Method for detecting position of band saw blade on band saw, involves providing free space for accommodating metallic element such that change in voltage induced into receiver coil is generated by moving metallic element in free space

The method involves detecting induced voltage in receiver coil (16) using measuring device (20). The signal of the measuring device is fed to evaluation device (22) so as to determine position, velocity or size of metallic element (1). The free space (25) is formed between transmitting coil (11) and...

Beschreibung
Zusammenfassung:	The method involves detecting induced voltage in receiver coil (16) using measuring device (20). The signal of the measuring device is fed to evaluation device (22) so as to determine position, velocity or size of metallic element (1). The free space (25) is formed between transmitting coil (11) and receiver coil. The free space is provided for accommodating metallic element such that the change in voltage induced into receiver coil is generated by moving metallic element in the free space. An independent claim is included for device for detecting position of plate or strip-shaped metallic element. Die Erfindung betrifft ein Verfahren zur Erfassung eines metallischen Elements (1), mit wenigstens einer mit einer Spannungsquelle (12) verbundenen Sendespule (11) und wenigstens einer mit der wenigstens einen Sendespule (11) zusammenwirkenden Empfängerspule (16), in die durch das Magnetfeld der wenigstens einen Sendespule (11) eine Spannung induziert wird, sowie mit einer Messeinrichtung (20) zur Erfassung der in der wenigstens einen Empfängerspule (16) induzierten Spannung, wobei das Signal der Messeinrichtung (20) einer Auswerteeinrichtung (22) zugeführt wird, die eine Position, Geschwindigkeit oder eine Größe des metallischen Elements (1) ermittelt.
