　　Industries: Engine and Vehicle, General Industry

　　Description: The Model 3028 is a piezoresistive silicon accelerometer packaged on a ceramic substrate with a metal bracket which can be used to bolt the sensor to the mounting location. The accelerometer consists of a micro machined silicon mass suspended by multiple beams from a silicon frame. Piezoresistors located in the beams change their resistance as the motion of the suspended mass changes the strain in the beams. Silicon caps on the top and bottom of the device are added to provide over-range stops. This design provides for a very low profile, high shock resistance, durability and built-in damping over a wide usable bandwidth. For an accelerometer with an adhesive mount design, see the Model 3022. Please refer to the Models 3052 and 3058 for accelerometers with integral temperature compensation.

　　產品描述:

　　3028是一款硅壓阻加速度傳感器，陶瓷上蓋和基板封裝，并帶有金屬支架，方便螺絲安裝。3028的感應元件包括一個硅質量塊，硅邊框，和將質量塊懸掛于邊框的多個懸梁。質量塊的運動使懸梁產生應力，懸梁上壓電電阻的阻值則隨著應力的變化而改變。元件上面和下面的硅帽作為機械限位為傳感器提供過載保護。傳感器具有體積小、抗沖擊、耐用、內置阻尼等特點。粘貼安裝的同類加速度傳感器，請參照3022；帶溫度補償的型號，請參照3052和3058。

　　特點:

　　壓阻式MEMS技術
　　靜態響應
　　mV輸出
　　低成本
　　螺絲釘安裝
　　±0.5%非線性（典型值）
　　氣態阻尼
　　內置過載限位
　　低功耗
