• High Temperature EGT Thermocouple Sensor

High Temperature EGT Thermocouple Sensor

Model : 22J

The improving global emissions and efficiency standards petition

the need for monitoring exhaust temperature for after treatment

purposes. Recognizing this need, Therm-O-Disc is expanding the

temperature sensing offering to help the

automotive industry in meeting these emissions requirements.

Therm-O-Disc developed this sensor for high temperature exhaust

applications reaching up to 1000°C. Thermocouple sensors are

designed for long term durability needs. Integrated with a highly

configurable smart electronic module, this EGT sensor will exceed

industry performance, providing an

optimized solution.
