Watlow Style AC Connector MI Thermocouple
Mineral Insulated - Single Element - Plug or Jack Termination

The Watlow Style AC Mineral Insulated Thermocouple temperature sensor "connector" style come with a male plug or female jack connector directly attached to the sheath. Because it is constructed with XACTPAK mineral insulation, the thermocouple is protected from moisture, thermal shock, high temperatures and high pressure.

Achieving specified temperature levels is critical to industrial processes. It's imperative that temperature sensors are designed and manufactured to exacting specifications for accuracy and reliability. Watlow is committed to providing you with the most accurate, high-integrity temperature measurement products possible. Watlow offers the greatest breadth of contact temperature measurement sensors and related components. Whatever your temperature sensing needs, Watlow can provide the optimum configuration, with the accuracy you require.

Performance Capabilities:

  • Watlow MI thermocouples easily handle temperatures up to 1200°C (2200°F).
  • They meet or exceed initial calibration tolerances per ASTM E 230.
  • Diameters as small as 0.010 in (0.25mm)
  • Flexiblity of the XACTPAK material allows you to bend the thermocouple without risk of cracking
