Vibration Controllers





The Spider-81 is a 4th generation vibration control system developed by Crystal Instruments. It is the first controller that directly integrates the time-synchronized Ethernet connectivity with embedded DSP technology, greatly increasing the control performance, system reliability, and failure protection.

Dual, parallel 24-bit A/Ds provide 130 dB of dynamic range for even low level tests and a modular design allows expansion up to 64 input channels. Tests can be executed in Black Box mode, which allows it to operate without a PC. A complete suite of vibration tests are available including, Sine, Random, SoR, RoR, RSTD, TTH, TDR, Shock and more. Also available is a full suite of general signal analysis functions.


The Spider-80X is a scalable vibration control and measurement system that supports 8 to 512 input channels. Each module has voltage and IEPE inputs which are ideal for shock, vibration and acoustic measurement. All time data can be recorded at full speed during vibration control.
