CONDENSATE DETECTOR AND METHOD FOR DETECTING CONDENSATE ON A SURFACE

摘要

A condensate detector capable of detecting the condensate eventually present on a surface to be monitored (SM) comprises: - emission means (1, 2) for emitting a first light beam onto a surface to be monitored (SM) and a second light beam onto a calibration surface (ST); - receiving means (3, 4) for supplying a first output signal (SEI) depending on the lighting radiation reflected from the surface to be monitored (SM) as a function of the condensate present onto the same, and a second output signal (SE2) depending on lighting radiation reflected from the calibration surface (ST); and - condensate control means (5) capable of maintaining the condensate present onto the calibration surface (ST) at a certain predetermined level. The invention also concerns a method for detecting the condensate eventually present onto a surface to be monitored (SM).
