For Use With Thermowells Style AT

Detail Style AT thermocouple is an energy and process temperature sensor that features XACTPAK metal-sheathed mineral insulation, enhancing the sensor’s ability to “read” temperature by transferring heat quickly to the measuring junction.
  This thermocouple style is ideal for process petrochemical
and power applications where a sensor-thermowell assembly
is typically used. Thermowells protect the thermocouple and
allow replacement of the sensor without shutting down the
process, saving valuable downtime.
Features and Benefits Designed for use with thermowells, Style AT is ideal for process industry applications
  Compliance with specifications such as ASTM assures high quality sensor products
  Manufacturing capabilities include special tube cleaning processes, insulation baking to 1095˚C (2000˚F) and much more
  Connection heads come in four different styles
  Spring-loading option allows the thermocouple to maintain contact against the bottom of the thermowell, assuring rapid heat transfer to the sensor
Applications Petrochemical
  Refineries
  Power stations
  Blast furnaces
  Incinerators
