MATRIX TYPE MAGNETIC FIELD MEASUREMENT DEVICE IN RAILWAY CAR

摘要

PROBLEM TO BE SOLVED: To provide a matrix type magnetic field measurement device in a railway car for quickly measuring a magnetic field in the railway car and directly visualizing the state of distribution of the magnetic field by installing a magnetic field measurement apparatus on one surface and a display device on the other surface corresponding to the position of the magnetic field measurement apparatus so as to become a front/rear arrangement.

SOLUTION: The matrix type magnetic field measurement device in a railway car includes the magnetic field measurement apparatus 2 and the display device 4. The magnetic field measurement apparatus 2 and the display device 4 are arranged on one and another surfaces of a common substrate 1 at positions corresponding to each other so as to become the front/rear arrangement, and output from the magnetic field measurement apparatus 2 is converted into an effective value and is analog-output to the display device 4.
