Model 7287 is a very low mass piezoresistive accelerometer weighing less than 1 gram. This accelerometer is designed for crash testing in vehicle crush zone applications, where reuse is not expected. It is very economical to acquire and own, reducing the overall cost of instrumentation. This unit has been designed and assembled using decades of experience that Meggitt has acquired building sensors for the crash industry. As a result, the reliability of the 7287 ensures that critical data is recorded when needed at very low cost.
7287 utilizes a micro-machined sensor which includes integral mechanical stops. This monolithic sensor offers ruggedness, stability and reliability. 7287 has minimum damping, thereby producing no phase shift over the useful frequency range. With a frequency response extending down to dc (steady state acceleration) this accelerometer is ideal for measuring long duration transient shocks. The performance specification is the ideal match for crush zone installations. The ‘-B’ option allows the 7287 to be bolt mounted with use of an integral mounting bracket.
