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). | SPECIFICATIONS | General Specifications | Magnets | NdFeB and SmCo5 | Housing | Steel, nickel plated | Guide springs | Fiberglass enforced epoxi | Velocity Range | 0 ... +/- 300 mm/s (0 ... > 1000 mm/s in high velocity version) | Resonance frequency | ~ 25 Hz | Calibration constant | ca. 25 mm/s per Volt | Accuracy (at resonance frequeny and normal load) | +/- 0,5 %o in a sinusoidal mode +/- 1,5 %o in a triangular mode | Linearity | better than 0.15 % up to +/- 100 mm/s | | Physical | Length | 138 mm | Diameter | 108 mm | Weight | 4.5 kg | | | | |
