20 - 1000 N (4.5 - 224.8 lbf)

The BT Series compact, lightweight, and powerful permanent-magnet benchtop shakers from Sentek Dynamics are ideal for general-purpose small-component vibration testing. The bench top shaker system’s efficient stand-alone design combines internal signal generators and integrated or external compact amplifiers for easy transportation and set-up for a range of applications. The benchtop shakers are perfect for frequent conveyance to different test locations and are powerful tools for educational and research purposes in both laboratory and industrial environments. Most vibration controllers and signal generators can be utilized to easily send excitation signals to the shakers by way of a BNC connector. The simple design and broad applicability of these systems make them an essential tool for any organization looking to develop or expand their in-house vibration testing capabilities.

Common uses: Vibration testing, Mechanical impedance measurements, Educational demonstrations, Structural response testing, Vibration transducer calibration

Useable frequency range up to 15,000 Hz
Compact light-weight design for easy transportation
Internal signal generator available for standalone use
Adjustable trunnion base for shaker barrel rotation
