Expandable Systems: Up to 512 Channels
The Spider-80X is designed for applications in three fields: dynamic data acquisition, vibration control, and machine monitoring. Each front-end features eight analog input channels and two channels that may be software selected as analog outputs for vibration control or tachometer inputs for the analysis of rotating machinery.
A single Spider-80X front-end is a complete two output controller with the same high quality patented dual ADC input technology of the Spider-81 series. The Spider-80X inputs provide single end/differential and AC/DC/IEPE coupling choices; charge mode is an available option that can be installed at the factory. The Spider-80X also provides the same time sync Ethernet connectivity and has 4 GB flash memory for data and program storage. Multiple Spider-80X front-ends may be linked together using the Spider-HUB Ethernet switch from Crystal Instruments. The data storage can be increased to 250 GB by adding a Spider-NAS mass storage device.
The Spider-80X front-ends are onsite swappable. Each front-end is metal-shielded. The user can quickly configure a system with an arbitrary number of front-ends.
The Spider-80SG strain sensing device has the same mechanical form factor as the Spider-80X. These two systems can combine into a system that measures various dynamic signals, including strains or other sensors requiring excitation. Multiple Spider-80X or Spider-80SG front-ends can be hosted in a 64-input chassis.
The Spider-80Xi is a compact version of Spider-80X with an extremely lightweight form factor. Featuring a 64 channel chassis weighing less than 10.5 kg, the Spider-80Xi can be carried in one hand and is optimal for field environment testing where portability is essential.
Like the Spider-80X, multiple chassis combine to create a system up to 512 channels, all sampled simultaneously. A dedicated massive storage hard disk (a 250 GB solid-state drive) allows the time signals of all input channels to record at up to 102.4 kHz/channel. Accurate time synchronization results in excellent phase match in the frequency domain between all channels, either on the same Spider front-end or across different front-ends. Real time FFT, octave, order tracking or vibration control functions can be enabled. The modular boards of the Spider-80Xi are installed at the factory and are not onsite swappable.
The Spider-80Xi system consisting of the 64 channel chassis is powered by AC power, at 100 to 240 VAC. The Spider-80Xi system consisting of the 32 channel chassis is powered by DC power, at 10V to 22V. The latter is also easily operable with an external battery pack. With the Spider-Battery, (developed by Crystal Instruments) a 32 channel Spider-80Xi system operates up to 4 hours without interruption.

EDM software is a complete VCS (Vibration Control System). Crystal Instruments has recently released the new EDM 9.0 release, the most powerful and feature rich version of EDM software. EDM 9.0 release supports the newly introduced hardware units (Spider-80Hi, Spider-80Ci, Spider-20i, Spider-20H, Spider-20HE) that support data acquisition and recording for up to 256 kHz. In addition, the proprietary Multi-Resolution technology has been extended to benefit frequently used Vibration Control tests for Single-axis and MIMO tests. EDM has the following suite of software modules:
