MVT-1000
Mössbauer Velocity Transducer

MVT-1000 is the top model of the WissEl velocity transducer line. It is equipped with NdFeB and SmCo5 high field magnets. The solidly built construction, based on a massive steel housing, furthermore the small moving mass and the power of its drive magnet system, make it suited for operation in a wide velocity range. Equipped with high velocity springs and controlled by a high velocity drive unit it can reach velocities of far more than 1000 mm/s  (see High Velocity Drive Systems ) .
Due to its very compact design and the absence of magnetic fringe fields in the middle of its drive tube, the MVT-1000 is very well suited for bidirectional Mössbauer sources (details on request).
