Meggitt Sensing Systems - 美捷特 7280AM4 冲击传感器

The Endevco model 7280AM4 is a family of rugged lightly damped piezoresistive accelerometers designed for high amplitude acceleration, vibration and shock applications. The model 7280AM4 features minimal mass loading, broad frequency response, and minimum zero shift during a shock event.","The model 7280AM4 uses a unique micro-machined, piezoresistive sensor with light gas damping to attenuate resonant amplitudes, and mechanical stops to reduce breakage under overload conditions. The monolithic sensor incorporates the latest MEMS technology for ruggedness, stability and reliability to 4X full scale range. The accelerometer features a four-active arm bridge circuit. The M4 modification provides in integral 1⁄4-28 mounting stud in a light 2.1 gram package. This increases the housing stiffness, which is important for short duration shock measurements.
