RASDELTA MEASUREMENT BOARDS

Do you have many and different measurements, which vary depending according to the application? Then benefit from our modular and flexible RASdelta measurement boards! We offer you a comprehensive and application-oriented measurement data acquisition of torsional vibrations, temperature, acceleration, velocity and sound. Depending on your requirements, you can interchange the powerful boards and adapt them to your measuring device.

RASdelta Trigger BOARD

The powerful RASdelta trigger board synchronizes all measurement data between channels, acquisition modules and connected front-ends. It is an integral part of the RASdelta.

RASDELTA ANALOG BOARD 3,2 MHZ

With the RASdelta analog board, you can measure analog quantities such as airborne and structure-borne noise, acceleration, temperature, displacement or pressure. These quantities can be used, for example, to determine the position of a sound source or to carry out detailed valve train or cylinder pressure investigations. The analog measurement data is acquired by equidistant sampling.
