Abstract
Apparatus for monitoring alignment of a transverse member conveyor. The member is attached transversely at opposite end portions to two parallel endless chains includes two position sensors affixed and located transversely adjacent to each chain and each other. One or more targets are attached to link(s) of each chain, and at predetermined distances from the member. The position sensors inductively or magnetically sense the relative position of the target(s) on each chain with respect to the respective position sensor adjacent the chain, and send a signal comparing the target and sensor proximity with respect to the target on each chain. This allows determination of whether the opposite end portions of the member attached to the respective chains are aligned transversely within predetermined tolerance limits. Another aspect is monitoring a single position on an endless chain. Another aspect monitors chain catenary.
