomplish in-house NIST traceable calibrations, Model 3010M14 is available with a 10 mV/g sensitivity, 10-32 tapped hole for mounting, and 10-32 axial connector.
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。

1. 10 mV/g
2. 500g range
3. 1 to 5,000 Hz frequency range (±5%)
4. 10-32 axial connector
5. 10-32 tapped hole
6. 21 grams
7. Stainless steel
8. Hermetic
9. Calibration reference accelerometer
10. IEPE
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。
应用
1. Back-to-back accelerometer calibration
2. Low frequency, low g level measurements
3. NIST traceable calibrations (when used with appropriate electrodynamic shaker, power supply and control system)
