System for monitoring the temperature of a rotating devices
First Claim
Patent Images
1. An improved system for monitoring the temperature of a rotating device comprising:
- a sensing means responsive to temperature stimuli of a rotating device thereby producing a signal;
an antenna means responsive to said signal of said sensing means coupled to a receiver means;
an amplification means coupled to said receiver means;
a first splitting means coupled to said amplification means for splitting said signal from said amplification means into a first amplified signal and a second amplified signal;
a phase lock loop circuit coupled to said first amplified signal;
a second splitting means coupled to said phase lock loop circuit outputting a valid frequency signal and said first amplified signal;
an amplitude modulation discriminator means coupled to said second amplified signal for validating an amplitude of said second amplified signal thereby producing a valid amplitude signal;
a comparing device coupled to both said valid frequency signal and said valid amplitude signal for comparison of said valid frequency signal and said valid amplitude signal whereby said comparing device produces a control line signal;
a counter logic circuit receiving said control line signal, said first amplified signal of said second splitting means, and a time based signal whereby said control line signal, said first amplified signal of said second splitting means, and said time based signal are synchronized;
said counter logic circuit producing a synchronous signal; and
a microprocessor coupled to said synchronous signal for calculating the temperature of said rotating device based on said synchronous signal.
