Title: Leak sensor
Inventor: MIZUNO TAKESHI
IPC: G01M3/38
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a leak sensor capable of detecting leaks by detecting a case where the leak sensor is not properly installed. SOLUTION: If the leak sensor is properly mounted and there are no leaks, light from a light projecting portion 50 is reflected by a detecting surface 15 toward a light receiving portion 51 and a portion of the light from the light projecting portion 50 is transmitted through the detecting surface 15 and is reflected by a surface to be immersed and is again transmitted through the detecting surface 15 and received by the light receiving portion 51. If the leak sensor is not properly mounted, a portion of the light from the light projecting portion 50, even if transmitted through the detecting surface 15, will not be reflected by the surface to be immersed and return to the light receiving portion 51. Hence, there is a difference in strength of light received by the light receiving portion 51 between when the leak sensor is properly mounted and when it is not.  By comparing a second reference level based on the difference to a received light signal outputted by the light receiving portion 51, any failure of the leak sensor can be detected.
