A6312/06 | Emerson Speed Key Module

The two−channel rotational speed monitor A6312 is a module of the A6000 machine monitoringsystem. The micro−processor controlled monitor is used in conjunction with two eddy currentmeasuring chains or hall−effect sensors (e.g. PR 9376) and in combination with triggeringwheels to measure and conditioning of shaft speeds and rotational reference marks(key−pulses).Both channels may be used separately used to measure:• 2 speeds from 2 shafts• 2 key−pulses from 2 shafts each with a triggermark (with phase relation)Both channels may also be used in combination with each other:• to detect the direction of rotation of one shaft• to detect a difference between two shaft speeds
