Said second physical value represents a second detectable item of information in addition to the first physical value representing the data, independently of said first physical value .

To that end, a test valuator device (3) is used which, when an electrical checking signal is applied, generates a non-electrical physical value which is of the same type as the physical value to be measured by the sensor (2).

The physical value is determined by comparing the influence of changes in the at least two modes resulting from the influence of the physical value (such as ΔI).

Another physical magnitude appears at the exit according to the applied physical magnitude.

The physical variable (STR; P'; SP) is different from the beams (ST').

The sensor of the invention is used for measuring a physical value.

The invention relates to a device and a method for indicating a physical value.

A sensor process and device are described for determining a physical value by means of a laser whose emission properties can be influenced by the physical value.

If a physical amount is input, the system references the third database and presents information that is highly relevant to the input physical amount.

A converter (12) converts an input voltage to a first physical amount.

The device provides a means of indicating the physical value in the form of the temperature of a surface (2).

So the geology already is a bit more complicated than just a massive amount of granite.

Quantities are a product of a real number and a unit.

Physical quantities having magnitude and direction .
