Investigating the self-heating test for a temperature sensor using a ternary identification pattern

The dynamic properties of temperature sensors play an essential role in the performance of measurement and control systems. Identification patterns may be used in the on-line, in-situ monitoring of temperature sensors. In this paper the self-heating test for a temperature sensor using a ternary multifrequency identification pattern (MIP) is investigated. The dynamic behaviour can be monitored using the MIP, where the ternary signal MIP area, as a simple time domain aid, is examined at the output in terms of the dominant sensor time constant.
