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

摘要

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.
