Abstract

The invention relates to a temperature sensor system (100) comprising a first ceramic housing part (200) which has a sleeve-shaped lower part (210) with a first lower end (215) having a first opening (211), and a second upper end (216) having a second opening (212), and an upper part (220) connected to the second upper end (216). The temperature sensor system (100) further comprises a temperature probe element (1) which is at least partially arranged in the lower part (210) and which has a ceramic sensor element housing (3), a sensor element (2) arranged in the sensor element housing (3) and electrical supply lines (4). The sensor element housing (3) is at least partially arranged in the first opening (211). The ceramic sensor element housing (3) has a higher thermal conductivity than the first ceramic housing part (200). Also disclosed is a method for producing a temperature sensor system (100).

Description

Background technique [0001] For example via ceramic heating conductors - thermistor elements (NTC thermistors, "negative temperature coefficient thermistors"), silicon temperature sensors (e.g. so-called KTY temperature sensors), platinum temperature sensors (PRTD, "platinum temperature sensors") resistance temperature detectors") or thermocouples (TC, "thermocouples") in order to monitor and regulate the measured temperature in different applications. [0002] For easy assembly in the application, sufficient mechanical stability, and to protect the own temperature sensor element from external influences, and to avoid corrosion due to aggressive media, it is mounted inside a housing, which is generally made of plastic, of simple metal construction or of Composition of plastic-metal composites. Plug contacts and / or conductor vias are generally integrated into the housing for the electrical connection. A suitable sealing of such systems is achieved using sealing, potting compo...
