Sentek Dynamics Inc. products

The L-Series air-cooled electro-dynamic shakers are designed for the vibration testing of small electronic or mechanical components or other assemblies up to 200 kg (440 lb).

Sentek Dynamics’ PA Series air-cooled, digital switching power amplifiers utilize an intelligent logic control system that assures maximum performance, safety, and reliability.  Standard amplifier outputs range from 1 to 480 kVA.  Interlocks to prevent shaker damage or operator injury include: Over-voltage, Over-current, Amplifier Over-temperature, Shaker Over-temperature, Over-travel, Phase Failure, and Power-module Fault.  The amplifier provides drive power to the shaker, field coils, blower unit and other ancillary components.

Lengthy and heavy devices require dual excitation shaker systems for vibration testing. Dual excitation shaker systems typically consist of two shakers with horizontal or vertical orientations. Dual excitation shaker systems enable the testing of long and heavy UUTs in the Horizontal Push-push, Push-pull and Vertical configurations.

Real-world vibration happens in all directions and thus it is necessary to test the DUT in all three directions simultaneously. The MA Series of three-axis shakers is designed and manufactured for this testing purpose.
