Abstract
The invention relates to a temperature probe which comprises a functional ceramic probe element and a ceramic housing. The probe element is mounted in the ceramic housing so that at a face of the probe element has direct and form-fitting contact with the ceramic housing. The invention further relates to a method for producing a temperature probe.
Claims21
A temperature probe, comprising:
- a functional ceramic sensor element;
- and
- a ceramic housing, wherein the ceramic sensor element is arranged in the ceramic housing;
- a temperature sensor comprising two contact elements, the two contact elements being located on opposite sides of the ceramic sensor element, wherein each contact element is electrically connected to the ceramic sensor element;
- wherein the ceramic housing comprises a cavity with a recessed region, wherein side walls and a bottom wall of the recessed region are defined by a ceramic material of the ceramic housing;
- wherein the ceramic sensor element is located at least partially in the recessed region, and wherein the contact elements are located sideways from the recessed region in a top view and do not protrude into the recessed region.
3 more elements
A method for producing a temperature probe, comprising:
- providing a functional ceramic sensor element comprising electrodes;
- providing contact elements;
- preparing a ceramic raw material and forming the ceramic raw material into a green body using an injection molding method;
- sintering the green body to form a sintered ceramic housing;
- wherein the sintered ceramic housing comprises a recessed region, wherein side walls and a bottom wall of the recessed region are defined by a ceramic material of the ceramic housing;
- and
- arranging the sensor element in the sintered ceramic housing so that the sensor element is at least partially located in the recessed region and arranging the contact elements at positions located sideways from the recessed region in a top view such that the contact elements do not protrude into the recessed region and the contact elements are electrically connected to the sensor element.
4 more elements
A method of making a temperature probe, comprising:
- providing a functional ceramic sensor element and contact elements;
- and
- arranging the ceramic sensor element in a ceramic housing, wherein the ceramic housing comprises a recessed region, wherein side walls and a bottom wall of the recessed region are defined by a ceramic material of the ceramic housing;
- arranging the contact elements in the ceramic housing at opposite sides of the ceramic sensor element at positions located sideways from the recessed region in a top view on the bottom wall such that the contact elements do not protrude into the recessed region after arranging the ceramic sensor element at least partially in the recessed region;
- and
- electrically and mechanically connecting the contact elements with the ceramic sensor element by burning in a metallization paste inside the housing.
