Sentinel is designed for large power transformers.

Designed for large power transformers, Sentinel from Nortech Fibronic Inc. monitors winding temperatures, preventing overheating of windings and keeping the transformer in top condition. It provides direct, accurate measurements of winding temperatures using dielectric probes attached directly to the hottest spots on the windings. Automated monitoring of hot spot temperatures is key to optimized loading while protecting transformers.
