摘要：

Possible ways of reducing calibration complexity are considered for a non-contact passive torque and temperature sensor based on three one-port SAW resonators working at 433-437 MHz. A spread of sensor characteristics is investigated and it is shown that dynamic calibration curves differ considerably from the static ones not allowing accelerated temperature variation during calibration. A simplified procedure is suggested using correction of generic calibration parameters based on individual sensor calibration only in one or two temperature points.
