DEVICE FOR DETERMINING THE ROTATIONAL SPEED OF A ROTATING MACHINE PART

Abstract

The invention relates to a device (1)for determining a rotational speed machine part (5)which comprises at least one signal input (13)to which the output signal (11)of a rotational speed sensor (10)can be supplied an arithmatic unit (20) which can be used to calculated ,on the basis of the output signal(11)of the rotational speed sensor(10)at least the rotational speed of the rotating machine part (5)and at least two signal inputs (25) for outputting the rotational speed calculated by the arithmatic unit(20).Any actual speed can be output by means of a second (252)of the at least two signal outputs (25)whose values are comprised by a predetermined rotational speed range which is a proper subset of an actual rotational speed operating range of the rotating machine part(5) the second signal input(252)allows outputting rotational speed values with a greater exactness if they are contained in the predetermined rotational speed change,especially in the range around the nominal rational speed
