The Watlow AT style mineral insulated thermocouple for use with thermowells is an energy and process temperature sensor that features XACTPAK metal-sheathed mineral insulation, enhancing the sensor's ability to "read" temperature by transferring heat quickly to the measuring junction.

The Watlow AT style mineral insulated thermocouple is ideal for process petrochemical and power applications where a sensor-thermowell assembly is typically used. Thermowells protect the thermocouple and allow replacement of the sensor without shutting down the process, saving valuable downtime.

Watlow mineral insulated thermocouples are fast-responding, durable and capable of handling higher temperatures.

Watlow mineral insulated thermocouples are manufactured with XACTPAK®, Watlow's trademark for metal-sheathed, mineral insulated (MI) thermocouple material. XACTPAK responds fast because the protective metal outer sheath allows the use of smaller diameter thermocouple conductors. The rock hard compacted MgO insulation further enhances the sensor's ability to "read" temperature by transferring heat quickly to the measuring junction.

Watlow mineral insulated thermocouples' XACTPAK protecting sheath and compacted insulation outperforms bare wire thermocouples in most applications.

Applications for Watlow AT Style Mineral Insulated Thermocouple for Use with Thermowells include heat treating, furnaces/kilns, turbines, bearing temperature, power stations, steam generators, diesel engines, nuclear reactors, atomic research, jet engines and test cells, rocket engines, semiconductor manufacturing, refineries/oil processing, catalytic reformers, and food processing.
