Abstract
A monitoring device for a handrail of a passenger conveyor includes a plurality of electrical conductors extending through the handrail, a device for inducing a current within the conductors, and a device for monitoring the induced current. In a particular embodiment, tension carriers within the handrail are electrically spliced together to form the electrical conductors. The level of current detected within the handrail is compared to an acceptable range and, if the monitored level is not acceptable, the passage conveyor is stopped.
