Compact vibration measuring system
for the development of magnetic resonance tomographs

M7 laser sensor  

Inside of magnetic resonance tomograph, strong magnetic fields are generated by large magnetic coils. The forces arising from high currents may lead to audible and tactile vibrations of the tomograph. For the patient, laying inside the apparatus these occurrences are very disagreeable.

Around the magnetic resonance tomograph mustn´t be any freely movable metallic objects, they would be pulled into the machine. For this reason, a lot of measuring devices are not usable at this place. The researchers of Siemens AG were looking for a very compact vibration measurement system, to record, store and wirelessly transmit the oscillations of the apparatus during normal operation.

Always the two axis of the magnet coil package should be measured at a time.
 

We supplied
•  2 M7 sensors
•  1 i-control
•  1 4-channel A/D converter
•  Ethernet network
•  2 x RS232
•  Profibus DP
•  Test software

The i-Control can optionally be provided with control units for laser scanners or with 4-channel A/D converters (up to 2).

With the A/D converter board 2 intensity signals and 2 sensors can be recorded at the same time.

Of course, laser sensors and laser scanners can be concurrently connected too, a corresponding mounting of the i-Control unit is provided. With this flexibility, the i-Control is qualified for all conceivable acqusition and measuring tasks.
