FISO’s optical Easythrough is designed to be installed on the transformer tank wall or any other sealed environment. Its simple and proven design will be mated with FISO’s TPT-32 temperature sensors.

Specially designed for FISO’s Nortech power transformer temperature monitoring system, the Easythrough offers long term reliability and excellent chemical resistance to oil, kerosene, etc. FISO’s Easythrough is manufactured using a glass to metal solder bonding technology which offers reliable performances compared to conventional techniques using epoxy bonding.

The Easythrough effi ciently conveys optical signals between the Nortech signal conditionners and TPT-32 temperature sensor for reliable measurements. The Easythrough is fully optical and has a low insertion loss, allowing better signal transfer from optical sensors embedded inside the transformer and the outside instrument.
