RTDs with Threaded Thermowell

Optional
Approvals
EX CertificationUKCA Certification

Complete RTD assemblies with threaded thermowells for direct process installation — precise temperature measurement with built-in sensor protection.

Thread­ed ther­mow­ells allow RTD assem­blies to be screwed direct­ly into pipework, ves­sels, or process con­nec­tions for a secure, leak-tight instal­la­tion. Avail­able with BSPP, BSPT, or NPT threads in sizes from ¼” to 1″, the ther­mow­ell pro­tects the sens­ing ele­ment while allow­ing removal and replace­ment with­out inter­rupt­ing the process. Heli­cal (straked) ther­mow­ell designs are also avail­able for high-veloc­i­ty appli­ca­tions where vor­tex-induced vibra­tion is a con­cern. Suit­able for tem­per­a­tures from ‑196°C to +650°C, with ATEX, IECEx, and UKEX approvals avail­able for haz­ardous area installations.

RTA101

RTD Sensor with Solid Drilled Threaded Thermowell

An RTD sen­sor sup­plied with a sol­id drilled thread­ed ther­mow­ell, pro­vid­ing robust pro­tec­tion for the sens­ing ele­ment in demand­ing process envi­ron­ments. Designed for direct instal­la­tion into pipework or ves­sels, this assem­bly is suit­able for high-pres­sure and high-tem­per­a­ture appli­ca­tions where dura­bil­i­ty and reli­a­bil­i­ty are essential.

RTA101H

RTD Sensor with Solid Drilled Helical Threaded Thermowell

An RTD sen­sor sup­plied with a heli­cal straked drilled thread­ed ther­mow­ell, engi­neered to sup­press vor­tex shed­ding and reduce flow-induced vibra­tion. The heli­cal geom­e­try low­ers dynam­ic stress­es on the sens­ing ele­ment while pro­vid­ing robust mechan­i­cal pro­tec­tion. Suit­able for high-pres­sure, high-tem­per­a­ture, and high-veloc­i­ty appli­ca­tions where dura­bil­i­ty and reli­a­bil­i­ty are essential.

RTD Sensor with Fabricated Threaded Thermowell

This RTD sen­sor assem­bly incor­po­rates a fab­ri­cat­ed thread­ed ther­mow­ell, offer­ing a cost-effec­tive solu­tion for many indus­tri­al process appli­ca­tions. It pro­vides reli­able sen­sor pro­tec­tion while allow­ing flex­i­bil­i­ty in mate­ri­als, dimen­sions, and process con­nec­tions to suit spe­cif­ic oper­at­ing requirements.
