PCT No. PCT/SE94/00121 Sec. 371 Date Jul. 31, 1995 Sec. 102(e) Date Jul. 31, 1995 PCT Filed Feb. 15, 1994 PCT Pub. No. WO94/19663 PCT Pub. Date Sep. 1, 1994The invention relates to a method and to an arrangement for measuring length or angles, in which method use is made of a tape-shaped transmitter element (1) which is provided with markings and is designed to be pulled out of and pushed into a housing (6), easing or the like, the latter being provided with at least one sensor (4, 5) for detecting the markings on the transmitter element, and with an electronics unit (33) for converting signals from the sensor into length measurements or angle measurements. The sensor detects the markings on the transmitter element, which markings are in the form of embossings (2) in a repeated pattern of embossings, which form a micro-corrugated, ribbon-shaped zone (3) on the transmitter element, which micro-corrugated zone is moved past the sensor which registers and counts the number of elevations and/or depressions in the micro-corrugated zone, which elevations and/or depressions pass the sensor from a certain starting position to a certain measurement point, which is converted in the electronics unit to a measurement value of the length or angle in question. |
