Vibration Controller

Vibration controller used high performance processor with low-noise analog technology, achieves high performance and high reliability.

 

It comes with an all-in-one input interface and adapts to a variety of sensor input. The safety output protection circuit is present to protect the safety of the test piece and the test system. With excellent control performance and control accuracy, 3200 lines and lowest swept sine of1Hz makes it an ideal controller. It also comes with a network communication interface and convenient remote monitoring.
