Thermocouples with Weld-In Thermowell

Optional
Approvals
EX CertificationUKCA Certification

Thermocouple assemblies with weld-in thermowells delivering maximum mechanical strength for high-pressure or high-velocity process applications.

Weld-in ther­mow­ells are per­ma­nent­ly attached to the pipe or ves­sel wall, pro­vid­ing a per­ma­nent process con­nec­tion. Suit­abil­i­ty for high pres­sure, flow veloc­i­ty or vibra­tion depends on the com­plete design, weld­ing, inspec­tion and oper­at­ing con­di­tions. Avail­able in Type E, J, K, N, and T with probe mate­ri­als includ­ing 310 stain­less steel, 316 stain­less steel, and Inconel® Alloy 600, they are well-suit­ed to oil & gas, pow­er gen­er­a­tion, and chem­i­cal pro­cess­ing appli­ca­tions. ATEX, IECEx, and UKEX approvals are avail­able, with all assem­blies man­u­fac­tured to your specification.

TWA501

Thermocouple Sensor with Fabricated Weld In Thermowell

This ther­mo­cou­ple sen­sor assem­bly fea­tures a fab­ri­cat­ed weld-in ther­mow­ell, offer­ing a prac­ti­cal and eco­nom­i­cal solu­tion for many indus­tri­al process­es. It pro­vides reli­able sen­sor pro­tec­tion while allow­ing flex­i­bil­i­ty in mate­ri­als and construction.
