Dual-Bridge & Fatigue-Rated Pancake Load Cells
Two independent Wheatstone bridges can feed separate acquisition channels. A fatigue configuration additionally requires a defined force spectrum, mean load and fixture design; adding a second bridge does not establish fatigue life.
Confirm the bolt circle and center thread.

| MT-PLC-FAT | 1.25–2,000 kN 281–449,618 lbf | Project drawing required | Cell / base / button stack reviewed separately | Metric / UNF / UN thread review | BCD, count, bore, counterbore and pilot on released drawing | Sensor and full assembly mass confirmed before freight |
For an installed replacement, supply the original drawing or measured envelope. Original manufacturer reference dimensions are labeled separately; they are not approved MT-PLC dimensions.

Define the load envelope behind the number.
- Define mean force, alternating amplitude, frequency, waveform and required cycle count.
- For a 10^8-cycle request, specify the full test spectrum and request the corresponding validation evidence.
- Specify two acquisition chains and bridge-to-bridge comparison limits. Functional safety certification is a separate system requirement.
Reference review: Interface 1000 / 1100; HBK U10M project-specific review. Original brand references do not establish fit, approval or affiliation.
Questions to settle before the fixture is frozen.
Are the bridge excitations and outputs independent?
Define mean force, alternating amplitude, frequency, waveform and required cycle count.
At what mean load and amplitude is cycle life assessed?
For a 10^8-cycle request, specify the full test spectrum and request the corresponding validation evidence.
Does dual-bridge hardware establish a safety integrity rating?
Specify two acquisition chains and bridge-to-bridge comparison limits. Functional safety certification is a separate system requirement.
Packed mass and freight are itemized.
Compact models (1–25 kN): DHL Express parcel quotation with destination-specific transit estimates. Intermediate models (over 25 to under 50 kN): shipping assessed by packed mass. Heavy-capacity models (50–2,000 kN), including base assemblies: itemized DHL/FedEx heavy air freight on the formal Proforma Invoice. Availability, dispatch, customs and final freight are confirmed for the actual assembly and destination.
Separate cycle-life evidence from two-channel measurement.
| Decision | Review input / acceptance |
|---|---|
| Fatigue spectrum | Specify mean load, alternating amplitude, waveform, frequency, cycles and environment. |
| Independent bridges | Define excitation/output/connector for each bridge and the channel comparison strategy. |
| Verification evidence | Request the agreed load spectrum and test/inspection record; 10^8 cycles is a review target, not an unqualified life guarantee. |
The engineering brief defines a request. The released datasheet and STEP file are supplied for the reviewed part and revision.
Approve the calibration boundary with the fixture.
Specify whether the calibration covers the sensor alone or the sensor, mounting base, button, cable and amplifier as a system. Request traceability and uncertainty for the actual force range and direction.
Review calibration, standards and record requirements ↗For a replacement, retain the full original model, both drawing revisions and the receiving instrument configuration. Machine verification is a separate acceptance step.
Request a calibration plan ↗Bring the load path.
We’ll review the fit.
Send your capacity, center thread and mounting envelope. Include the full original part number when replacing an installed sensor.
CAD and test reports are supplied for the agreed configuration. No generic drawing is presented as an approved production part.
