　　Description: The Model 3022 is a piezoresistive silicon accelerometer packaged in a ceramic substrate with a sealed ceramic cover. The ceramic provides an excellent bonding surface for the customers application specific adhesive. 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 overrange 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 a mounting bracket designed to bolt the sensor to a mounting location, see the Model 3028. Please refer to the Models 3052 and 3058 for accelerometers with integral temperature compensation.

　　產(chǎn)品描述:

　　3022是一款硅壓阻加速度傳感器，陶瓷上蓋和基板封裝。當用戶進行特殊粘結時陶瓷基板提供非常好的粘合表面。3022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(chǎn)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(nèi)置阻尼等特點。帶安裝支架的同類加速度傳感器，請參照3028；帶溫度補償?shù)男吞�，請參�?052和3058。
