RTDs with Flanged Thermowell

Optional
Approvals
EX CertificationUKCA Certification

RTD assemblies paired with flanged thermowells for secure, leak-tight connections on pipelines and vessels operating under pressure.

Flanged ther­mow­ells pro­vide a bolt­ed, pres­sure-rat­ed con­nec­tion for RTD assem­blies on high-pres­sure pipework, ves­sels, and reac­tors where a thread­ed fit­ting isn’t suit­able. Avail­able with ANSI flange rat­ings from 150lb to 1500lb and PN16 to PN40 in sizes from 1″ to DN80, these assem­blies are well-suit­ed to demand­ing process and petro­chem­i­cal appli­ca­tions. Heli­cal (straked) ther­mow­ell designs are also avail­able for high-veloc­i­ty appli­ca­tions where vor­tex-induced vibra­tion is a con­cern. ATEX, IECEx, and UKEX approvals are avail­able, with all assem­blies man­u­fac­tured to your specification.

RTD Sensor with Solid Drilled Flanged Thermowell

An RTD sen­sor sup­plied with a sol­id drilled flanged ther­mow­ell, designed for secure instal­la­tion in high-pres­sure and high-tem­per­a­ture process appli­ca­tions. The flanged con­nec­tion pro­vides a robust mechan­i­cal seal, mak­ing this assem­bly suit­able for demand­ing indus­tri­al environments.

RFA101H

RTD Sensor with Solid Drilled Helical Flanged Thermowell

An RTD sen­sor sup­plied with a heli­cal straked drilled flanged 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.

RFA210

RTD Sensor with Solid Drilled Flanged Thermowell & Coating

This RTD sen­sor assem­bly fea­tures a sol­id drilled flanged ther­mow­ell with an option­al pro­tec­tive coat­ing. The coat­ing pro­vides addi­tion­al resis­tance to cor­ro­sion or aggres­sive process media, extend­ing ser­vice life in harsh oper­at­ing conditions.

RFA401

RTD Sensor with Solid Drilled Stepped Flanged Thermowell

An RTD sen­sor with a sol­id drilled stepped flanged ther­mow­ell, designed to improve ther­mal response while main­tain­ing mechan­i­cal strength. This design is com­mon­ly used where faster tem­per­a­ture mea­sure­ment is required with­out com­pro­mis­ing process integrity.

RFA501

RTD Sensor with Fabricated Flanged Thermowell

A cost-effec­tive RTD sen­sor assem­bly incor­po­rat­ing a fab­ri­cat­ed flanged ther­mow­ell. Suit­able for a wide range of indus­tri­al appli­ca­tions, it offers flex­i­bil­i­ty in design and mate­ri­als while pro­vid­ing reli­able pro­tec­tion for the sens­ing element.
