3. Product Introduction (Anti-Template)
Electromagnetic flowmeters in hygienic and process applications depend on a reliable electronics cartridge to convert the sensor signal into a usable flow measurement. The D674A905U01 is the U-low HART cartridge designed for the ABB FET300 / HygienicMaster 300 family.
It houses the signal processing, HART communication, and output electronics that interface with the flowtube. Plants that standardized on the FET300 platform keep this cartridge available because a failed electronics module stops flow indication and totalization until a replacement is installed and reconfigured.

5. Field Application & Technical Pitfalls (The Engineer’s Guide)
This cartridge is used on HygienicMaster 300 and related FET300 magmeters in food & beverage, pharmaceutical, and general process lines where sanitary design and HART diagnostics are required. It converts the electrode signal into a 4–20 mA / HART output.
Three pitfalls appear during replacement:
Sensor and cartridge matching – the cartridge must match the specific flowtube size, lining, and electrode material; an incorrect pairing produces calibration errors or no measurement.
HART and configuration loss – replacing the cartridge often requires reloading the meter configuration, zero, and span values from the previous unit or from documentation.
Sealing and grounding – improper reassembly of the cartridge housing can compromise IP rating or introduce noise into the low-level electrode signal.
One plant replaced a cartridge and immediately saw unstable zero readings. The new unit was healthy, but the empty-pipe detection and zero calibration had not been re-entered; performing a proper zero adjustment restored stable measurement.
6. Quality Control (QC) SOP & Transparency
- Inbound Verification – OEM labeling, part number, and date codes are photographed and checked against the packing list; any signs of prior field use are noted.
- Live Rig Testing – cartridge is installed on a compatible FET300 sensor (or test fixture), powered, and verified for basic signal output and HART communication.
- Parameter Testing – output stability, HART response, and diagnostic functions are confirmed where possible.
- Final QA & Packaging – unit is sealed in an anti-static bag with desiccant, fitted with a QC-passed label showing test date and technician ID, then double-boxed for shipment.
7. Frequently Asked Questions (FAQ)
What is the D674A905U01 used for?
It is the electronics cartridge (transmitter module) for ABB / HygienicMaster 300 electromagnetic flowmeters, providing signal processing and HART communication.
Does it support HART?
Yes. This is the U-low HART version of the cartridge.
Is configuration retained when the cartridge is replaced?
Typically no. Meter-specific parameters (zero, span, density, etc.) usually need to be reloaded or re-entered after cartridge replacement.
What power does the cartridge require?
It is designed for standard 24 V supply used by the series. Confirm the exact rating on the unit label.
What warranty comes with a new-surplus unit?
Twelve months from shipment against defects in materials and workmanship when installed within the published ratings.
How do I confirm the cartridge is healthy after installation?
Apply power, verify the local display or 4–20 mA output responds to flow (or simulated signal), confirm HART communication if used, and perform a zero check with the pipe full and no flow.
