Research into new-technology batteries has accelerated over the last decade with the promise of energy density being significantly improved.  This research has led to more lithium-ion battery applications in aircraft, electric and hybrid vehicles (EVs and HEVs), 2 and 4-wheel light electric vehicles (LEVs) and personal items such as laptops and wearable devices.

Sentek Dynamics is proud to announce the expansion of the THV Series Environmental Test Systems. Paired with its proven line of electrodynamic shakers, the Sentek Dynamics THV Series now offers thirteen standard chamber sizes to meet customer requirements for combined temperature, humidity and vibration (THV) testing applications

Sentek Dynamics will be hosting its 4th International Sales Meeting to commemorate another successful year of sales, provide training on new Sentek Dyanmics’ products and give a sneak peek into exciting upcoming projects.

Sentek Dynamics’ TC (temperature only) and TCH (temperature/humidity) Series Environmental Test Chambers expand a test chamber product line that includes the THV (temperature/humidity and vibration) Series AGREE (Department of Defense’s Advisory Group on Reliability of Electronic Equipment) chambers.  The TC and TCH Series from Sentek Dynamics are uniquely designed and built for long-life performance and enhanced functionality to suit the needs of global testing standards.

Medical device manufacturers are aiming to improve healthcare and automate surgical processes. The exponential leap in innovation made by medical device manufacturers and the quick adoption of their technology and products by the healthcare industry, has led to the need of ensuring that their products not only serve their purpose, but are also extremely safe and reliable

Sentek Dynamics’ PA Series replacement power amplifiers are available for most other vibration test equipment manufacturers obsolete, inefficient power amplifiers.  The PA Series amplifiers are nearly twice as efficient as older air and water-cooled amplifiers and provide a significant savings in power consumption and electrical bills.  So significant, in fact, that the savings can offset the cost of a replacement amplifier in a very short period. 

This past week, the Sentek Dynamics’ Field Service Team completed installation of Sentek Dynamics’ third-largest water-cooled electrodynamic shaker! This extra-high force Model E20064A shaker with a PA4200 power amplifier offers a rugged and proven solution for large payloads and demanding testing requirements.  It will be used by an exciting new leader in energy generation for product development and qualification testing.

Modal Testing is carried out to understand the dynamic behavior of structures. The procedure is to excite the structure or device under test (DUT) with a force of known frequency and amplitude. The response is then analyzed by measuring the output of strategically placed accelerometers. Using the data acquired from the accelerometers, a modal model of the structure or DUT can be constructed. From the derived model, modal parameters, including resonant frequencies, mode shapes, and damping values can be determined.
