Excitation circuitry for variable reluctance transducer |
摘要 |
Improved excitation circuitry for a variable reluctance transducer is disclosed which includes a transformer having a primary winding and a secondary winding. Power circuitry coupled to the primary winding induces an AC excitation signal in the secondary winding which is coupled to the transducer. An error detection circuit compares a reference signal with the excitation signal and feeds back an error signal to the power circuitry to compensate for any differences therebetween. In such manner, a constant excitation signal is maintained for the transducer.
