Front-End Hardware
Overview
Crystal Instruments currently have several products that are network based –
Spider-20, Spider-80X, Spider-80SG, and Spider 81/81B. Each product is
designed by state-of-art technology to meet various needs. The Spider-80SG
hardware is not included in this chapter but is described in detail in Strain
Measurement and Analysis chapter.
Spider-20
Spider-20 is a compact yet powerful digital data recorder and dynamic signal
analyzer. It provides four 24-bit precise high-fidelity input channels, and a unique
software-selectable tachometer-input/signal-source output channel (all using
conventional BNC connectors). Each input is individually programmable to
accept AC or DC voltage or output from an IEPE (ICP) sensor with built-in
electronics.
Spider-20 is a diminutive 5.3” x 4.3” x 1” tool weighing only 18 ounces. It has only
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
field with a backup battery. It can also record data on its built-in 4GB flash
memory at the simple push of a button.
Spider-20 communicates with the world through its built-in Wi-Fi interface. Use
your iPad to setup and view or record time histories as well as perform spectrum
analysis or measure Frequency Response and Coherence functions. Link the
Spider-20 to your laptop or tablet running Windows and enjoy the full repertoire
of functionality provided by our EDM (Engineering Data Management) software
including 1/nth Octave acoustic functions, Order Tracking for rotating machinery,
Shock Response Spectra for drop testing, or Digital Filtering for special purpose
analysis.
Transfer measured data to truly massive storage space using the EDM Cloud
server. EDM can be used to program your Spider-20 to perform a custom
measurement or measurement sequence at the touch of its START button,
making it an unintimidating and user-friendly tool. No computer, tablet or
phone is required; just use your thumb and Spider-20 operating in Black Box
mode. Use our flexible Automated Schedule and Limiting software to turn this
Spider into an intelligent unattended monitor capable of responding to data
conditions or networked instructions, notifying you of significant conditions
via e-mail.
Spider-80X
The Spider-80X is a highly modular, truly distributed, scalable dynamic
measurement system introduced by Crystal Instruments. The Spider-80X is ideal
for a wide range of industries including automotive, aviation, aerospace,
