Seismic Vibration Testing

Validate Low Frequency Vibration Sensors and Systems

Slow speed or low frequency vibration measurement applications demand special transducer types. The sensors commonly found in these applications are high-output piezoelectric accelerometers, capacitive accelerometers made from MEMS technology, or velocity transducers with either a piezoelectric or moving coil sensing element. Applications such as hydropower, aviation, and automotive demand the low frequency performance and resolution of these technologies. Low Frequency Portable Vibration Calibrators and Shaker Tables from The Modal Shop are ideal for confirming the accuracy of this instrumentation in the field before a critical test or in the lab.
