CORROSION MONITORING SYSTEM

摘要

A corrosion sensor (20) for sensing corrosion includes a housing (28) and a device (36) for jointing the housing (28) to a wall of a pipeline (10) that receives a fluid (24). The sensor (20) also includes a rupture member (44) which extends across a portion of the housing (28) to define a seal chamber (48) in the housing (28). The rupture member (44), upon rupture, provides an opening to the sealed chamber (48). The rupture member (44) is formed of a material and thickness such that the rupture member (44) will fail from corrosion before the enclosure wall will fail from corrosion. The sensor also includes a sensory device (100) which is connected to the housing (28) at the sealed chamber (48) to signal a rupture condition.
