| MR-260A |
 Mössbauer Drive Unit |
 |
The Mössbauer Drive Unit MR-260A is used to control the source motion of Mössbauer Velocity Transducers. It can be operated together with all WissEl transducer models. An error minimisation facility of the Drive Unit MR-260A provides a high precision of the source motion. By means of this facility the velocity transducer can be operated not only in its resonance frequency, but in the whole frequency range of approximately 1 ... 100 Hz. The deviation of the motion from its ideal value is indicated by a LED bar with a logarithmic scale.
