Abstract
A method includes receiving data characterizing an output of a sensor coupled to an industrial equipment. The output can include a sum of a first secondary coil and a voltage of a second secondary coil. The first secondary coil can be included in a first circuit and the second secondary coil can be included in second circuit configured within the sensor. The method can also include determining an integrity state of a circuit configured within the sensor. The integrity state can be determined based on the received data. The integrity state can identify a state of operation of the circuit configured within the sensor. The method can further include providing the integrity state. Related systems, techniques, and non-transitory computer readable mediums are also described.
