Product Introduction
The is a signal converter / amplifier used in ABB Pressductor and Millmate tension or rolling force measurement systems. It receives low-level signals from Pressductor load cells and converts them into stable analog outputs for PLCs, drives, or tension controllers.
This unit is typically applied in paper machines, film and foil converting lines, metal strip processing, and rolling mills. Because PFVK135 is an older ABB series designation, the exact order number, revision, input range, and output signal should be confirmed from the physical nameplate before replacement.
Key Technical Specifications

Note: Exact electrical ratings, terminal layout, and output scaling must be confirmed from the OEM manual and the unit nameplate.
Quality Control Process
- Verify on the nameplate and confirm the order number and revision.
- Inspect housing, terminals, DIN-rail clips, and connector pins for damage or corrosion.
- Apply the correct supply voltage and verify power-up LED indicators.
- Simulate a Pressductor sensor input and check analog output linearity with a multimeter.
- Confirm zero offset, span adjustment, and anti-static packaging before dispatch.
Replacement Pitfall Guide
- Don’t replace it with a generic 4–20 mA amplifier. Pressductor sensors use a special low-level AC/mV-type signal; a standard amplifier will not match the excitation and input characteristics.
- Confirm the successor model. PFVK135 is an older series; replacement may require a PFEA, PFCA, MC400, or other Millmate unit depending on system configuration.
- Check input/output scaling. Incorrect span or zero settings will cause tension reading drift even if the load cell is healthy.
- Verify sensor compatibility. Ensure the replacement supports the same Pressductor load cell series and cable length.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| ABB | ABB | Direct | Match order number, revision, and I/O configuration. |
| ABB | ABB PFEA / PFCA / MC400 series | Needs Adaptation | Confirm sensor compatibility, output type, and system calibration. |
| ABB | Generic analog signal amplifier | Not Recommended | Pressductor input and excitation requirements are not standard. |
Benchmark notes:
- Input: Low-level Pressductor load cell signal.
- Output: Typically analog 0–10 V / 4–20 mA, subject to nameplate confirmation.
- Typical use: Signal conditioning for PFTL / PFCL / PFVL Pressductor sensors.
