614 Cryogenic Spot Temperature Sensor
SKU: 614
Single-spot cryogenic temperature sensor for LNG / cryogenic tank skin temperature, stratification detection, and Level/Temperature/Density (LTD) measurement. Designed to mount on the outside of cryogenic process equipment to measure skin or wall temperature without process penetration. Class A Pt-100 RTD, single or dual element, 4-wire or 3-wire configurations. Each Rosemount 2240S Multi-Input Temperature Transmitter supports up to 16 Rosemount 614 sensors — the standard architecture for monitoring multiple stratification points or skin-temperature locations across one large cryogenic tank.

Single-spot intrinsically-safe cryogenic temperature sensor (gas atmospheres Cat. 1 Zone 0) for full-containment cryogenic and refrigerated tanks. Spot elements wired through a mineral-insulated flexible steel cable up to 300 m (980 ft) — allows temperature measurement inside a full-containment tank during cool-down, and leak detection in the tank's insulation space. Single or dual Pt-100 element, 4-wire or 3-wire, Class A or Class B accuracy (per IEC 60751). Integrated to the Rosemount 2240S Multi-Input Temperature Transmitter via a conical connection or junction box — each 2240S supports up to 16 Rosemount 614 sensors. The 614 Flange (model 614-FLNG) is a separately-ordered companion accessory for multi-hole tank installations.
Required Specifications
8 of 8 selectedPDS Mxxxxxx — metric mm range 002000-300000 (10 mm steps, up to 300 m / 984 ft). Exxxxxx — US in range 000080-011810 (1 in steps). Custom length specified at quote.
PDS IEC 60751 accuracy classes. Class A is the cryogenic-targeted spec (±0.15 + 0.002·|t| °C, -170/+95 °C). Both classes work with either 3-wire or 4-wire — accuracy class itself does NOT impose a wiring constraint (PDS-confirmed).
PDS: 3 lead-out types. Type 1 = wired (cone bought separately). Type 2 = cable for junction box. Type 3 = wired with sliding fitting for junction box.
PDS: 00 = standard 560 mm (22 in.) — requires lead-out type 1 or 3. XX = non-standard 1-20 m (3-66 ft) — requires lead-out type 2 only.
PDS: code 1 (¼-in NPT) requires lead-out type 3 OR (lead-out type 1 with single-element). Code 3 (½-in NPT) has no restriction. When using flange fitting 1 with lead-out 1, the sensor must have a single element (numberOfElements=S).
PDS X4/X9 require sensor-wiring=4 AND Certificate Q4.
PDS: Q4 calibration certificate requires Sensor Calibration X4 or X9, AND sensor-wiring=4.

0085 Pipe Clamp Temperature Sensor
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.
214A Temperature Sensor (Built-to-Order)
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.
214C Temperature Sensor
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.
214C Thermocouple Temperature Sensor
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.
