Sentek Dynamics is pleased to announce its extensive product offering of high quality, lab grade permanent magnet shakers for “desktop” and “modal” vibration testing applications. Sentek Dynamics’ permanent magnet shakers are based on years of vibration testing experience and offer a proven solution to demanding vibration testing requirements.
Sentek Dynamics is the leader in the field of single and multi-axis electrodynamic shakers. Sentek Dynamics’ product line includes air and water-cooled single axis and simultaneous three-axis shakers in a broad choice of forces. The simultaneous three-axis shakers bring real-world vibration environments to test laboratories.
Sentek Dynamics’ Mini “Combo” Shaker & Controller Kit The Sentek Dynamics’ Mini “Combo” Shaker is a small, portable 20 N (4.5 lbf) permanent magnet shaker with an integral power amplifier. The design eliminates the need for a separate, inconvenient power amplifier and attendant cables. The drive signal from most vibration controllers and signal generators can be directly connected to the BNC connector on the body of the shaker.
Sentek Dynamics’ mini “combo” shaker can be ordered with an optional slip table. The trunnion design allows the mini-shaker to be rotated and locked for testing in any of three axes.
Small satellites, more commonly known as CubeSats, have gained popularity because of their miniature size and their data acquisition techniques. These satellites are being launched at a record pace and have roped big players into this aerospace segment. Astro Digital is a company that risen to the challenge of land mapping and hazard detection using CubeSats.
The 2017 Automotive Testing Expo provided a full display of Sentek Dynamics’ latest environmental testing capabilities. Not only was a simultaneous 3-axis vibration test system on display, it was paired with a Crystal Instruments Spider-81 multi-axis capable vibration controller as well.
Sentek Dynamics is pleased to announce the opening (effective July 2017) of its first Russian office. Located in the city of St. Petersburg, Russia, Sentek Dynamics chose this site due to its unique combination of both culture heritage and industrialized technology subdivisions.
This past month (June 20th, 21st, and 22nd) Sentek Dynamics along with controller company Crystal Instruments attended the European Automotive Testing Expo in Stuttgart Germany. Over 6,000 attendees came out to visit more than 300 exhibitors. There was a wide variety of testing equipment displayed at each of the exhibits; it ranged from virtual-reality driving simulators to test and measurement devices including temperature chambers, shakers, and vibration controllers. Sentek Dynamics and CI together showcased the largest of their L-Series shakers along with a Spider-81 Vibration Controller.
Recently, the Sentek Dynamics Team commissioned a Sentek Dynamics THV Series AGREE Chamber* at a major US aerospace company. An identical chamber is scheduled to be commissioned at the company’s Canadian facility in August 2017.
ASTM transportation tests (such as ASTM D4169) are commonly used to simulate vibrations induced by the shipping of containers via truck, air, and rail. Often times these tests require very low level random vibration profiles which can be hard to run and control. On top of that, many of the profiles begin as low as 1 Hz, which can cause problems as well.
Electro-dynamic shakers are by nature robust and durable pieces of testing equipment. Frequently, they are not given much thought until a problem arises. When these problems do happen, they can be costly; not only monetarily but also in lost labor hours and downtime. Regularly scheduled preventative maintenance programs can help prevent unexpected problems and maintain peak testing performance.
The phrase “Good things come in small packages” is true! Small satellites, also known as CubeSats, are being launched at a record pace with the successful February 15, 2017 launch of 104 satellites of which 88 were Planet Labs’ Dove satellites collectively known as Flock‐3p, aboard an Indian Space Research Organization (ISRO) Polar Satellite Launch Vehicle (PSLV) rocket from the Satish Dhawan Space Center in Sriharikota, India. This amazing launch followed the successful June 22, 2016 launch of 12 Planet Labs’ Flock‐2p satellites from the Satish Dhawan Space Center. These spacecraft are shoebox‐sized satellites placed into lower Earth orbit to provide imaging data.
The Sentek Dynamics team enjoyed meeting attendees at the 2016 Automotive Testing Expo in Novi, Michigan. Visitors stopping by the booth were able to preview a complete vibration test system provided by Sentek Dynamics.
Sentek Dynamics hosted its Fall 2016 Sales and Training Meeting for North American Representatives September 19 – 21, 2016 at its offices in Santa Clara, CA. Participants learned about new products and gained hands-on experience with electrodynamic vibration test equipment using an 11,000 lbf Sentek Dynamics’ demonstration system and Crystal Instruments’ controller.
Sentek Dynamics completed the installation of a 14,300 lbf water-cooled system with a 60x60 inch high-pressure slip table and 60x60 inch head expander with load support and guidance at a major Silicon Valley technology company. Systems features included a long-stroke option (3.0 inch) and air-isolation mounts to eliminate the need for a seismic floor.
Sentek Dynamics and our sister company Crystal Instruments was recently featured in the March 2016 issue of Sound & Vibration magazine. Click on the picture below to download a full copy of our featured article, "What's Required to Bring Vibration Testing In House?".
In the new flick The Martian, vibration testing becomes a matter of life and death, survival or starvation, when a supply probe bound for Mars and loaded with nourishment for our lonely red planet hero (Matt Damon) fails mid-launch. Prepare for movie spoilers.
Sentek Dynamics and its sister company Crystal Instruments participated in the thirteenth Automotive Testing Expo North Americadisplaying their latest products and technologies designed for today’s demanding environmental test requirements that ensure manufacturer’s products meet the highest standards for product quality, reliability, durability and safety.
