PURPOSE:To form a field remote measuring equipment and a rotary transformer integrally and miniaturize them preventing electric power transmission from fluctuating, by containing the main section of the equipment in a hollow cylindri cal case of magnetic substance, and by forming the rotary transformer on the outer peripheral face of the case. CONSTITUTION:The main section package 1 of a field remote measuring equipment is contained in the hollow section of a hollow cylindrical case 2 made of magnetic substance. On the outer peripheral face of the case 2, the secondary coil 7 of a rotary transformer is integrally wound up. Via a specified space, the coil 7 is arranged to confront a primary core 9 wound up with the primary coil 10 of the rotary transformer. In this manner, the field remote measuring equipment and the rotary transformer can be integrally formed, and so they can be easily put together even if the space of the field magnet section is small. The case 2 has electromagnetic shield effect and is not influenced by displacement in the direction of a rotary shaft, and so electric power transmitted via the rotary transformer can be prevented from fluctuating. |
