Device for determining surface moisture
First Claim
1. A device for determining surface moisture, which comprises a Dove reflection prism (1), a radiation source (2) of such a design that its beams (2a), which are aligned parallel, perpendicularly strike one of the two small surfaces (3) of the prism, a light trap (4) which traps the light beams (2c) emanating from the other small surface (5), and a photoelectric transducer (10) which is located in the angle formed by the two small surfaces and is arranged such that its measurement surface is located parallel and opposite to the hypotenuse surface of the prism, and which converts the light (2b) scattered by the surface which is to be measured.

Abstract
A device for determining surface moisture, especially of absorbent materials, comprises a Dove reflection prism, a radiation source of such a design that its beams, which are aligned parallel, perpendicularly strike one of the two small surfaces of the prism, a light trap which traps the light beams emanating from the other small surface, and a photoelectric transducer which is located in the angle formed by the two small surfaces and is arranged such that its measurement surface is located parallel and opposite to the hypotenuse surface of the prism.

2. A device for determining surface moisture, which comprises a cuboid block (11) having two opposite parallel sides, a flat bottom surface and a top surface parallel to the bottom surface, two prisms (12 and 12'"'"'), one attached to each of the two opposite sides of the cuboid block, a radiation source (2) of such a design that its beams (2a), which are aligned parallel, perpendicularly strike one of the two prisms, and a photoelectric transducer (10) which is located in the angle formed by the two prisms and is arranged such that its measurement surface is located parallel and opposite to the bottom surface of the cuboid block, and which converts the light (2b) scattered by the surface which is to be measured.
