Abstract

The present invention relates to a sensor for measuring magnetic fields in extreme conditions, particularly at high ambient temperatures and under exposure to intense ionising radiation. The invented sensor consists of a sandwich structure of substrates (1) made of ceramic material. In the gaps between the substrates (1) in the sandwich structure, fired printed surface patterns (2, 3, 8) are formed on the substrates (1), which form the individual turns of the resulting measuring coil of the sandwich structure. The manufacturing process for the invented sensor is simple, as surface patterns are first printed onto individual substrates (1), which are then fired, and subsequently the substrates (1) are assembled into a sandwich structure, fixed by means of fixation points (5, 6), and the sandwich structure is then hardened by re-firing. Part of the invention is the structure of the fired patterns, which allows the sensor to achieve maximum separation of a useful signal in the sensing axis relative to other axes and to resist other physical effects caused by radiation.
