Abstract
A magnetic field sensor housed in a cooling device has an inner core body for measuring the behavior of a charge put in a shaft furnace, an inner casing for accommodating the inner core body therein, and an outer casing for accommodating the inner casing with a space for a circulating path of cooling medium therebetween. The inner core body consists of an exciter for exciting the charge put in the furnace, a magnetic field sensing member arranged in front of the exciter for detecting the exciting magnetic field generated from the exciter and a driving circuit arranged at the rear of the exciter for driving the sensing member.
