Manufacturing plants often require controlled vibrations on various parts of the plant to run for several hours, days, or even weeks at a time. In some cases, continuous operation is required.
At these facilities, the affordable down time is limited to a few hours in a week. The continuous controlling and monitoring of independently running systems is another significant challenge. Read More
Applying strain gages for measurement may sound daring, but it’s a lot simpler than it sounds. In this article, we will focus on key points of strain gage placement technique. It is important that the strain gage performs well and gives an accurate reading. This means the attachment point must be performed correctly to receive good results. As a result, the strain gage setup process requires a precise and correct following of directions. Crystal Instruments’ Spider-80SG is capable of calibrating and resetting measurement values prior to taking measurement. This is a standard step for all strain measurements to eliminate any offset before measurement starts. Read More
There are often instances where it may be beneficial to add location information to your acquired data. With the CoCo-80X, these GPS signals can be acquired simultaneously with other measurements -- there is no need to carry a separate GPS device. The CoCo-80X’s large LCD and touch-screen interface makes it easy to use the analyzer and acquire data. All measurements are combined into a single test file, so there’s no need to manage files.

I’ve always wondered why some instruments in the market set their hardware input range to 10 V. Perhaps the hardware designer for these instruments possessed ten fingers and chose 10 V out of convenience. I can imagine their bosses eagerly approving the use of 10 V as well, because they too have ten fingers! Read More
EDM Modal is a complete Modal Testing and Modal Analysis suite for Experimental Modal Analysis (EMA). It works on the verified Spider hardware systems, ranging from several channels up to hundreds of channels. EDM Modal is developed based upon the sophisticated technologies of modern modal analysis theory and technique. With its intuitive controls and powerful features, EDM Modal is the ultimate tool for modal analysis applications. Read More

Dynamic data acquisition and machine monitoring in factories and plants often require data to be acquired synchronously at various parts of the plant or a factory. Some big machines, especially in the aerospace industry also require data to be acquired at different areas synchronously.

Strain gages setup on our Spider-80SG is one of the most common questions we received. The Spider-80SG is designed to be used with strain gages; wonderfully, software interface is still within the same easy-to-use and intuitive platform of our EDM software. The connection to Spider-80SG breakout box is the final piece of the puzzle and it is a lot simpler than it looks.
What does an automotive engineer, electric engineer, and an airline acoustics engineer have in common? They all had the amazing idea to attend the Crystal-Instruments-sponsored 2017 SAE Noise and Vibration Conference and Exhibition in Grand Rapids, Michigan in June 2017. Read More
I recently received a returned CoCo-80 unit from a customer located in India. This customer decided to upgrade their unit to the newer CoCo-80X model. The returned CoCo-80 unit was manufactured and shipped in 2007. This particular unit that was returned to us was the 26th CoCo-80 unit that Crystal Instruments produced. Read More
Shock Response Spectrum (SRS) Analysis is one of the most often-used methods in Shock and pyro-shock analysis. Recently, Virgin Orbit, a newly formed company under Virgin Groups that target at advanced small satellite business, started to use Crystal Instruments’ Spider-80X to acquire the shock vibration and SRS analysis.
