Temperature Sensors

Sheathed Thermocouple & RTD

Sheathed temperature probes with insulated, grounded, exposed or separately insulated junction arrangements.

A sheathed temperature probe family for process equipment. Thermocouple and Pt100 assemblies can be configured with different junction and mounting arrangements. Junction choice changes electrical isolation, response and mechanical exposure.

Configuration & Documentation

These are product families. Final specifications, ordering code, availability and lead time are confirmed in the quotation.

  • Diameter values retain the catalog’s Ø notation. Confirm units, tolerances, insertion length and the final dimensional drawing before ordering.
  • Accuracy class is a catalog designation. Confirm the applicable standard, temperature interval and delivered tolerance in the quotation.
  • Model patterns are incomplete catalog references, not orderable part numbers. Confirm the element code, conductor arrangement and full ordering code.
  • Junction options below follow the thermocouple catalog. RTD junction and wiring applicability requires separate confirmation.
  • Pressure capability is not established for a complete assembly; provide the working pressure for engineering review.
Junction Options

Insulated junction (code 1)

Single / dual element diameterØ1.0–Ø8.0 / Ø1.0–Ø8.0
Selection characteristicElectrical isolation; slower response than a grounded junction

Grounded junction (code 2)

Single / dual element diameterØ0.25–Ø8.0 / Ø3.0–Ø8.0
Selection characteristicFaster thermal response; review susceptibility to electrical interference

Exposed junction (code 3)

Single / dual element diameterØ0.5–Ø8.0 / Ø3.0–Ø8.0
Selection characteristicFast response for applications such as exhaust gas measurement; lower mechanical protection

Separately insulated junction (code 4)

Dual element diameterØ0.5–Ø8.0
Selection characteristicSeparate insulation between two sensing elements; other characteristics follow the insulated construction
