Title: Leak sensor
Inventor: TAKENOSHITA ETSURO
IPC: G01N21/17
Filed: 2000-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a leak sensor capable of accurately detecting leaks. SOLUTION: The leak sensor 10 applies a probing beam to an interface between a translucent portion made from translucent material and a leak detection area and detects leaks on the basis of changes in the quantity of the beam reflected from the interface. The probing beam 58 is incident on the interface at an incidence angle equal to or greater than a critical angle; if there is no leaking liquid clinging to the interface, the probing beam is totally reflected by the interface with a reflection angle equal to or greater than the critical angle because of a difference in refractive index between the translucent portion 24 and air in the detection area 22;  if there is leaking liquid clinging to the interface, the refractive index at the interface is decreased and at the interface a portion of the probing beam 58 leaks into the liquid in the detection area 22, so that the quantity of the beam totally reflected by the interface is smaller than if there is no liquid clinging to the interface. The translucent portion 24 is provided with indentations 70 opposing the detection area 22, so that the totally reflected beam is used in the detection of leaking liquid.
