CALIBRATION IMPACT HAMMER |
摘要 |
An instrumented hammer that gives the operator a measurement of the impact energy of each hammer blow. A head or main body portion slidably receives an inertia rod spring mounted in a longitudinal bore therein. Upon striking a surface, momentum causes movement of the rod forward against the spring pressure. A slot on the rod movesthrough an optical switch which emits a signal relative to the movement of the slot therethrough. A display assembly receives the signal and calculates the impact energy of the hammer blow. |
