Measuring Device with Two-channel Sampling

Shaft encoder device according to or 9, in which averaging is performed by means of weighting, and the selection means or the signal processing means is designed to adjust the weights according to the operational conditions data obtained by the operational conditions determining means.

Shaft encoder device for sampling a shaft, comprising

• first detection means designed to obtain first data about an angle of rotation of the shaft in a first manner;
• second detection means designed to obtain second data about the angle of rotation of the shaft in a second manner that differs from the first manner;
• signal processing means designed to receive the first data from the first detection means and the second data from the second detection means and to determine a first angle of rotation of the shaft from the received first data, and a second angle of rotation of the shaft from the received second data.

Measuring device for the determination of the position and/or the angle of rotation of a body that carries out a translatory and/or a rotary motion, comprising

• first detection means designed to obtain first data about the position and/or the angle of rotation of the body by means of a first physical measuring method,
• second detection means designed to obtain second data about the position and/or the angle of rotation of the body by means of a second physical measuring method that differs from the first physical measuring method,
• signal processing means designed to receive the first data from the first detection means and the second data from the second detection means, and to determine the position and/or the angle of rotation of the body from the first and/or the second data.
