Abstract
A measurement system for determining a gap of a roll pair by scanning the position of the roll body ends on the side facing away from the roll gap. The system includes a lever bar arranged on a carrying structure and carrying a height-adjustable optical scanning device. A position element is arranged to rest on the roll barrel and is located in the optical beam path between a transmitter and a receiver of the scanning device and changes in the position of the position element can be detected by the scanning device. The transmitter, designed on the basis of a laser, and the receiver, designed as a photo receiver, are located in a common housing, into the interior of which gas can be introduced at an overpressure. The position element is attached in a vertically movable fashion via an articulated lever on the housing and consists of a glide plate resting on the roll barrel and a position measurement plate. The measurement plate is arranged vertically on the glide plate and extends in a freely movable fashion through a slot in the housing wall into the optical beam path between the transmitter and the receiver and at least partially covers it with a sharp measurement edge embodied on …
