Abstract
A sensor element and a method for producing a sensor element are disclosed. In an embodiment a sensor element for temperature measurement includes a ceramic carrier and at least one NTC layer printed on the carrier, wherein the NTC layer covers at least part of a surface of the carrier, and wherein the sensor element is designed for wireless contacting.
Claims14
A sensor element for temperature measurement comprising:
- a ceramic carrier;
- and
- at least one NTC layer printed on the carrier,
- wherein the NTC layer covers at least part of a surface of the carrier,
- wherein a resistance of the NTC layer is determined by a number of printing operations,
- wherein the sensor element is designed for wireless contacting,
- wherein the sensor element is an NTC thick-film sensor,
- wherein the NTC layer has a recess, and
- wherein the recess is setting a predetermined resistance value of the NTC layer.
6 more elements
A method comprising:
- providing a ceramic carrier material;
- at least partially printing a surface of the carrier material with an NTC paste to form an NTC layer, wherein printing comprises performing at least one printing operation directly on the surface of the carrier material, and wherein a resistance of the NTC layer is determined by a number of printing operations;
- sintering the carrier material and the NTC paste in a common sintering operation;
- partially removing the NTC layer so that a predetermined resistance value is set;
- and
- sputtering thin-film electrodes on the NTC layer.
