How the Befour PS 6600 Works – Core Concepts You Must Know
Before diving into the calibration routine, let’s demystify the underlying technology.
| Component | Role | Key Technical Term |
|---|---|---|
| Strain‑Gauge Bridge | Converts mechanical deformation into an electrical voltage. | Bridge Output |
| Excitation Supply | Provides a stable voltage (typically 10 V) to the bridge. | Excitation Voltage |
| Signal Conditioner | Amplifies the millivolt bridge signal to a usable range (e.g., 0‑10 V). | Gain Adjustment |
| Digital Display & Interface | Shows real‑time force readings and stores calibration data. | Zero Offset |
| Temperature Sensor | Monitors ambient temperature for compensation. | Temperature Compensation |
The Measurement Chain
- Force → Strain – An applied load deforms the elastic element of the load cell, altering the resistance of the bonded strain gauges.
- Resistance → Voltage – The Wheatstone bridge translates the resistance change into a proportional voltage (mV/V).
- Voltage → Digital – The PS 6600’s conditioner amplifies and digitizes the signal, applying zero balance and gain corrections.
- Display → Data – The software logs each reading, enabling post‑test analysis and certification.
Understanding each link is essential because calibration adjusts the zero balance, span (gain), and temperature coefficient – the three parameters that define accuracy class.
Why Calibration Matters – The Business Case
- Regulatory compliance – Many Australian standards (AS 2870, ISO 15197) require periodic verification of force measurement equipment.
- Product quality – A ±0.1 % error on a 10 kN test can shift a component’s safety factor dramatically.
- Cost avoidance – Uncalibrated load cells are a leading cause of scrap in metal forming, packaging, and pharmaceutical tablet compression.
By executing a robust befour ps 6600 calibration schedule, you protect your bottom line and maintain traceability to national metrology institutes.
Step‑by‑Step Befour PS 6600 Calibration Procedure
The following numbered steps are designed for a four‑point calibration (typical for Class 0.5 accuracy) but can be adapted to six‑point methods for higher precision.
Preparation (Pre‑Calibration)
- Warm‑up the PS 6600 – Power on the unit and allow at least 30 minutes for thermal equilibrium.
- Check the environment – Ensure ambient temperature is within the instrument’s range (15‑30 °C) and that vibration is < 0.2 g.
- Gather reference masses – Use certified calibration masses covering 0 %, 25 %, 50 %, and 100 % of the load cell’s rated capacity. Verify each mass’s certificate for traceability.
Calibration Sequence
| Step | Action | Critical Parameter |
|---|---|---|
| 1 | Zero Balance Check – With no load applied, press “Zero” on the PS 6600. | Zero Offset must be ≤ ±0.02 % FS (Full Scale). |
| 2 | Apply 25 % Load – Place the first certified mass on the test fixture. Record the displayed value. | Span error should be ≤ ±0.05 % FS. |
| 3 | Apply 50 % Load – Replace with the second mass; record. | Verify linearity between 25 % and 50 % points. |
| 4 | Apply 100 % Load – Load the maximum certified mass; record. | Full‑scale error ≤ ±0.10 % FS. |
| 5 | Temperature Compensation – If the PS 6600 features a built‑in temperature sensor, note the ambient reading and repeat steps 1‑4 at a second temperature (e.g., ±5 °C). | Calculate temperature coefficient (µV/°C). |
| 6 | Generate Calibration Report – Use the software’s “Export” function to produce a PDF with raw data, regression analysis, and a calibration certificate. | Ensure the report includes traceability chain and expiration date (typically 12 months). |
Post‑Calibration Validation
- Repeatability Test – Load the 50 % mass three times without removing it; standard deviation must be < 0.01 % FS.
- Hysteresis Check – Unload from full‑scale to zero and record the zero offset again; deviation must be within the same tolerance as the initial zero.
If any criterion is missed, the PS 6600’s gain or zero settings can be fine‑tuned via the “Calibration” menu, then the sequence repeated.
Common Mistakes & How to Avoid Them
Where Buyers Go Wrong
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Skipping the warm‑up period | Drift up to 0.3 % FS due to internal temperature gradients. | Always allow ≥ 30 min for thermal stabilization. |
| Using un‑certified masses | Lack of traceability, invalid test reports. | Purchase NIST‑traceable masses from reputable suppliers (e.g., LoadCellShop). |
| Neglecting temperature compensation | Errors of up to 0.2 %/°C in harsh environments. | Perform dual‑temperature calibrations or use a calibrated temperature chamber. |
| Relying on “auto‑zero” without verification | False zero set‑points caused by mechanical preload. | Manually verify zero balance after each power‑cycle. |
| Mixing different load cell types on the same PS 6600 | Cross‑talk and gain mismatch. | Use dedicated signal conditioners or switchable input ranges for each cell type. |
When Cheaper Options Fail
Low‑cost “laboratory” load cell testers often:
- Lack a stable excitation source, causing voltage fluctuations.
- Offer limited resolution (e.g., 12‑bit vs. 24‑bit ADC in the PS 6600).
- Provide no temperature compensation or traceable calibration certificates.
The result is a seemingly functional setup that fails during audit or when the load cell is subjected to real‑world stresses. For critical applications—automotive crash testing, pharmaceutical tablet compression, or aerospace component validation—investing in a proven system like the Befour PS 6600 pays for itself through reduced scrap and compliance penalties.
When NOT to Use Certain Products
| Situation | Unsuitable Product | Why It’s Inappropriate |
|---|---|---|
| Measuring dynamic impact forces (> 200 Hz) | Standard static load cell (e.g., 0‑5 kN shear beam) | Bandwidth insufficient; signal distortion. |
| Extreme high‑temperature environments (> 120 °C) | Aluminum strain‑gauge load cells | Thermal expansion changes gauge factor, causing drift. |
| Ultra‑high precision mass flow (±0.001 % FS) | General‑purpose load cells | Accuracy class too low; noise floor dominates. |
| Portable field testing with no power source | Benchtop PS 6600 (requires mains) | Not battery‑operable; impractical for field. |
In these cases, consider custom load cells, high‑frequency piezoelectric transducers, or portable battery‑powered calibrators—available through LoadCellShop’s custom load cell service.
Selection Guide – Picking the Right Load Cell for the PS 6600
When pairing a load cell with the Befour PS 6600, match capacity, accuracy class, and material to your application.
| Capacity Range | Recommended Cell Type | Typical Accuracy | Preferred Materials |
|---|---|---|---|
| 0‑5 kN | Miniature shear beam | Class 0.5 (±0.5 % FS) | Stainless steel (SS 304) |
| 5‑20 kN | Compression (cylindrical) | Class 0.2 (±0.2 % FS) | Alloy 7075‑T6 |
| 20‑100 kN | S-Type (dual‑element) | Class 0.1 (±0.1 % FS) | Stainless steel (SS 316) |
| 100‑500 kN | Punch‑type @ 150 kN | Class 0.05 (±0.05 % FS) | Inconel 718 |
Tip: Choose a load cell whose nominal capacity is 1.5–2× the maximum expected load to keep non‑linearity within spec.

Installation & Best‑Practice Checklist
- Mounting – Use torque‑controlled fasteners (≤ 2 Nm) to avoid pre‑loading the cell.
- Wiring – Follow the four‑wire (full‑bridge) scheme; label each conductor to prevent phase reversal.
- Shielding – Route cables away from high‑current motors; use braided shield grounded at the PS 6600 chassis.
- Environmental Protection – If operating outdoors, fit a IP‑67 enclosure and use a heated hutch for temperature control.
- Documentation – Log every installation step in a Calibration Management System (CMS) for audit trails.
Mistakes to Avoid – Real‑World Lessons
- Over‑tightening the load cell mount introduces a permanent offset; always torque to the manufacturer’s spec.
- Re‑using old calibration certificates after a major repair voids traceability; obtain a fresh certificate each time.
- Ignoring cable length limits – beyond 5 m the bridge signal attenuates, necessitating a remote signal conditioner.
