New Ultra-compact Spider-20H, Spider-20HE, & Spider-20i with 256 kHz Sampling Rate
Featuring the highest sampling rate provided in the industry at 256 kHz. Handheld battery powered system with wired & wireless network options and 20V input range. Sync between multiple devices. Choose the convenient portable model or industrial model for permanent mounting.
In June 2020 Crystal Instruments announced the release of EDM 9.0 and the Spider-20H, Spider-20HE, & Spider-20i, the newest editions of the Spider-20 series. These new models are designed for users requiring dynamic signal analyzers and recorders with uncompromising performance and portability.
The Spider-20H, Spider-20HE, and Spider-20i received a hardware upgrade to support an impressive 256 kHz samping rate on all 4 input channels. It is the highest sampling rate offered in the market of compact analyzers. The high sampling rate is especially beneficial for measuring high orders and transient capture in blast tests, pyroshock events, drop shock tests, crash tests, etc.
In addition to the high samping rate, the input range is expanded to 20V to capture larger signals.
The battery power feature along with the wireless network option provides users with maximum portability. Besides a sensor cable, the analyzer can be moved around without an attached power source and computer.
With IEEE 1588 support, the Spider-20H, Spider-20HE, and Spider-20i can synchronize with multiple devices or combine with the Spider-80X to form a large channel system that can be distributed over the same network in a large space, such as an airplane or a large industrial plant.
The Spider-20i features a rugged industrial design, mounting holes, more robust and secure connectors, and a dust-proof, all aluminum chassis to facilitate heat dissipation. Without a battery included, the system is lighter and smaller.
With the combination of the above features, the Spider-20H, Spider-20HE, and Spider-20i are the perfect solutions for many applications including:
Machinery Diagnosis
Machine/Process Monitoring
Modal Analysis
Vehicle Dynamics
Production Testing
Temporary Monitor
Acoustic Studies
Transient Capture
Components included in rockets and space vehicles are subject to severe shock vibrations. To ensure reliability during missions, testing is undertaken using controlled explosives. A high sampling rate data acquisition device to acquire data from the shock sensors can reliably measure the high frequency content during these tests.
Shock Response Spectrum (SRS) calculations need sampling rates that are at least 10 times the maximum frequency of interest. With a limitation of 102.4 kHz, frequencies of up to only 10 kHz can be analyzed. With the new generation of Spiders, the SRS spectrum for maximum frequencies of 25 kHz can be acquired and analyzed.
In addition, by capturing the data at the maximum possible sampling rate, all the time domain features are effectively captured and preserved. Users can process the acquired data in real time or post process with different settings to completely analyze the data.
