　　Industries: Engine and Vehicle, General Industry

　　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.

　　产品描述:

　　3022是一款硅压阻加速度传感器，陶瓷上盖和基板封装。当用户进行特殊粘结时陶瓷基板提供非常好的粘合表面。3022的感应元件包括一个硅质量块，硅边框，和将质量块悬挂于边框的多个悬梁。质量块的运动使悬梁产生应力，悬梁上压电电阻的阻值则随着应力的变化而改变。元件上面和下面的硅帽作为机械限位为传感器提供过载保护。传感器具有体积小、抗冲击、耐用、内置阻尼等特点。带安装支架的同类加速度传感器，请参照3028；带温度补偿的型号，请参照3052和3058。

　　特点:

　　压阻式MEMS技术
