Mineral Insulated Sensors
Watlow MI sensors
Watlow’s mineral insulated thermo-couples are fast-responding, durable, and capable of handling high temperatures. These 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.
Features
Easily handles temperatures up to 2200°F (1200°C)
Meets or exceeds initial calibration tolerances per ASTM E 230
Special mineral insulation protects thermocouple from moisture and thermal shock, and permits operation in high temperature, high pressure environments.
Small diameters—as little as 0.010 inch (0.25 mm) are an excellent choice when physical space or extremely fast response are critical.
Rigid quality control procedures assure high standards are met consistently in the manufacturing of XACTPAK.
Flexibility of the XACTPAK material allows you to form and bend the thermocouple, without risk of cracking, to meet your design requirements.
Outer Sheath protects the wires from oxidation and hostile environments.
In-house manufacturing of XACTPAK material assures single source reliability and permits faster turnaround times.
