Page 2: ... addition to being undamped the 727 series has no mechanical stops maximizing both bandwidth and amplitude linearity Its undamped characteristic allows it to be used in applications where the peak acceleration is known and there is not a significant amount of out of band energy that could cause enough resonance excitation to exceed the overrange limit of the accelerometer Due to the severe environ...

Page 4: ...HANDLING The 727 series of drop test accelerometers are supplied with integral cables which are terminated in pigtails The user can select an appropriate end connector There are two important considerations regarding the integral cable when installing the accelerometer First since the cable will be exposed to the same high level shocks as the accelerometer care needs to be taken to prevent damage ...
