148 Temperature Transmitter
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).

2240S Multi-Input Temperature Transmitter
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).

248 Head Mount Temperature Transmitter
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.

248R Rail Mount Temperature Transmitter
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.
