Assignee:
General Electric Company - Niskayuna NY
International Classification:
G01T 1/24
US Classification:
25037015
Abstract:
An interface assembly for a sensor array is provided. The interface assembly may be made up of an integrated circuit package thermally coupled to the sensor array. The interface assembly may include a temperature control system for controlling the temperature of the sensor array. The temperature control system includes a temperature sensor for sensing a temperature variation of each sensor of the sensor array from an initial temperature beyond a predetermined threshold. A temperature controller is coupled to each temperature sensor and receives an output signal from the temperature sensor upon the sensor temperature variation exceeding the predetermined threshold. A temperature correction device is coupled to each temperature controller and causes the sensor temperature variation to fall within the predetermined threshold upon receiving a control signal from the temperature controller.
