AKM345 GEN3 OTIWTI™

Oil- and windingtemperature indicator for power transformers

The AKM345 GEN3 OTIWTITM is the future of oil and winding temperature indication for transformers of all classes from the industry leader. The AKM345 GEN3 utilizes the same great bellows technology as previous generations with new features to support the digitization of transformers and standard options to meet all specification requirements. The new and improved design makes for an even more reliable and robust product with IP66 ingress protection and C5-High corrosion protection as a standard. The bellows technology allows for integrated winding temperature simulation and the ability to drive up to 6 adjustable switches and various remote outputs for monitoring applications.
