ABSTRACT:
A two wire transducer and associated circuit processes an output voltage of the transducer to produce a first signal proportional to the position of a non-contacting movable core and to produce a second signal proportional to the temperature of operation of the transducer. The associated circuit includes an excitation source or current driver which provides a fixed frequency sinusoidal constant current across the transducer coil; and first and second demodulator circuits respectively extract position and temperature signals from the voltage developed across the coil of the transducer device. Thus, both temperature and position information are provided by a single device over a single pair of leads.
