Abstract
A system includes a rotor, a rotor antenna attached to the rotor, a strain detection device attached to the rotor, a programmable gain amplifier attached to the rotor, and a control module attached to the rotor. The strain detection device is configured to generate signals that indicate an amount of strain in the rotor. The programmable gain amplifier is configured to amplify the signals generated by the strain detection device by a gain value. The gain value is programmable. The control module is configured to program the gain value of the programmable gain amplifier and transmit, via the rotor antenna, digital data that is derived from the amplified signals.
