摘要： Systems and methods of detecting failures in an assembly that uses a variable differential transformer sensor. In one embodiment, a signal processor receives an excitation signal applied to the sensor, and detects a zero-crossing of the excitation signal. The signal processor receives an output signal of the variable differential transformer sensor in response to the excitation signal, and detects a zero-crossing of the output signal. The signal processor detects a fault in the assembly responsive to a determination that the zero-crossing of the output signal is separated from the zero-crossing of the excitation signal by more than the detection threshold.

摘要： Apparatus and methods of detecting failures in systems having a four-wire variable differential transformer sensor. In one embodiment, a method of detecting failures includes monitoring a source frequency of an Alternating Current (AC) voltage applied to an input of a four-wire variable differential transformer sensor, and monitoring an output frequency for an output of the sensor. The method further includes comparing the output frequency with the source frequency, and detecting a failure if the output frequency is different than the source frequency.
