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 394C06 handheld shaker is a small, self-contained, battery powered, vibration exciter specifically designed to conveniently verify accelerometer and vibration system performance. It accepts sensors up to 210 grams* in weight and delivers a controlled, 1 G mechanical excitation. Ideal for conducting on-the-spot sensor sensitivity checks, identifing channels for multi-point data acquisition, performing end-to-end system troubleshooting, and confirming system gain settings.

Back-to-back comparison calibration standard accelerometers permit NIST traceable calibration of accelerometers and other vibration sensors by the reference comparison method. The back-to-back reference calibration accelerometer is mounted to a mechanical exciter and the sensor to be calibrated is installed onto its surface. The output signals from the reference standard and transducer under test (TUT) are compared, permitting sensitivity, frequency response, and phase response verification of the tested unit. Frequency and amplitude inputs to the exciter can be varied to suit the desired test parameters. Included are interconnect cables and a dedicated signal conditioner for use with the reference standard to ensure a precise sensitivity at a common reference frequency. A variety of mounting studs and an NIST traceable calibration certificate are also provided. Readout instruments, shakers, and their controllers are not included.
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.
Model HVM-100 Human Vibration Meter utilizes accelerometer inputs to provide vibration severity measurements relative to human exposure to vibration. The unit is directly compatible with Model 356B41, triaxial seat pad accelerometer, as well as any other single axis or triaxial ICP® accelerometer.
