Required Specifications
10 of 10 selectedThe 2240S is offered only in the Premium class. Tank-gauging applications demand ±0.05 °C accuracy.
Up to 16 RTD spot elements (Pt-100 or Cu-90). Code 00 = no temperature spots (water-level-only mode, requires aux input A).
The 2240S is fundamentally a tank-gauging device — Tankbus FOUNDATION Fieldbus is the only output.
All 2240S approvals are Intrinsic Safety — typical for Tankbus-powered field devices in tank-gauging service.
Custody-transfer codes (C/J/K) reserve one spot position for an external reference — reduces available element count by 1 (e.g. selecting 16 + C yields 15 usable spots). Requires pairing with a Rosemount 2410 Tank Hub + 5900S Radar Level Gauge with matching approval, plus a display (2410 integral, 2230 display, or TankMaster).
Standard polyurethane-covered aluminum IP66/67. Only option.
M = ready to mount directly to a Rosemount 565, 566, or 765 sensor head (the typical Tank-Gauging assembly). W/P = installation kit for separate sensor + transmitter installation.

Ships factory-assembled to the transmitter above. Configured part number generated separately.
565 Required Specifications
9 of 9 selectedThe tank-spanning length of the sensor. Metric range 2000-70000 mm (2-70 m) in 10 mm steps. US range 80-2700 in (≈6.7-225 ft) in 1 in steps. Custom length specified at quote.
ANSI raised-face flanges (A-L), EN flat-face flanges (1-7), or M33×1.5 threaded (code 0). All flanges in SST AISI 316.
1-16 spot elements distributed along the sensor length. Tank-gauging applications typically use 6-16 elements for full vertical profile.
IEC 60751 spec. Class 1/10 (code 2) requires four-wire sensor wiring.
Standard integrated installation with Rosemount 2240S transmitter is code 00. Specify a length code for remote-mount installations: 04-10 in meters, 13-33 in feet.

765 Required Specifications
10 of 10 selectedPDS: 765 metric range 2000-60000 mm (2-60 m, 10 mm steps) — note SHORTER than 565/566. US range 80-2300 in (1 in steps).
PDS: ANSI raised-face flanges (A-L), EN flat-face flanges (1-7), or M33×1.5 threaded (code 0). All flanges in SST AISI 316. Crude oil / petroleum tanks typically use 4-in or 6-in Class 150 RF.
PDS spot-element limits: wiring 4 → max 10 spots; wiring 3 → max 14 spots; wiring C → max 16 spots. (Water-level-only mode wiring=0 not exposed here — contact for quote.)
PDS: 01-16 spot elements distributed along the sensor length, with wiring-dependent maximums (see Sensor Wiring).
PDS: Class 1/10 (code 2) requires four-wire sensor wiring.
Standard integrated installation with Rosemount 2240S transmitter is code 00. Specify a length code for remote-mount installations: 04-10 in meters, 13-33 in feet.
PDS-real codes. Closed (C) for light products; open (H) for crude and heavy duty. Range is either 500 mm (19 in) or 1000 mm (39 in).

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).

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.

3144P Temperature Transmitter
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.
