Technical Specifications

Note: Electrical parameters such as supply voltage, output signal range, and process temperature ratings are model-configuration-dependent. Contact us with your full tag specification sheet for confirmation before ordering.

Solving the Discontinued Hardware Crisis

The FU20-20-T1-NPT was designed for integration into Yokogawa's ADMAG-era flow measurement infrastructure — systems that remain operational in chemical processing, water treatment, and oil & gas facilities worldwide. These installations were engineered for 20–30 year service lives, and many are still mid-lifecycle.

Facilities that have adopted a structured obsolete-parts inventory strategy — maintaining 1–3 critical spare units per aging loop — consistently extend asset service life by 5 to 10 years beyond OEM support end dates. This is not a workaround. It is a recognized maintenance discipline in ISO 55000-aligned asset management frameworks. The FU20-20-T1-NPT, properly stored and verified, is a direct drop-in for failed units in existing installations. No loop redesign. No re-commissioning. No capital project.

Condition & Reliability Assurance

Sourcing obsolete instrumentation from unverified channels introduces risk that can exceed the cost of the part itself. DriveKNMS applies a 5-step QA protocol to every FU20-20-T1-NPT unit before dispatch review:

• Step 1 – Electrolytic Capacitor Inspection: Internal capacitors are inspected for bulging, leakage, and ESR degradation — the primary failure mode in aged electronic assemblies.
• Step 2 – Firmware Version Verification: Where accessible, firmware revision is confirmed against known compatible versions for the target system integration.
• Step 3 – Pin and Terminal Corrosion Check: All electrical connection points are inspected under magnification for oxidation, pitting, and mechanical deformation.
• Step 4 – Physical Integrity Assessment: Housing, transducer faces, and process connections are inspected for cracks, impact damage, and seal condition.
• Step 5 – Functional Bench Test: Where test infrastructure permits, units are powered and signal output is verified prior to packaging.

Units are shipped in anti-static packaging with individual inspection records. Condition grade (New Surplus, Refurbished, or Tested Used) is disclosed on every order confirmation.

Key Features for System Maintenance

• Drop-in Replacement: The FU20-20-T1-NPT installs directly into existing pipe configurations and wiring terminations. No mechanical modification required.
• No Reprogramming Required: Compatible with existing ADMAG transmitter configurations. Maintenance teams do not need to engage control system engineers for a standard sensor swap.
• Avoids Engineering Rework Costs: Retaining the original sensor model eliminates the need for loop recalculation, P&ID revision, or HAZOP re-review in safety-classified installations.
• Long-Term Spares Strategy: Purchasing 2–3 units now, while RFQ-reviewed sourcing status exists, provides a multi-year maintenance buffer at a fraction of the cost of a single loop replacement project.

Q: Can you source this part if it is not available for RFQ review?
