Patent ID: 7178385

Claim:
An apparatus for detecting the presence of at least one leak in a first region of a part under test and for localizing the location of the at least one leak, wherein a first side of the first region contains a tracer gas and is at a higher pressure than a second side of the first region such that the tracer gas will emanate through the at least one leak from the first side to the second side, the apparatus comprising: a plurality of sensors positioned proximate to the first region, wherein each of the plurality of sensors is a metal halide sensor, each sensor being configured to detect the presence of a tracer gas emanating from a leak and to provide a sensing signal; a controller connected to the plurality of sensors and configured to provide a leak detection signal in response to at least a first sensor of the plurality of sensors detecting the presence of the tracer gas, the leak detection signal including leak detection information representative of the location of the leak in the first region based on the sensing signals received from at least the first sensor and a second sensor of the plurality of sensors; and an indicator configured to provide a visual indication of the location of the leak, wherein the indicator includes a display configured to display a first representation of the part under-test and sensor icon positioned on the first representation, the sensor icon corresponding to a location of a first sensor which is proximate to the location of the leak.
