With the Mini-Shaker, we wanted to get rid of the bulky standalone power amplifiers many shakers require. The result is a compact, highly-portable shaker ideal for education and research.

The Mini-Shaker provides a stable frequency range from 0.3 Hz - 15,000 Hz: more capability for testing. Not to mention, its Bare Load can take up to 20,000 Hz.

Our sturdy trunnion design allows the Mini-Shaker to be rotated and locked in any angle from vertical to horizontal orientations. And by sturdy, we mean sturdy.
The Spider-81 series is a highly modular, distributed, scalable vibration control system developed by Crystal Instruments. It represents the newest generation of vibration control systems with advanced technology unseen in the current generation.
The Spider-81B vibration test controller is developed to meet the requirements of basic vibration testing applications. It has 4 inputs, 1 output, and 4 pairs of digital I/O.
Through enhanced control algorithms and a simplified DSP architecture, the Spider-81B greatly reduces the feedback loop time of Sine and Random control—perfect for structures with high Q resonances, and resonance search and dwell.
Using a patented dual parallel A/D design, the Spider-81B achieves 150 dBFS input dynamic range. Each measurement channel can detect signals as small as 6 μV and as large as 20 V. This design completely eliminates the need for the input range or gain settings found on traditional controllers.

Random Vibration Control provides precise multi-channel control in real time. The device under test is subjected to true random noise with a precisely shaped spectrum with either Gaussian or non-Gaussian amplitude statistics. With a control dynamic range up to 90 dB, up to 512 channels can be enabled for Control, Notching, Monitoring and time data recording. The recording option records time-stream data at the full sample rate on all input channels. A unique hardware/firmware/software design featuring spectral overlapping provides a fast loop time of less than 15 ms in a typical test.
Swept Sine Vibration Control provides precise multi-channel control in real time. It provides a spectrally pure undistorted sine wave and a control dynamic range of up to 100 dB. As many as 256 channels can be enabled for Control, Notching, Monitoring and time-data recording. The recording option records a time-stream at the full sample rate on all input channels. A unique hardware design and spectral overlapping provides a fast loop time of less than 10 ms.
