比較SDI通用模塊
所有的SDI的高性能提供堅實支撐，低噪音萬(wàn)向加速度模塊是基于相同的氣密密封，氮阻尼高產，電容提供兩個(gè)DC（恒定）和AC（振動(dòng)）響應(yīng)傳感器。SDI的定制的ASIC允許它產(chǎn)生各種加速度產(chǎn)品輸出發揮作用，靈敏度良好，和形式因子，以適應(yīng)幾乎任何應(yīng)用程序發揮，DC或AC顯著。
下面列出的車(chē)型是他們的單人或家庭三軸和G-范圍內(nèi)幾乎可以互換的。用戶(hù)可以指望一2210-025和2260-025或2460-002和2466-002之間的一致的性能開放以來。他們都共享SDI模塊聞名同一易于使用的特質(zhì)：
+8至+ 32V勵(lì)磁
既提供±4 V DC差分輸出和4.5V單端輸出
集成放大和緩沖輸出
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:

Frequency response is n 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
