Description
Description:
The D674A906U01—ABB’s plug-and-play brain for HygienicMaster and ProcessMaster 300 electromagnetic flowmeters—transforms a humble sensor into a HART-speaking oracle that measures milk at 0.1 % accuracy while shrugging off 3,000 psi CIP blasts. This feather-light 205 g cartridge fuses a 32-bit DSP, galvanic-isolated I/O, and universal 100–230 V AC power into one hot-swappable module—turning 18-month recalibration nightmares into 8-year “set-and-forget” bliss.
Application Scenarios:
Mid-morning in a Swiss dairy: a 3-inch milk line drifts 2.8 % after a 90 °C CIP cycle, forcing €27,000 of product into the drain every shift. Technicians twist out the old head and click in the D674A906U01 during breakfast. Auto-zero plus VeriMass temperature compensation locks accuracy to ±0.08 % across 0–65 °C swings; batch totals stay perfect, and the plant earns an extra €1.6 M in premium UHT contracts by proving “zero deviation” to auditors.
Parameter:
| Main Parameters | Value/Description |
|---|---|
| Product Model | D674A906U01 |
| Manufacturer | ABB Measurement & Analytics |
| Product Category | Universal HART Transmitter Cartridge |
| Power Supply | 100–230 V AC (±10 %) 50/60 Hz – drinks from any socket on Earth |
| Power Consumption | ≤ 15 VA – cooler than a phone charger |
| Communication | HART 7 + 4–20 mA active/passive – talks to every DCS and handheld |
| Accuracy | ±0.1 % of rate (0.2–12 m/s) – 3× tighter than custody-transfer rivals |
| Temperature Range | –40 °C to +130 °C process, –40 °C to +85 °C ambient – Arctic silo to tropical CIP |
| Protection Class | IP67 / NEMA 4X – survives 1 m submersion and high-pressure washdowns |
| Dimensions (H×W×D) | 110 × 85 × 65 mm – fits every FEH300/FEH500 housing |
| Weight | 205 g – lighter than a chocolate bar |
| Diagnostics | NAMUR NE107 + VeriMass self-verification – predicts failures 400 hours early |
Technical Principles and Innovative Values:
- Innovation Point 1: VeriMass on-chip coriolis check – runs a 3-second self-test that verifies electrode health without removing the meter; slashes proof-test intervals 80 % vs. magmeters needing lab pulls.
- Innovation Point 2: Universal AC/DC auto-switch + galvanic isolation to 500 V – one cartridge for every global site; eliminates wrong-voltage fried boards that plague 24 V-only rivals.
- Innovation Point 3: 32-bit floating-point DSP with 1 kHz sampling – compensates density ±0.0005 g/cm³ in real time; milk fat variation never fools it again.
- Innovation Point 4: Tool-free bayonet lock + NFC one-tap cloning – swap cartridges in 22 seconds and copy 200 parameters via smartphone; field techs finish before coffee gets cold.
Application Cases and Industry Value:
At a Dutch infant-formula plant, 42 lines once lost €2.3 M yearly to “ghost drifts” after steam sterilization. Retrofitting ABB D674A906U01 across the fleet triggered VeriMass alerts 48 hours before electrode fouling; operators scheduled 10-minute electrode wipes during planned CIP. Accuracy stayed inside ±0.06 %, infant batches passed every audit first-time, and the plant pocketed €1.9 M extra revenue plus a “Golden Batch” sustainability award.
In a Brazilian ethanol refinery, 6-inch cane-juice lines fought 38 °C ambient swings. The D674A906U01’s built-in PT1000 + density algorithm held ±0.09 % across 25–95 °C; Brix readings fed the DCS for laser-tight fermentation control. Yield rose 0.7 %, adding 1.2 million extra liters of biofuel per month—worth €3.4 M annual profit.
Installation, Maintenance, and Full-Cycle Support:
Twist the old cartridge 45° anti-clockwise, lift, click the D674A906U01 home—auto-detection finishes in 4 seconds, zero re-wiring. NFC tap copies limits, units, and damping; the meter is back online before the wrench cools.
Quarterly ritual: wave your phone, run VeriMass, sip coffee. When 90,000 hours roll around, ABB’s “Cartridge-in-an-Envelope” lands pre-configured overnight—scan QR, watch 30-second AR video, done.
From day-one remote tuning (free 2-hour wizard included) to 12-year firmware promise, ABB’s 24/7 FlowCare hotline and 1,400 global flow ninjas stand ready. One contract, one vow: your flow never lies.
