High-temperature detector and method of producing the same

A hybrid high-temperature detector comprising:

• a high-temperature sensor comprising a high-temperature measuring film, a first connection made of a high-temperature-stable material and a second connection made of a high-temperature-stable material, the connections being connected to the high-temperature measuring film;
• an elongate housing comprising a first elongate ceramic substrate, a second elongate ceramic substrate and a third elongate ceramic substrate, the elongate ceramic substrates being interconnected, the first elongate ceramic substrate being arranged between the second elongate ceramic substrate and the third elongate ceramic substrate and including a through-hole which is located adjacent a first end of the housing and in which the high-temperature sensor is arranged, the second and third ceramic substrates being arranged such that the hole in the first ceramic substrate is fully covered;
• a first conductor track consisting of a high-temperature-stable material on the second elongate ceramic substrate, the first conductor track being connected to the first connection of the high-temperature sensor and extending in the direction of a second end of the housing;
• a second conductor track consisting of a high-temperature-stable material on the third elongate ceramic substrate, the second conductor track being connected to the second connection of the high-temperature sensor and extending in the direction of a second end of the housing;
• and
• a connection point located adjacent the second end of the housing and adapted to have connected thereto electric leads via a non-high-temperature-stable material, a signal produced by the high-temperature sensor being adapted to be tapped via the connection point.
