Bench Top Shakers (BT-Series)
100 – 1000 N (70 – 224 lbf)
The BT Series shakers are designed for demanding vibration test applications. Typical applications included structural analysis, calibration and testing of smaller assemblies. The BT-100 through BT-400 shakers utilize light weight rare earth magnets in lieu of traditional Alnico magnets. The use of these magnets decreases the total shaker mass to a third of similar size system, making these shakers easy to handle and portable.
The line of Sentek Dynamics Bench Top shakers is based upon years of practical vibration test experience. These shakers all exhibit a high lateral stiffness, high force-to-weight ratio and are specifically designed to help ensure the best possible performance with minimum setup time.
Uses: Vibration testing; Mechanical impedance measurements; Educational demonstrations; Structural response testing; Vibration transducer calibration; Testing of small electronic assemblies and components.
The mini-shaker is a small, portable permanent magnet exciter with an integral power amplifier. The design eliminates the need for a separate, inconvenient power amplifier. The excitation signal can be connected directly to the BNC connector from most vibration controllers or
signal generators. The mini-shaker is perfect for frequent conveyance, and educational and research purposes in both lab and industrial environments.
Uses: Vibration testing; Mechanical impedance measurements; Educational demonstrations; Structural response testing; Vibration transducer calibration
Modal Bench Top (BT-M Series) Shakers
The Modal Bench Top (BT) Series exciters are designed specifically for structural and modal analysis applications. The BT-100-M through BT-400-M shakers utilize light weight rare earth magnets in lieu of traditional Alnico magnets. The use of these magnets decreases the total shaker mass to a third of similar size system, making these shakers easy to handle and portable. The BT-100-M through BT-400-M are also available in a through hole version (MTH) with displacements up to 25.4mm or 1 inch.
The BT-1000-M is for structural and modal analysis applications of high-mass structures. The exciter provides 45mm or 1.77 inches of displacement. This system includes electronic zero point control with electronically adjustable suspension stiffness (ZPR).
The line of Sentek Dynamics Bench Top modal exciters is based upon years of practical experience. These systems all exhibit a high lateral stiffness, high force-to-weight ratio and are specifically designed to help ensure the best possible performance with minimum setup time.
Uses: Structural response testing; Modal analysis
