INSTRUMENTATION

The instrument in general use on railroads for measuring longitudinal shocks is the single plane impact register. This device consists of a weight resistricted from movement in all planes except longitudinal, where it is restrained by a spring. A stylus is attached to the weight and marks the weights movement on a paper chart fed continuously by a clock mechanism. For accurate measurement of impact shocks or vibrations, accelerometers must be used. Accelerometers should be linear within a range of plus or minus 25 G's, and capable of withstanding occasional shocks to 50 G's. Accelerometers measure the apparent weight of the body to which they are attached, 1 G is a force equal to the weight of the body.
