A device for measuring the grinding gap between two grinding discs in a disc refiner.

摘要

In a refiner with width of the gap (8) is indicated by a transmitter (10) located in one (4) of two counter-rotating refiner discs (4, 5). The indicating device operates according to the reluctance method, and electric effect is transferred contact-free to the transmitter (10) via one axle (2) through a transformer coupling (15, 17, 18, 20). The measurement signal from the transmitter (10) is transferred contact-free from a transmitting means (22, 23) on the axle (2) to a stationary receiver means (21, 24).
