Model 288D01 Mechanical Impedance Sensor simultaneously measures an applied, driving-point force and response acceleration of a test structure for determining parameters such as mechanical mobility and mechanical impedance. The unit consists of a precision, shear mode accelerometer and a quartz force sensor in a common housing. Installation is primarily facilitated at the structural excitation points, in series with a stinger and vibration shaker.
Model 356B41 triaxial seat pad accelerometer measures whole body vibration influences associated with vehicle operation. The unit houses a triaxial accelerometer within a molded, rubber pad that can be placed under a seated person, beneath a weighted test object, or strapped onto the body.
