Abstract
A tamper alarm circuit for detecting a tampered condition of a utility meter is disclosed. The tamper alarm circuit has a transducer coupled to an amplification circuit which is coupled to a detection circuit, the detection circuit generating an alarm condition when the detection circuit determines that a voltage signal generated by the transducer and amplified by the amplification circuit has reached a predetermined threshold.
