Drift compensation systems and methods are presented for compensating the drift of a sensor within a manufacturing lot. The system comprises a sensor test sample manufactured from a lot of material having substantially similar chemical or metallurgical properties, a drift characterization tester, wherein the test sample is exposed to a predetermined thermal environment. Measurements of the test sample output are analyzed to provide a drift function describing the relationship between time and temperature from the thermal exposure measurements of the test sample in the drift characterization tester. Parameters associated with the drift function and the sensor test sample are stored in a memory storage component associated with a second sensor. The second sensor is manufactured from the same lot of material as the sensor test sample.

A thermal device system including a device for measuring a temperature within a user environment and providing a device output signal indicative of the device measured temperature. The system also includes a thermal transfer indicia associated with the device. The thermal indicia provide thermal transfer parameters for compensating the device measured temperature as a function of the thermal transfer between the device and the user environment. The thermal transfer parameters are associated with predetermined thermal transfer information for characterizing a transfer of thermal energy between the device and the user environment. Also a method of compensating a temperature measurement of a thermal device in a user environment as a function of a thermal transfer of the thermal device in a temperature measurement system.

Certain exemplary embodiments can provide a system, which can comprise a thermocouple input module. The thermocouple input module can be adapted to determine one or more calibration factors. The thermocouple input module can be adapted to store the calibration factors. The thermocouple input module can be adapted to apply the calibration factors to an incoming thermocouple voltage value to obtain an adjusted thermocouple voltage value.

57 In a calibration warning device for a thermocouple, the thermocouple is connected to input terminals (10) of an operational amplifier (12) provided with negative feedback. The output is applied to the base of a transistor (14) controlling the current through a mercury coulometer (18). When the coulometer indicator reaches full-scale deflection the thermocouple is due to be recalibrated. The invention depends on the fact that the drift curve of a thermocouple can be matched to a sufficiently high accuracy by a suitable choice of transistor characteristic and amplifier gain, as is explained in the specification.
