Resonator transducer system with temperature compensation

A resonator transducer system for determining force or other parameter and temperature comprising

• a single vibratory element which is responsive to an oscillatory electrical signal for resonating at frequencies f.sub.1 and f.sub.2, with the frequencies being selected from the group of frequencies consisting of the fundamental and overtone frequencies of the vibratory element, where the two frequencies vary with variation in force or other parameter applied to the vibratory element and with variation in temperature to which the vibratory element is exposed, with the magnitude of variation of frequency f.sub.1 due to the change in force or other parameter or the change in temperature being different from that for frequency f.sub.2,
• means for applying an oscillatory signal to the vibratory element to cause the vibratory element to resonate and for producing a vibratory signal having frequencies f.sub.1 and f.sub.2 which follow the selected frequencies of resonance f.sub.1 and f.sub.2 respectively of the vibratory element, and
• processing means responsive to the frequencies f.sub.1 and f.sub.2 of the vibratory signal for producing a first signal representing the force or other parameter applied to the vibratory element and a second signal representing the temperature to which the vibratory element is subjected.
