A temperature sensor device for sensing a temperature of a surface of an object includes a temperature sensor element being or comprising a thermistor and a housing having a measuring cavity in which the temperature sensor element is disposed. The housing has a measuring surface contacting the surface of the object, an outer shell, an inner shell, and an outer cavity formed between the outer shell and the inner shell. The outer shell, the inner shell, and the outer cavity thermally insulate the measuring cavity and the measuring surface from an environment of the object.

A battery system includes a battery module, thermistor, and ECU. The thermistor detects the temperature of a first area in the battery module. The ECU calculates the estimated temperature of a second area having a higher temperature than the first area in the battery module, by adding a temperature correction amount to a detected value of the thermistor. The ECU is configured to set the temperature correction amount according to a time differential value of the detected value. Then, the ECU sets the temperature correction amount such that the rate of increase of the estimated temperature of the second area does not exceed a predetermined rate that is larger than zero.

Techniques described herein address these and other issues by utilizing two or more sensors to take temperature measurements from which a temperature-differential or instantaneous temperature rate-of-change, can be determined. In turn, this can be used to make a highly accurate model of the relationship between the temperature, temperature-differential, and clock circuitry frequency, to accurately estimate the frequency rate-of-change for frequency correction/compensation.

Temperature-sensor calibrating method enables reusing the thermometer main unit of a wearable clinical thermometer. The temperature sensors are designed to be detachable from/reattachable into the thermometer main unit, and have an associated information-recording medium. The method calibrates the temperature sensor whenever a temperature sensor is substituted in, enabling the temperature sensor alone to be made disposable. The temperature-sensor calibrating method includes acquiring base resistance values having been sampled on a per-temperature-sensor basis inside a constant-temperature tank; computing for the temperature sensor, based on the difference between the base resistance values and resistance values derived, utilizing the B constant, from actual temperatures gauged with a standard temperature gauge inside the constant-temperature tank during the sampling, a value designating a calibration coefficient; recording in the information-recording medium the value designating a calibration coefficient; and causing a terminal to read in the value designating a calibration coefficient from the information-recording medium.
