Watlow AF Style Mineral Insulated Thermocouple with Metal Transitions

Metal transitions are the distinguishing feature of the Watlow AF style mineral insulated thermocouples. The transition provides a durable, potted connection between the XACTPAK sheathed thermocouple material and the flexible SERV-RITE® insulated wire.

On the Watlow AF style mineral insulated thermocouples with metal transitions the transition is crimped to the sheath 0.040 in. and larger. Crimping is a quick, reliable method of attachment.

Watlow Mineral Insulated Thermocouples

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.
