The Watlow AT style mineral insulated thermocouple with thermowells feature high-quality Watlow sensors with 316 SS straight or tapered thermowells, nipple-union-nipple, 0.250 inch diameter spring loaded element, small aluminum connection heads, and ungrounded junction.
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.
