Thiết bị thử nghiệm rung động Labworks LW139.138-40

The LW-139-40 system utilizes the Labworks ET-139 shaker in a lower force output system. Suitable for larger loads that don't require high vibration levels, this system offers the benefits of the larger shaker in a reduced price system. The shaker's full 1-inch armature stroke capability is ideal for many modal as well as low frequency general applications. The air cooled PA-138 amplifier is direct coupled to the shaker to give the maximum performance at low and high frequencies and can be easily switched from voltage source mode for general testing to current source mode form modal testing applications. A voltage-proportional-to-output-current output signal is provided for modal test and other applications requiring force monitoring. Dual meters display the system operating levels and comlete shaker and user interlocks help protect the system from accidental abuse.
