CONVEYOR BELT RIP DETECTION SYSTEM WITH MICROWIRE SENSOR

摘要

The present invention relates to conveyor belts having rip detection systemswhichutilize microcoil sensor wires which offer improved durability as compared toconventionalmicrocoil sensor wires. This higher degree of durability increases the servicelife of the ripdetection system and allows for the conveyor belt to be used reliably over anextended timeperiod without the need to replace damaged microcoil sensor wires within therip detectionsystem of the conveyor belt. The present invention more specifically disclosesa conveyorbelt comprising (1) an elastomeric body having a load carrying surface and aparallel pulleyengaging surface; (2) a reinforcement ply disposed within the elastomericbody; and (3) a ripdetection sensor in the form of a microcoil sensor wire which is configured inan endlessloop, wherein the microcoil sensor wire is comprised of an elastomeric corehaving anelectrically conductive wire spirally wrapped around the elastomeric core.
