Abstract(in Japanese) (See Japanese page)
Abstract(in English) This new type current senser has superiority in two points. The one is degitalized from its messuring parts. The other is rather less expensive in cost. We settle a shutter on the vibrater influenced by magnetic field of alternating current, and the velocity of the vibration changes according with the strength of electric current. This is the basic idea of this new senser. We can cut down the cost s because It is easy and cheep to measure accurately the time of the shutter the interrupting the light by modern circuit technology. Old sener are analogue type. This new one is superior in its accuracy, durability and meny other point, because we adopted themethod tomessure the interval of pulses in digital.
