Abstract: A pump monitoring system for use in wellbore operations can determine whether an indication of a failure is due to an actual pump issue or a failed sensor. The pump monitoring system includes a sensor on a fluid end of a pump to measure properties associated with the pump and a vibration detector. A computing device executes instructions to receive the sensor signal and the vibration signal and identify an irregularity in the sensor signal. The processor then determines whether an operational signal component is present in the vibration signal, and displays an indication that the sensor has failed when the operational signal component is not present in the vibration signal. If the operational signal component is present in the vibration signal, the irregularity is likely caused by a pump problem such as a failed valve.
