Measurement value transducer, especially a linear displacement transducer for use in a blowout preventer for an oil or gas well, has a bit pattern generator whose signal is detected and evaluated to indicate component position

摘要

Measurement value transducer (1) for measuring at least one kinematic measurement value, especially for use in a device (2) for mineral oil and gas production. Said device has a first device part (3) that moves relative to a second fixed device part (4). As the moving part moves along a movement direction (5) a bit pattern is generated, from which position specific bit pattern groups can be sampled by a sampling unit (8).
