Head expanders are commonly used for vertical environmental testing. The purpose of the head expander is to extend the surface area of the shaker top to accommodate units under test (UUTs) with large dimensions for mounting and testing. One of the key parameters is the working frequency range associated with each head expander. The upper frequency is often used instead of the first resonance frequency of the head expander in vibration control tests.

Read MoreSimultaneous 3-axis testing has several unique advantages compared with vibration testing in one axis at a time. The primary advantages include, but are not limited to, the ability to reproduce a real-world environment identical to what the product sees in the field, and significant setup and test time savings compared to individual single-axis testing.

Read MoreElectromechanical actuators are used to control the movement and position of various control surfaces on aircraft. Aircraft flight control surfaces allow the adjustment and control of aircraft flight altitude. Electromechanical actuators are critical components that undergo rigorous safety and reliability testing.
Read MorePID control is a very simple and powerful method for controlling a variety of processes, including temperature. The acronym PID stands for “Proportional, Integral, and Derivative”.
Read MoreA dual 120 kN shaker system was professionally installed this week at a customer’s site. The model installed was a H12056A-PA3130-LST1000M/AAC/MGB/CU-3/CIP vibration test system, which is a 26,437 lbf water-cooled vibration testing system with 2 inch pk-pk displacement, a low-pressure magnesium horizontal slip table, an air-cooled power amplifier, water-cooling unit, interconnecting cables, and hose.
Read MoreIn addition to new vibration testing systems available for immediate delivery, Sentek Dynamics has accepted several trade-ins from existing customers needing additional capacity. Used 50 kN (11,000 lbf) and 65 kN (14,300 lbf) systems were recently added to our inventory.
Read MoreWednesday, 20 May 2020 - Sentek Dynamics, headquartered in Santa Clara, CA is pleased to announce their new Bench Top (BT) Series of shaker systems. The systems range in size from 100 N (70 lbf) to 1000 N (224 lbf). Systems 400 N (99 lbf) and smaller are permanent magnet shakers and use lightweight rare earth magnets, making these systems easy to handle and portable. There are three versions of the BT Series of shakers: the BT, BT-M and BT-MTH.
