比较SDI通用模块
所有的SDI的高性能，低噪音万向加速度模块是基于相同的气密密封，氮阻尼，电容提供两个DC（恒定）和AC（振动）响应传感器。SDI的定制的ASIC允许它产生各种加速度产品输出，灵敏度，和形式因子，以适应几乎任何应用程序，DC或AC。
下面列出的车型是他们的单人或家庭三轴和G-范围内几乎可以互换的。用户可以指望一2210-025和2260-025或2460-002和2466-002之间的一致的性能。他们都共享SDI模块闻名同一易于使用的特质：
+8至+ 32V励磁
既提供±4 V DC差分输出和4.5V单端输出
集成放大和缓冲输出
Compare SDI Universal Modules
All of SDI’s high performance, low noise universal accelerometer modules are based upon the same hermetically sealed, nitrogen damped, capacitive sensor which provides both DC (constant) and AC (vibration) response. SDI’s custom ASICs allow it to produce a variety of accelerometer products with outputs, sensitivities, and form factors to fit nearly any application, DC or AC.
The models listed below are virtually interchangeable within their single or triaxial families and g-ranges. Users can count on consistent performance between a 2210-025 and 2260-025, or between a 2460-002 and 2466-002. They all share the same ease-of-use qualities that SDI modules are known for:
+8 to +32V Excitation
Supplying both ± 4 V DC Differential Output and 4.5V Single Ended Output
Integrated amplification and buffered outputs

Frequency response is shown as MINIMUM to ensure they work in your application. Most accelerometers exceed this minimum greatly.
All of these SDI accelerometer modules will...
Easily withstａnd intentional and unintentional 2000+ g drop shocks
Detect AC, DC (0 Hz), pulsating, and variable frequencies
Cost less because Silicon Designs is the accelerometer OEM
Obsolete external charge amps by using a low impedance output
Support self-calibration for quick deployment
