Devices and methods for sensor data analysis of transient errors

A sensor analysis system for monitoring operation of a turbine engine of a power plant, the sensor analysis system comprising:

• a turbine control system configured to monitor a plurality of sensors associated with the turbine engine;
• a sensor device configured to monitor an aspect of operation of the turbine engine and transmit a first analog signal as an output signal;
• and
• a sensor analysis device coupled to the sensor device, the sensor analysis device configured to:
• receive the first analog signal from the sensor device;
• sample the first analog signal at a first rate defined by a device sampling period, the first rate comprising a first duration between samples;
• determine a second rate comprising a second duration between samples that is shorter than the first duration between samples captured at the first rate;
• sample the first analog signal at the first rate and the second rate;
• detect one or more samples from the second rate which includes a transient signal above or below a threshold value;
• and
• wherein the sensor analysis device is further configured to transmit a second analog signal via an analog output port;
• and
• wherein the second analog signal includes a first portion representing the first analog signal.
