Claims17
A heater module, comprising:
- a heater assembly comprising a heater and a temperature sensor thermally coupled to the heater;
- and
- a trimmable resistor electrically coupled to the temperature sensor or to the heater wherein the heater assembly is embodied as a thick-film heater element, and wherein the temperature sensor comprises a conductor embedded in a substrate of the heater element.
A method of manufacturing a heater module, method comprising:
- bringing a temperature sensor into thermal contact with a heater to form a heater assembly;
- electrically coupling the temperature sensor to a trimmable resistor;
- and
- trimming the trimmable resistor to adjust a combined resistance of the temperature sensor and the trimmable resistor to a predetermined value.
