11 product families(11 total products)
Programmable head-mount temperature transmitter. PC-configurable for multiple sensor type inputs (2-, 3-, 4-wire RTDs and most common thermocouples) with cost-effective installation versus running sensor wires direct to the control system. DIN-B form factor mounts inside the sensor's connection head. Wide enclosure selection — aluminum, SST, polypropylene BUZ, sanitary DIN-A/DIN-B, and TZ-A/BK polyamide — for hygienic, hazardous, and harsh-environment process. Worldwide hazardous-area approvals (FM, CSA, ATEX, IECEx).
Tank-gauging multi-input temperature transmitter — purpose-built for custody-transfer-grade tank temperature measurement. Integrates up to 16 Pt-100 RTD spot elements (Cu-90 also supported) over -200 to 250 °C, plus optional Rosemount 765 water-level sensor input. ±0.05 °C transmitter accuracy (excluding sensor error). Premium performance class, FOUNDATION Fieldbus / Tankbus 2-wire bus-powered output. Custody-transfer type approvals available for PTB (Germany), NMIM (Malaysia), and GOST (Kazakhstan) — requires pairing with a Rosemount 2410 Tank Hub and 5900S Radar Level Gauge of matching approval. Polyurethane-covered aluminum IP66/67 enclosure. Hazardous-area: Intrinsic Safety only (FM/CSA/ATEX/IECEx/INMETRO/NEPSI/TIIS/EAC/KCs).
Basic, cost-effective HART head-mount temperature transmitter for temperature monitoring points. DIN-B form factor mounts directly inside the sensor's connection head, eliminating the need for extension wires or multiplexers. Single-sensor 4-20 mA HART output, ±0.15 °C digital accuracy, with worldwide hazardous-area approvals (FM, CSA, ATEX, IECEx, NEPSI, EAC). Aluminum or stainless-steel enclosure options; sanitary DIN-A/DIN-B variants for hygienic process. Pairs with any standard 2-, 3-, or 4-wire RTD or thermocouple sensor.
Compact DIN-rail-mount variant of the Rosemount 248 platform. HART/4-20 mA temperature transmitter engineered for common single-point measurement applications where space-efficient panel/cabinet mounting matters more than direct-in-sensor-head installation. 3-Point Calibration Certificate (Q4) and Custom Configuration of Software Parameters (C1) available. Intrinsic-Safety-only certifications — the 248R typically lives inside a customer-provided cabinet, so flameproof/XP variants aren't part of the line.
Emerson's flagship field-mount temperature transmitter. Dual-compartment housing isolates electronics from field wiring for serviceability without exposing the loop. HART 4-20 mA or FOUNDATION Fieldbus output, single or dual sensor input, ±0.10 °C digital accuracy, and advanced diagnostics (thermocouple degradation, min/max tracking, sensor drift alert). Pairs with the Rosemount 0085 Pipe Clamp Sensor for X-well non-intrusive surface temperature measurement.
Emerson's newest flagship field-mount temperature transmitter. Industry-leading 0.05 °C accuracy (Ultra performance class), 20-year stability, IEC 61508 safety certification, and Bluetooth configuration via ReadyConnect technology. Dual-compartment housing isolates electronics from field wiring. HART 4-20 mA output with full diagnostic coverage from sensor to control room. Pairs with the Rosemount 0085 Pipe Clamp Sensor for X-well non-intrusive surface temperature measurement, or with Rosemount 214C / 214A / 65 sensors and 114C / Twisted Square thermowells for traditional in-process measurement.
Versatile temperature transmitter — head-mount (DIN A), field-mount, or rail-mount form factors with single or dual sensor input. HART 4-20 mA (all variants), FOUNDATION Fieldbus or PROFIBUS PA (single-sensor head-mount only). The workhorse temperature transmitter for general process service: pairs factory-direct with any Rosemount sensor (214C RTD, 0185/186 thermocouples) and thermowell. LCD display + LOI option, NAMUR alarm levels, and Hot-Backup / sensor-drift diagnostics on dual-sensor variants.
Industry-standard wireless temperature transmitter — best-in-class wireless accuracy and stability for process monitoring. Dual-compartment housing isolates electronics from field wiring. WirelessHART IEC 62591 with user-configurable update rate, 2.4 GHz DSSS radio. SmartPower module (Lithium-thionyl chloride, 10-year life @ 1-minute update). Single-sensor input pairs with the Rosemount 214C / 214A / 65 sensors or with the 0085 Pipe Clamp Sensor for X-well non-intrusive surface measurement. All certifications are Intrinsic Safety — by design, the 648 is battery-powered and approved for IS service worldwide.
High-density multi-input temperature transmitter — up to 8 sensor inputs in a single device. Best-in-class solution for high point-count applications: reactor temperature profiling, distillation columns, hotbox monitoring, tank stratification. FOUNDATION Fieldbus output only (3 AI + MAI + ISEL function blocks + Backup Link Active Scheduler). Accepts RTD, thermocouple, mV, and Ω inputs; with the S002 option, also accepts 4-20 mA inputs (mix-and-match sensor types per channel). Wide hazardous-area cert matrix — many regional approvals require pairing with a Rosemount enclosure / junction box.
Wireless surface / ambient temperature monitor — part of Emerson's Synchros IIoT platform for asset and condition monitoring. WirelessHART (IEC 62591) protocol, integrates with existing or new WirelessHART networks via a 1410S Gateway. Designed for asset-level trend monitoring (heat exchanger fouling detection, heat trace verification, reciprocating compressor valve health, distribution line monitoring). User-orderable with battery, integral thermocouple sensor, and mounting accessories — all in one model number. Mount options: bracket, pipe clamp (magnetic mount coming). Designed for hazardous-area service. Connects to Plantweb Insight Asset View for real-time alerts, trend charts, and asset health scoring.
