1. A diagnostic system for monitoring operating conditions of components of a turbine machine, comprising:
- a non-contact area sensor, positioned relative to the turbine machine in spaced relation to a component of the turbine machine, that detects an operating condition of the turbine component, and the non-contact sensor monitoring a defined region of the component determined by a field of view of the sensor, and generates data signals representing the operating condition;
at least one wireless point sensor mounted on the turbine component and positioned on the turbine component at predetermined coordinates relative to the component, wherein the point sensor monitors the same operating condition as the non-contact sensor and generates data or data signals representing the operating condition;
wherein the non-contact sensor detects the operating condition within a first estimated range of accuracy and the point sensor detects the operating condition within a second estimated range of accuracy that is higher than the first estimated accuracy range;
a data acquisition and processing controller linked in data communication with the non-contact sensor and the wireless point sensor, wherein the controller is configured to calibrate the non-contact sensor or data received from the non-contact sensor using the operating condition data from the wireless point sensor.

Abstract
A diagnostic system and method for monitoring operating conditions of turbine machine components (18, 19, 22, 23) that comprise one or more non-contact sensors (24, 31) that detect an operating condition of a turbine component (18, 19, 22, 23) over a defined region of the component. In addition, point sensors (50) are provided that detect and monitor the same operating condition within the defined region. Data generated from the point sensor (50) is used to calibrate the non-contact sensor (24, 31) and the data generated by the non-contact sensor (24, 31).
