1. A microwire temperature measurement system configured to determine a temperature of a microwire temperature sensor including at least first and second temperature range microwire elements, the microwire temperature measurement system comprising:
an antenna configured to be positioned near the microwire temperature sensor; and
a reader configured to transmit an instigation signal to the antenna so that the antenna generates an interrogation signal such that the microwire temperature sensor generates a response signal when the antenna is near the microwire temperature sensor, the instigation signal including a first maximum ramp current amplitude and a second maximum ramp current amplitude greater than the first maximum ramp amplitude so that the response signal includes a first re-magnetization pulse corresponding to the first temperature range microwire element and a second re-magnetization pulse corresponding to the second temperature range microwire element, the first and second re-magnetization pulses being non-overlapping in the time domain.
