Claim 0:
1. A system for measuring temperature in a sterilization autoclave, comprising:
at least one temperature transducer positionable inside a sterilization chamber of the autoclave; and
at least one receiver positionable outside the sterilization chamber,
wherein the at least one receiver comprises:
a reception antenna, and
a receiving electronic circuit connected to the reception antenna and connectable with a process controller of the autoclave, wherein said receiving electronic circuit is configured to receive a digital temperature signal through the reception antenna, provide a control signal as a function of the digital temperature signal and transmit the control signal to the process controller,

wherein the at least one temperature transducer comprises:
a hermetically closable transducer housing,
temperature probes adapted to generate an analog temperature signal corresponding to a temperature to which the temperature probes are exposed, the temperature probes being movable with respect to the transducer housing and connected thereto through signal conductors for transmitting the analog temperature signal,
a transmission antenna connected to the transducer housing,
an electronic transduction circuit housed inside the transducer housing and connected to the signal conductors and to the transmission antenna, wherein the electronic transduction circuit is configured to convert the analog temperature signal into the digital temperature signal and transmit the digital temperature signal through the transmission antenna to the receiver, and
a primary battery to provide an autonomous electric power supply of the electronic transduction circuit, and

wherein the reception antenna of the receiver is configured to transmit signals at two or more different frequencies.
