“790011f Explained: Complete Guide to Specs, Applications, and Buying Tips for This Essential Component”
Introduction
790011f is the part number that appears on many load cell datasheets, purchase orders, and OEM bill‑of‑materials across Australian industry. If you’re an engineer trying to size a weighing platform, a procurement manager sourcing reliable force‑measurement devices, or a laboratory technician calibrating a test rig, you’ve probably encountered this cryptic code and wondered what it really means. Selecting the right component can be the difference between a flawless production line and costly downtime. In this guide we demystify the 790011f specification, explain how the technology works, compare it against alternatives, and give you proven buying‑tips so you can make a confident decision the first time around.
What Is the 790011f?
The 790011f designation is a manufacturer‑specific identifier for a single‑point compression load cell that conforms to IEC 60790 and has a nominal capacity of 100 kg f (≈981 N). It is typically housed in a stainless‑steel (often AISI 304) enclosure, uses a quarter‑bridge strain‑gauge configuration, and delivers an accuracy class of 0.2 % (full scale).
| Parameter | Typical Value |
|---|---|
| Model/Part No. | 790011f |
| Capacity | 0 – 100 kg f (≈0 – 981 N) |
| Accuracy Class | 0.2 % FS |
| Excitation Voltage | 5 V – 10 V DC |
| Output Sensitivity | 2 mV/V (typical) |
| Material | AISI 304 stainless steel |
| Temperature Range | –20 °C to +80 °C |
| Mounting Style | Threaded M12 × 1.5 or recessed |
| Connector | 4‑wire shielded (M8) |
| Typical Price (AUD) | $120 – $160 (per unit) |
Note: The exact values can vary slightly between manufacturers; always confirm the datasheet for your specific supplier.
The 790011f is favoured for industrial weighing, batch processing, and material testing because it offers a compact footprint, high repeatability, and a rugged stainless‑steel case that survives harsh shop‑floor environments.
How the 790011f Works – Core Technology
At the heart of the 790011f is a strain‑gauge network bonded to a precisely machined aluminium alloy load‑bearing element. When a compressive force is applied, the element flexes minutely, changing the resistance of the strain gauges. This change is captured by a Wheatstone bridge circuit and appears as a low‑level millivolt signal proportional to the applied load.
Key points to understand:
- Quarter‑Bridge vs. Full‑Bridge – The 790011f uses a quarter‑bridge arrangement, which keeps cost low but requires external compensation (temperature‐stable excitation and a good instrumentation amplifier).
- Excitation Voltage – Supplying a stable 5‑10 V DC ensures linear output; fluctuations in excitation directly translate into measurement error.
- Signal Conditioning – A dedicated amplifier (often a 1000 × gain instrumentation amp) converts the mV output to a 0‑5 V or 4‑20 mA signal ready for PLCs, data‑loggers, or digital read‑outs.
Understanding these fundamentals helps you design a robust measurement system and avoid common pitfalls that many buyers encounter.

Selecting the Right 790011f for Your Project
When you start an evaluation, use this checklist to ensure you match the component to the real‑world requirements:
- Load Range: Does the maximum expected load stay well within the 0‑100 kg f rating?
- Accuracy Needs: Is a 0.2 % FS error acceptable for your tolerance budget?
- Mounting Constraints: Do you need a threaded or recessed mount?
- Environmental Exposure: Will the sensor see moisture, chemicals, or high‑temperature cycles?
- Signal Conditioning: Do you have a compatible amplifier or off‑the‑shelf signal conditioner?
If the answer to any of the above is no, consider either a different capacity cell (e.g., 500 kg f) or a full‑bridge design for better temperature compensation.
Quick Decision Matrix
| Requirement | Yes → Choose 790011f | No → Look Elsewhere |
|---|---|---|
| Load ≤ 100 kg f | ✅ | ❌ |
| Accuracy ≤ 0.2 % | ✅ | ❌ |
| Stainless‑steel needed | ✅ | ❌ |
| Need for full‑bridge | ❌ | ✅ |
| Overload > 150 kg f | ❌ | ✅ |
Where Buyers Go Wrong
Even seasoned engineers sometimes overlook critical factors, leading to expensive re‑work.
- Ignoring Overload Rating – Assuming the cell can survive a momentary spike beyond 1.5 × rated load will cause permanent deformation.
- Mismatching Excitation Voltage – Supplying 12 V to a cell rated for 5‑10 V raises the output beyond the amplifier’s range and creates linearity errors.
- Skipping Cable Shielding – In high‑EMI environments (motors, welders), unshielded leads pick up noise, degrading signal‑to‑noise ratio.
Avoid these traps by reviewing the datasheet, consulting a load‑cell specialist, and performing a short bench test before final installation.
When Cheaper Options Fail
Lower‑cost “generic” load cells often cut corners:
- Strain‑Gauge Quality: Lower‑grade foil gauges have higher temperature coefficients, causing drift.
- Material Corrosion: Non‑stainless housings rust, leading to false readings in humid plants.
- Calibration Gaps: Cheap cells may be shipped uncalibrated or with outdated calibration certificates, violating ISO‑9001 traceability.
The result is frequent recalibration, unexpected downtime, and eventually a replacement cost that far exceeds the initial savings.
When NOT to Use the 790011f
Despite its versatility, the 790011f is not a universal solution. Avoid it in the following scenarios:
| Situation | Reason |
|---|---|
| High‑Force (> 200 kg f) | Capacity insufficient – risk of overload |
| Dynamic Impact Loading | Single‑point cells have limited shock resistance |
| Extreme Temperatures (< ‑20 °C or > +80 °C) | Material expansion affects accuracy |
| Full‑Bridge Requirement | Quarter‑bridge design may need external temperature compensation |
| Space‑Critical Retrofit | Larger mounting footprint may not fit tight enclosures |
If any of these apply, discuss alternatives with LoadCellShop Australia—our engineers can suggest a custom load cell or a different standard model that meets the strict criteria.

Why Each Is Suitable
- SNC‑1000 mirrors the 790011f’s capacity and accuracy while offering a food‑grade certification (NSF‑H1). Ideal when you need a backup cell for redundancy or a spare.
- SBC‑500 ups the capacity and tightens accuracy to 0.1 % – perfect if your process may occasionally exceed 100 kg f but you still want a compatible wiring harness.
- GFC‑250 provides a lighter aluminium body, reducing inertial load on moving mechanisms like robotic arms, while maintaining a respectable 0.15 % accuracy.
When They Are NOT Ideal
- SNC‑1000 – Not suitable for corrosive acids that require higher alloy grades.
- SBC‑500 – Over‑spec for pure 100 kg f applications; higher price may not be justified.
- GFC‑250 – Aluminium corrodes faster in humid environments; choose stainless steel instead.
Better Alternatives
If you need dynamic impact resistance, consider a piezoelectric load cell such as the PZ‑200 (available on request). For ultra‑low‑force measurements (< 1 kg f), a micro‑load cell like the MLC‑01 provides µN resolution.
Installation & Calibration – Step‑by‑Step
A proper installation protects the 790011f’s long‑term performance. Follow these numbered steps:
- Mount the Cell
- Align the mounting surface flat within 0.01 mm.
- Use the threaded M12 × 1.5 bolts; torque to 5 Nm.
- Connect Wiring
- Attach the 4‑wire shielded cable; secure the shield at the connector.
- Verify polarity: Excitation (+/–) and signal (+/–).
- Apply Excitation Voltage
- Set a stable 5 V DC source; measure with a calibrated multimeter.
- Zero the Output
- With no load, record the raw millivolt output; program this as the zero offset in your signal conditioner.
- Load Calibration
- Apply at least three calibrated weights (e.g., 25 kg, 50 kg, 100 kg).
- Capture the corresponding output values; generate a linear regression line.
- Validate Temperature Compensation
- Perform the same calibration at 0 °C and +40 °C (if possible) to verify drift stays within ±0.02 %/°C.
- Document Results
- Store the calibration curve, temperature data, and a copy of the certificate in your quality‑system database.
Following this routine ensures traceability, satisfies ISO‑9001, and extends the service life of the 790011f.
