CORROSION RATE SENSOR BASED ON ELECTROMAGNETICALLY INDUCED CURRENT

This Report summarizes the research study conducted on the design of corrosion rate
sensor based on electromagnetically induced current. This sensor will help in the
monitoring the corrosion rate in industries. This inspection system will result in the
improvement of safety, environment protection, equipment protection, smooth plant
operation and production rate, product quality, profit optimization, monitoring and
diagnosis. The design of sensor base on the electromagnetic field to measure
corrosion rate, where current is allowed to flow through the metal plate. The current
has its own magnetic field around metal plate and if a conducting loop is placed and
moved near the magnetic flux, electromagnetically induced current will flow in the
conducting loop. The magnitude of electromagnetically induced current should be
proportional to the thickness of the metal plate, and the electromagnetically induced
current should be lower if the loop is near a corroded region ofthe metal structure.
