Abstract
A vibration sensor includes a housing, a high G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; a low G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; and a processor installed within the housing to receive data from the high G accelerometer and the low G accelerometer. A method for using the vibration sensor includes employing the low G and the high G acceleration data. Another vibration sensor includes intrinsically safe buttons.
