Loop break detection and repair

摘要

An inductive loop break detector has two connectors to provide connections between a detector and two inductive loop wires. Signal LED indicators 312, 314 show whether a signal is present on each wire and phase LED indicator 310 shows whether the signals are in phase or out of phase, on the basis of microprocessor analysis. Also described is a Wire repair connector with ahousing402 having a bore for end sections of broken wire, and at least one aperture 406 for a fastener 408 to secure the ends of broken wire.
