PowerProbe builds on the success of the MagiDrive as the premier magnetically coupled UHV rotary feedthrough. This coupling forms the basis of the PowerProbe sample transfer arm range, providing linear or combined linear and rotary motion within ultra high vacuum. These unique probes avoid the limitations of conventional designs, offering up to an order of magnitude improvement in key aspects of performance.
PowerProbes have unrivalled transmission performance. The standard linear coupling has a breakaway force of 180 N (40lbf) in comparison to the 26-50 N of our nearest competitors. A high power option is also available with a staggering 310 N (69lbf).
In the attached figures, the axial stiffness chart shows that the coupling on the standard probe deflects by less than 1 mm for a 98 N (22lbf) load.
Features
- True UHV performance
- Linear or linear/rotary motion
- High power coupling
- Bakeable to 250 °C
- Unrivalled performance
The rotary transmission is essentially based upon the MD35 MagiDrive, delivering over 4Nm of breakaway torque. This is four times the leading competitor. The unique rotary coupling retains the angular rigidity of the MagiDrive series.
The probe deflection chart shows the deflection characteristics at the end of a horizontally mounted PowerProbe arm as a function of the extended length, and with an applied load of 10 N. The relationship between load and deflection is approximately linear for typical transfer loads.
