Abstract
A novel fail-safe temperature monitoring system that can distinguish excessive chemical adsorbent temperature from temperature sensing component failure is provided. This system prevents the gas purifier from shutting down as a result of temperature sensing component failure, and thereby prevents a false shutdown of a high-purity gas production plant.
