ICP® Mechanical Impedance Sensor
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. |
Highlights
- 100 mV/g [10.2 mV/(m/s2)] acceleration sensitivity
- 100 mV/lb [22.4 mV/N] force sensitivity
- 0.7 to 7000 Hz frequency range
19.2 gram weight

Portable 1g Handheld 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.
*Total weight including mounting hardware and cable influence |

Back-to-back Comparison Calibration Standards
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. |
Highlights
- 100 mV/g sensitivity
- 0.5 Hz to 10 kHz (± 5%) frequency range
- 85 to 264 VAC, 47 to 440 Hz powered
- Optional battery powered
