摘要

Capacitive force transducers have been developed and used for monitoring the coil pre-stress during assembly and excitation of several dipole models for LHC. Tyically these gauges are strips several tenths of millimeter thick that can be made according to a large variety of geometries. Inserted between two surfaces, they allow to measure the distribution of contact pressures up to 200 MPa from ambient temperature to superfluid helium also in presence of a static magnetic field. The sequence and quality of the manufacturing steps are determining factors in the performance of this kind of gauges. The paper describes the basic principles, possible configuration geometries, fabrication and calibration procedures. Finally the applications of capacitive gauges in the framework of the R&D programme of superconducting short dipole models for LHC are reviewed and discussed.
