550 Series Thermocouple and Resistance Thermometer assemblies with A Butt weld design tapered well. Flameproof or weatherproof execution in 316SS or Aluminum. Safe design as per ASME PTC 19.3 Available with "in head" 2-wire Temperature Transmitter.

Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and drilled bar stock weld-in thermowell would form a typical complete assembly ready for use in the application designed for. The design of the complete assembly depends on various process parameters, such as, temperature, dynamic pressure, flow velocity, abrasive nature of process fluid, intricate nature of installation and insertion lengths required.

High Velocity collar can be provided to reduce the suspended length of Thermowell and to meet ASME PTC19.3 requirement. Thermowells are available in standard AISI 300 series stainless steels as well as, in exotic materials such as Incoloy 800, Inconel 600, Monel 400.

The Thermowell illustrated here is a butt welding to a weldolet and well dimensions given are suitable for weldolet size of 1.5" and 2" and schedule 40 to schedule XXS.

The standard execution is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT and Thermocouples with ungrounded junction unless specified otherwise.
