SYSTEMS AND METHODS FOR LEAK TESTING A COMPONENT

Abstract:

A system for leak testing a component of an industrial machine. The system can include a supply, a first temperature sensor, a second temperature sensor, a temperature change unit and a controller. The supply can be configured to provide a gas to an interior of the component. The first temperature sensor can be configured to sense a temperature of the component. The second temperature sensor can be configured to sense a temperature of the gas of the supply. The controller can be configured to electronically communicate with the first temperature sensor and the second temperature sensor and can be configured to control the temperature change unit based upon the sensed temperature of the component and the sensed temperature of the gas of the supply to heat or cool the gas be substantially the same as the temperature of the component.
