Aluminum / SST / polypropylene heads for various environments. R / T / P / L are 6-terminal aluminum heads (flat or extended cover, painted or unpainted). N is sensor-only with PTFE-insulated lead wires (lowest cost, no head).
Capsule (01) is the cheapest but only works with no-head N variant and no approvals. General-Purpose (11) is the workhorse. Spring-loaded (21) ensures positive thermowell contact. Bayonet (31) is quick-disconnect (1-21 in lengths).
A nipple coupling and C nipple union provide thermal isolation between the sensor head and the hot process surface. N (none) is for sensor-only / no-extension builds.
Length of the sensor sheath that enters the process or thermowell. Wide range available 1-48 in in 0.5-in increments. Most common presets shown; specify a custom length for anything else.
Rosemount is configurator-heavy and quote-only — Valley Instrument verifies option compatibility, lead time, and pricing before confirming your order.
Non-intrusive pipe-clamp temperature sensor — the key piece of Rosemount X-well Technology. Wraps around the outside of a pipe with a thermally-conductive clamp to measure internal process temperature without a thermowell or process penetration. Single-element 4-wire (P1) or dual-element 3-wire (P2) silver-tip RTD, -58 to 572 °F. Pairs factory-assembled with a Rosemount 3144S / 3144P / 648 transmitter and an X-well thermal-conductivity algorithm to back-calculate the internal process temperature. Wide pipe-size selection — DN15 through DN1500 / ½-60 inch — with clamp materials in 316 SST, 304 SST, Super Duplex, and Carbon Steel.
Built-to-Order custom RTD and thermocouple sensor — the flexibility platform of the Rosemount temperature line. Industrial, Cable, Surface, and Bearing sensor designs covering applications where the standardized 214C / 214C-TC / 68Q families don't fit: surface temperature on rotating equipment bearings, cable-style sensors with flying leads or MI sheath, special-purpose mounting (bayonet, screw-in cable, DIN plate). RTD types: thin-film PT100/PT1000 (best for vibration), wire-wound PT100/PT1000 (best for accuracy). TC types: E, J, K, N, T. Multiple sheath materials, diameters, and wire-configuration options (single/dual, 2/3/4-wire RTDs, grounded/ungrounded TCs). Most configurations require a Configuration Data Sheet (CDS) at quote — the encoded options below capture the major decision points; finer details get specified during the quote process.
Industry-standard temperature sensor — RTD (PT100) and thermocouple (J, K, T, N, E) variants for tough process environments. Standard outside diameter ¼-in (6 mm). Two element technologies: wire-wound (best for low-temperature accuracy, -148 to 842 °F) and thin-film (best for vibration/physical shock, high-temp up to 1112 °F). Multiple sensor mounting styles (Spring-loaded, Welded, Compact, with-indicator) for direct immersion or thermowell pairing. Single or dual 3-wire/4-wire element configurations for redundancy or 4-wire accuracy. Pairs natively with Rosemount 114C / Twisted Square thermowells and 248 / 248R / 644 / 3144P / 3144S / 648 transmitters.
Industry-standard thermocouple sensor — the TC sibling of the 214C RTD platform. Same standard ¼-in (6 mm) OD, same mounting styles (Spring-loaded, Welded, Compact, with-indicator), same connection-head options as the RTD variant. Five thermocouple types: E (highest output, non-magnetic), J (most common, iron/constantan, -40 to 1400 °F), K (high-temp, Chromel/Alumel, up to 2192 °F), N (highest thermoelectric stability vs E/J/K/T), T (low-temp, copper/constantan, down to -321 °F). IEC 60584 Class 1 or 2 tolerance, plus ASTM E230 Special and Standard Tolerances. Pairs with Rosemount 114C / Twisted Square thermowells and 248/644/3144P/3144S/648 transmitters.
