Abstract
A temperature sensor is described that comprises a temperature sensing element, a substantially thermally insulating substrate having a first side and a second side and at least one layer of substantially thermally conductive material coated on the first side of the substrate. A first hole is provided on the second side of the substrate and the temperature sensing element is arranged to sense temperature within the first hole. A plurality of additional holes may also be provided on the second side of the substrate, these holes may be coated to aid thermal transfer. The temperature sensing element may be a thermocouple. The temperature sensor may be included in a temperature measurement probe for use in measuring the temperature of workpieces produced using a machine tool.
Claims24
A temperature sensor comprising;
- a temperature sensing element;
- and
- a substantially thermally insulating substrate having a first side and a second side;
- wherein the first side of the substantially thermally insulating substrate carries a coating that comprises at least one layer of substantially thermally conductive material,
- wherein a first hole is provided on the second side of the substrate and the temperature sensing element is arranged to sense temperature within the first hole.
A method of manufacturing a temperature sensor comprising the steps, in any suitable order, of;
- (i) taking a thermally insulating substrate having a first side and a second side;
- (ii) coating at least one layer of substantially thermally conductive material on to the first side of the substrate;
- (iii) forming a first hole on the second side of the substrate;
- and
- (iv) placing at least part of a temperature sensing element within said first hole.
