Featuring connection heads, the Watlow AR style mineral insulated thermocouple is resistant to dust and
moisture, which ensures continuous long term reliability. This is possible because the covers keep the
connection to the extension wire clean.
The Watlow AR style mineral insulated thermocouple features connection heads that are designed to mate
to a conduit, allowing permanent installation. A variety of head styles are available, including plastic, cast
iron, aluminum and explosion proof.
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.
The XACTPAK protecting sheath and compacted insulation outperforms bare wire thermocouples in most
applications.
