The Spider-20 series of products are compact yet powerful data acquisition and dynamic measurement systems. These units provide four 24-bit precise high-fidelity input channels, and a unique software-selectable tachometer-input/signal-source output channel. Each input is individually programmable to accept AC or DC voltage or output from an IEPE (ICP) sensor with built-in electronics. Input channels can be programmed to sample up to a rate of 256 kHz. The Spider-20HE is a small scale (5 ⁵/16 x 4 ⁵/16 x 1 ⁵/16 inch) device weighing only 18 ounces. This handheld unit features three push-button controls and five LED status indicators. This little powerhouse can run over 6 hours on its internal rechargeable battery which can be replaced in the field with a backup battery.

The compact battery-less version with industrial grade enclosure makes the Spider-20i suitable for deployment in rugged industrial environments. Without any buttons, it is suitable to be deployed in remote locations enabling operation and monitoring entirely through software applications.

The Spider-20 series of products communicates with the world through an Ethernet interface. Link the Spider to your laptop or tablet running Windows and enjoy the full suite of functionality provided by our EDM (Engineering Data Management) software, including spectral analysis and frequency response functions, 1/nth octave acoustic functions, order tracking for rotating machinery, shock response spectra for drop testing, or digital filtering for special purpose analysis.

The Spider-20HE can chain systems together to construct a high channel count system with up to 256 input channels while simultaneously sampling all input data. Crystal Instruments’ unique PTP (Precision Time Protocol) technology ensures better than 1° phase match for up to 20 kHz.

The Spider-20 series of products are equipped with built-in 4 GB of flash memory. Raw time signals can be recorded with sampling rates of up to 256 kHz with a push of a button or through an automated schedule. It is also capable of periodically saving processed time and frequency signals. A unique Black Box mode enables Spiders to run without requiring a connection to a host PC.
