Claims24
A heater module comprising a thick-film heating element, the heating element comprising:
- a heating conductor;
- a temperature sensor;
- and
- a substrate supporting the heating conductor and the temperature sensor;
- wherein the heater module comprises a resistive conductor having at least one trimming cut formed by a trimming process and the resistive conductor is mounted on the heating element.
A method of manufacturing a heater module comprising a thick-film heating element, the heating element comprising a heating conductor and a temperature sensor supported by a substrate, the method comprising removing material from a resistive conductor of the heater module to increase a total resistance of the temperature sensor and the resistive conductor, or a total resistance of the heating conductor and the resistive conductor, to a predetermined value.
A heater module comprising a thick-film heating element, the heating element comprising:
- a heating conductor;
- a temperature sensor;
- and
- a substrate supporting the heating conductor and the temperature sensor;
- wherein the heater module comprises a resistive conductor having at least one trimming cut formed by a trimming process
- wherein the temperature sensor comprises the resistive conductor and
