Abstract
Methods for adjusting the resistance of temperature measuring sensors are disclosed, including measuring the resistance for a first heat-sensitive portion of the sensor at a first predetermined temperature, measuring the resistance for a second heat-sensitive portion of the temperature measuring sensor at a second predetermined temperature, determining the overall resistance for the temperature measuring sensor from these measured values, and adjusting the resistance of the second heat-sensitive portion so that the overall resistance for the temperature measuring sensor substantially corresponds to the predetermined resistance value. Temperature measuring sensors are also disclosed, including an electrically non-conductive base, first and second heat-sensitive materials applied to first and second portions of the electrically non-conductive base, the second heat-sensitive material being substantially less sensitive to variations in temperature than the first heat-sensitive material, and an electrical contact portion applied to the electrically non-conductive base, so that the first and second heat-sensitive portions are in substantial juxtaposition with each other, with the electrical contact portion therebetween.
