<p>An output signal derived from a sensor 1 measuring the displacement, speed, or acceleration of a continuous casting mould is compared with an output signal derived from a sensor 2 measuring the displacement, speed, or acceleration of the part of a transmission mechanism adjacent an oscillating drive, in order to detect play in the transmission. The sensor output signals are amplified, filtered and integrated before entering a divider 9 for comparison. <IMAGE></p> |
