High-temperature detector and method of producing the same

Abstract

A high-temperature detector comprises a temperature sensor comprising a high-temperature measuring element, a first connection and a second connection which are made of a high-temperature-stable material and which are connected to the measuring element. The high-temperature sensor is arranged in an elongate housing adjacent a first end thereof, and the housing comprises a first and a second conductor track produced from a high-temperature-stable material, the conductor tracks being connected to the first and second connections and extending in the direction of a second end of the housing. Furthermore, a connection point is provided, which is used for tapping a signal produced by the high-temperature sensor and which is arranged adjacent the second end of the housing. In order to produce such a device, the sensor is first provided and subsequently arranged in an opening of a first substrate adjacent a first end of the substrate. Following this, a second and a third ceramic substrate are fused with the first ceramic substrate so that the conductor tracks arranged in the second and third ceramic substrates are connected to the connections of the sensor, the conductor tracks extending to a respective second end of the second and third ceramic substrates.
