Abstract: A controller of a hob is connected to a temperature sensor of a radiation based heating element. In principle, two different groups of temperature sensors can be used, whose resistance values differ by approximately a factor of three. When the hob is first used, the resistance of the temperature sensor is measured at room temperature and is classified in one of the two groups of temperature sensors on the basis of a limit value between the two typical temperature profiles of the groups of temperature sensors. On the basis of this, calibration of the controller is carried out for the purpose of adjusting to the established group to which the temperature sensor belongs.

Abstract: A method for precision thermal measurement and control, especially for bioreactors, as well as the correction of temperature sensitive probes such as pH and dissolved oxygen. Typical control requirements are ±0.1° C. The thermal measurement circuit converts a sensor output to a high level voltage or current with great accuracy and provides noise immunity and sensor isolation. While digital outputs from sensor converters can have the greatest noise immunity, the noise associated with digital circuitry may contaminate low level sensor signals so in many cases an analog sensor converter is preferred because of low noise generation, especially if the converter is near the sensor. The circuit is low cost, reliable, generates minimal heat is immune to, and does not generate noise, and requires minimal calibration effort.

Abstract: An externally powered temperature calibration device includes a system that provides a warning of high temperatures within the device after the device has been disconnected from the external power. The warning system includes a capacitor that provides power to a light-emitting diode (“LED”) after the calibration device has been disconnected from the external power. A temperature sensor monitors the temperature of an internal component. An output signal from the sensor is used to control a switch that connects the capacitor to one of several resistors having different resistances. The switch therefore controls the discharge rate of the capacitor based on the sensed temperature at the time the calibration device was disconnected from the external power. As a result, the period during which the capacitor powers the LED can be commensurate with the time required for the internal component to cool from its initial temperature.

Abstract: The output of a solid-state temperature sensor is the ratio of a voltage proportional to a reference voltage. The solid-state temperature sensor used diodes in its sensing and reference circuits, however, these diodes exhibit a second order behavior that causes the temperature sensor output response to deviate from an ideal straight line. This output response deviation has a characteristic error curve that is shaped like a parabola. An offset that varies opposite to that of the temperature sensor output response deviation may be determined and applied in the digital domain as offset compensation after the temperature has been conversed to a digital value with an analog-to-digital converter (ADC). By adding this offset compensation to the digital output of the ADC, digital representations of the measured temperatures will track more linearly.
