摘要： A temperature sensing circuit a switched capacitor circuit selectively samples ΔVbe and Vbe voltages and provides the sampled voltages to inputs of an integrator. A quantization circuit quantizes outputs of the integrator to produce a bitstream. When a most recent bit of the bitstream is a logic zero, operation includes sampling and integration of ΔVbe a first given number of times to produce a voltage proportional to absolute temperature. When the most recent bit of the bitstream is a logic one, operation includes cause sampling and integration of Vbe a second given number of times to produce a voltage complementary to absolute temperature. A low pass filter and decimator filters and decimates the bitstream produced by the quantization circuit to produce a signal indicative of a temperature of a chip into which the temperature sensing circuit is placed.

摘要： A disclosed linearization circuit includes a reference component, a charging and discharging controller, and a comparator circuit. The reference component has a non-linear dependence on current or voltage. The charging and discharging controller is configured to control alternating charging and discharging of the reference component. A voltage associated with the reference component forms a reference signal. The charging and discharging are controlled such that the reference signal has a periodic time dependence. The reference signal and a measurement signal are received by the comparator circuit. The comparator circuit is configured to generate and output a square-wave signal based on a reference time point during a charge-discharge cycle, and based on a result of a comparison of the reference signal with the measurement signal, such that the square-wave signal represents a linearized output signal. This disclosure further relates to a corresponding method.

摘要： A method for detecting an influence of microwaves on a measurement value of a temperature sensor of a core temperature probe of a cooking appliance, includes: recording the measurement value of the temperature sensor; determining the slope of the course of the recorded measurement values in at least one analysis interval (A, B) which is in a predetermined relation to a switch-on time and/or a switch-off time of a microwave generator; determining whether the slope lies above or below a predefined threshold; interpreting the exceedance of or falling below the threshold to the effect that the corresponding temperature sensor is not located in a food to be cooked and/or the core temperature probe is not correctly inserted into the food or into a receptacle provided for the same.

摘要： A temperature sensor approximates fluid temperature averaged across a location range by including an outer armour layer. Several resistance temperature detectors are spaced in an electrical circuit which is then protected in the outer armour layer. The outer armour layer is woven without any seam to enhance its longitudinal thermal conductivity. In the preferred weave, twenty-four stands of sixteen metal threads each are helically woven. The electrical circuit is sealed interior to the armour layer so any condensation or moisture within the armour layer does not affect the circuit. The armour layer is sealed on its ends to the sheathing of the underlying circuit, so the armour layer provides stress relief across the connections of the resistance temperature detectors to the circuit. The resulting sensor is robust and durable, as well as very flexible.

摘要： The circuit configuration for sensing when a critical temperature of a component has been exceeded makes use of at least one sense transistor which has a temperature-dependent current/voltage characteristic and which is thermally connected to the component. A current source is connected in series with the sense transistor. A circuit device for compensating for parasitic leakage currents at the sense transistor is provided. The circuit device has a measurement transistor and two current mirror circuits. By compensating for leakage currents, the proper operation of the temperature sensor is guaranteed over the entire temperature range and the destruction of the component is prevented.

摘要： The present invention described a signal conditioner. A thermocouple produces a signal that is present at a summing node input of a conditioning amplifier. The conditioning amplifier has a plurality of selectable gain values by which amplifier sensitivity may be varied to complement that of the thermocouple. Provision is made at the summing node input of the summing amplifier for thermocouple cold junction compensation and range offset. The present invention finds application in monitoring thermal conditions in an industrial process, such as a nuclear reactor. The high degree of precision and reliability required in such processes is maintained by including a test circuit which provides a selectable test pulse to the summing node input of the conditioning amplifier. One aspect of the present invention is the provision for testing during actual circuit operation in a process and irrespective of selected conditioning amplifier sensitivity. An additional aspect of the present invention is the inclusion of a summing node wherein various characteristics of conditioning amplifier contour may be independently adjusted without degradation or interference of one characteristic with the other.
