Measurement of the radial deviation on superconducting magnets
At the Institute for Solids and Materials Research Measurement system requirements
(IWF) Dresden a motor with magnetic bearings has - Measuring range: 1 mm
been developed using high temperature - Accuracy: 2 µm
superconductors which can be employed for feed - Resolution: 2 µm
pumps for liquid nitrogen. The most important - Bandwidth: 100 Hz
application of superconducting permanent
magnets is the superconducting magnetic bearing. Reasons for the system selection
For the measurement of the radial deviation of The special temperature compensation enables
these magnetic bearings, U1 eddy current sensors measurement at the lowest temperature and also
with special temperature compensation for -196 °C at room temperature.
and 20 °C are used in the evacuated and cooled
ambient. Ambient conditions
- Temperature: -196 °C ... +20 °C
- Medium: Nitrogen or air
- Interference fields: Strong permanent magnet
