Title: Leak detector
Inventor: OKAMOTO HIDEKI
IPC: G01M3/22
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To enable utilization of gas that is inexpensive and familiar as a probe gas and to decrease the running cost at the same time by providing a gaseous thermal conduction-type gas sensor at a detecting part of the probe gas. SOLUTION: A gaseous thermal conduction-type gas sensor 7 is arranged halfway in an exhaust system of a leak detector 1. When there is a leakage in a body to be detected, the probe gas that is compressed and sealed into the body to be detected, is introduced into the pipe in the leak detector 1 and guided into the sensor 7. A sensor 8, which constitutes one side of the bridge circuit of the sensor 7 and comprises a platinum wire coil or the like, is arranged in the exhaust path. When there is leakage in the body to be detected, the probe gas components are mixed into the exhaust gas, the composition of the exhaust gas changes and the thermal conductivity also changes. Therefore, the temperature of the sensor 8 also changes, and that temperature change is regarded as the change in resistance value, and an electric signal is detected from the bridge circuit.  Therefore, the mixing amount (leak amount from the body to be detected) of the probe gas can be quantitatively detected.
