Abstract
A corrosion monitoring device includes a sensor assembly and a detector circuit. The sensor assembly includes at least one sensor portion disposed in an interior of a pipe in a fire sprinkler system for sensing corrosion of a wall of the pipe. The detector circuit transmits an electrical signal through the at least one sensor portion, monitors an electrical characteristic of the at least one sensor portion based on the electrical signal, compares at least one of the monitored electrical characteristic and a change in the electrical characteristic of the at least one sensor portion to at least one of a predetermined value and a previously monitored electrical characteristic, determines a corrosion status indicative of at least one of a corrosion level and a rate of corrosion of the pipe wall based on the comparison, and outputs an indication of the corrosion status.
