The BT Series shakers from Sentek Dynamics 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 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.
The BT Series is recommended for vibration testing of small assemblies and components. These shakers have armature diameters from 60 mm (2.36 in.) to 120 mm (4.72 in.). The BT-1000 is equipped as standard with Automatic Armature Centering (AAC) and Air-Isolation Feet (AIF).
The BT-M and BT-MTH Series are our modal shakers lines. BT-M will use standard stingers while the BT-MTH is our through-hole version. On the 100 N and 200 N system the BT-MTH offers over double the displacement. The BT-MTH Series allow you to use piano-wire stingers. The BT-1000-M is ideal for the structural and modal analysis of high-mass structures. The addition of ZPR (electronic zero-point regulation and adjustable suspension stiffness) allows the user to pre-load the structure prior to applying a dynamic load.
The new Sentek Dynamics Bench Top and modal exciters are based upon years of practical experience. These systems all exhibit a high lateral stiffness and high force-to-weight ratio. They are specifically designed to help ensure the best possible performance with minimum setup time.
