Electrical model for two coils vibrating wire transducers without mutual couplings

The vibrating wire transducer represents, basically, a damped oscillating resonant circuit tuned on the vibrating wire mechanical resonant frequency. Determining the equivalent electrical circuit for vibrating wire transducers without mutual couplings is a very important step because implementing PSPICE models for the behavior analysis cannot be made correctly with mutually coupled impedances. The electrical models have a major impact in choosing the excitation method to be used and establishing the best criteria that reveal the main transducer parameters as well. This paper is a follow up of our previous work presented in [3], in which we introduced and validated the electrical coupled model for two coils vibrating wire transducers.
