FOR IMMEDIATE RELEASE No. 3299
TOKYO, September 4, 2019 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed what is believed to be the world's first* compact metal corrosion sensor small enough to be mounted on printed circuit boards. The new sensor utilizes metal corrosion monitoring technology developed by Mitsubishi Electric that detects the degree of corrosion of metal components caused by corrosive gases such as sulfur compounds in the atmosphere. The deployment of multiple sensors with different levels of corrosion resistance allows the degree of corrosion to be detected in stages, helping to prevent equipment failure. Mitsubishi Electric plans to deploy the new technology across its own industrial equipment portfolio.
Example deployment of new sensor
When metals are exposed to corrosive gases in the atmosphere, corrosion progresses from the surface to the inside and turns into rust. Since the electrical resistance of rust is tens of thousands of times higher than that of metal, the progress of any corrosion can be gauged by measuring the increase in electrical resistance.
|Configuration of corrosion sensor
|1.6mm × 0.8mm ─ the size does not vary regardless of the material or thickness of the metal film or the resistance level of the resistor
