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.

(Choose Random or Sine Software)
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.
