Claim 8:
9. An arrangement for measuring an environment parameter at a rotor of a rotary machine, in particular a turbomachine, comprising:
a SAW device electrically coupled with an antenna and arranged to be located in a first zone of the rotor,
a parameter-sensitive impedance device arranged to be located in a second zone of the rotor remote from the first zone of the rotor,
a first cable electrically coupling the SAW device and the temperature-sensitive impedance device; and
a second cable, identical to the first cable, electrically coupling the SAW device at a first end and short-circuited with a matching impedance device at a second end.
