RL-C21
State-of-the-art vibration control and data acquisition system. The system is distinguished by simplicity, reliability and high safety standard. The controller has a modular scalable architecture, which allows the user to get from 1 to 32 input channels.

The configuration of RL-C21 system is flexible: it is determined by the user and can be modified at any time.

The most innovative techniques of digital signal processing are embedded in the system. All calculations and safety checks are run by a DSP directly in the controller. This feature provides the highest level of shaker protection.

The system enables running multishaker tests and successfully controls two- and three-axes shakers, as well as vibration shakers with up to 6 degrees of freedom.

The presence of a galvanic isolation in the input chains allows effectively protecting input chains from breaks.

RL-C21 is used with a specialized vibration test software package VisProbe SL.

How to mount accelerometers

To provide high accuracy of vibration measurement, the usable frequency and dynamic range must not be limited as a result of incorrect mounting of accelerometers. One of the basic requirements for correct sensor mounting is close mechanical contact between the accelerometer’s base and the mounting surface. To achieve it, you can use a wide range of various special applications for mounting. However, it is not that simple.

Multishaker tests in RL-C21 and RL-C25. Theory and application.

Multishaker tests have recently gained popularity for tests of large objects, which cannot be placed on one shaker, or for simultaneous vibration impact on the object on several axes. This approach allows imitating the actual vibration conditions of operation more closely.
