Diodes GaAlAs Diodes Platinum RTDs Rhodium-Iron RTDs Cernox RTDs Cernox High Temp. This thermal conditioning step is performed at the factory prior to testing and calibration of the sensors. Extreme usage at high temperatures can induce shifting in a sensor calibration. The shifty and rate of shift are dependent upon the temperature and time at temperature.
Optimum performance is achieved by using the sensor in the hermetically sealed SD package.
For applications requiring a smaller package, a bare chip can be provided without or with gold leads, but best performance will be obtained when high temperature use is limited to a vaccum or inert gas enviornment. In each case, the shift is plotted realtive to the previous calibration, i.e. the zero deviation line in the previous calibration in each case. MEasurements below 1 K should be performed with an AC resistance bridge. Chip mounted on sapphire base with alumina body and lid. Gold-tin solder as hermatic lid seal.
