Patent KR-20000057319-A (KR)
Inventor: NIGHTHART CLAUS-WIRGEN
IPC: G01P1/07
Filed: 1997-11-27
Abstract: PURPOSE: An eddy current measuring apparatus is provided to reduce the size with a lower cost by reducing the second torque transmitted to a pointer shaft or constantly maintaining the first torque transmitted to an eddy current member. CONSTITUTION: A rotational magnet(8) is fixedly arranged to be rotated in a driving shaft, positioned opposite to an eddy current member, fixed to be rotated on the pointer shaft, and transmits a first torque to a pointer shaft in case that the driving shaft is rotated. A torsion spring(11) transmits to the pointer shaft a second torque in an opposite direction with respect to the first torque. A compensating unit(14) reduces the second torque transmitted to the pointer shaft(10) based on the torsion spring(11) or constantly maintains the first torque transmitted to the eddy current member(9).
