Title:
FREEZING DETECTOR
Document Type and Number:
Japanese Patent JPS62298745
Kind Code:
A
Abstract:
An arrangement for the detection of icing on the surface of an object includes an optical conductor in which the radiation from a source strikes at least one plane of the conductor, which is located in the area of the surface to be tested and which is accessible from outside the object, and a detector which receive the radiation coming from this conductor plane and converts it into an electrical signal. An evaluation device compares the signal which a threshold value and, depending on the result of the comparison, generates an alarm signal.
