Watlow AC style mineral insulated mini plug thermocouples are fast-responding, durable, and capable of handling higher temperatures than non-insulated thermocouples.
Watlow AC style mineral insulated mini plug 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 protects the Watlow AC style mineral insulated mini plug thermocouple from moisture, thermal shock, high temperatures, and high pressure to allow the T/C to outperform its bare wire counterparts in most applications.
The Watlow AC style mineral insulated mini plug thermocouple features mineral insulation for performance and mini plug or jack terminations that can be quickly connected or disconnected. Miniature connectors, available with thermocouple diameters up to 0.125 in. (3.0mm), can be used in locations where space is minimal. The miniature plug permits quick connection to portable instrumentation. Besides saving time, the Watlow AC style mineral insulated mini plug thermocouple offers the advantage of ease of use even by inexperienced personnel. In addition, color coding per ASTM E 230 specifications will help you easily determine the calibration.
On all the Watlow AC style mineral insulated mini plug thermocouples (except ASTM E 230 Type R and S), the pins and contacts are of the same alloy as the thermocouple, resulting in higher accuracy. This technique eliminates errors due to temperature gradients across the connector. Type R and S connectors have compensating alloys.
