Quick Answer
Force gauge calibration applies known NABL-calibrated reference loads (using dead weights or calibrated load cells) to the force gauge at 5 calibration points. The gauge reading is compared against the applied reference force and measurement error and uncertainty are calculated per ISO 376 or manufacturer specifications.
Key Takeaways
- Force gauge calibration range at Prism: 0.1 N to 50 kN (compression and tension).
- Reference standard: NABL-calibrated reference force transducer (Class 0.05 per ISO 376).
- Calibration covers both push (compression) and pull (tension) directions.
- NABL certificate includes sensitivity, linearity, zero drift, and expanded uncertainty.
- Digital force gauges can be calibrated with ±0.3% accuracy; spring scales ±1–2%.
Where Force Gauges Are Used
- Connector and switch insertion/extraction force testing (electronics assembly)
- Door latch and automotive component force testing
- Packaging seal strength and peel force testing
- Spring testing and spring rate measurement
- Ergonomic tool handle force evaluation
- Button and keypad actuation force testing
- Tensile bond strength of adhesives and sealants
- Friction force measurement
Force Gauge Types We Calibrate
Digital Push-Pull Force Gauge
Electronic sensor, digital display, data output. Brands: Shimpo, Mark-10, Imada, Chatillon, Mecmesin.
Mechanical Dial Force Gauge
Spring and dial mechanism. Less accurate but robust. Used where digital display not practical.
Spring Scale (Newton Scale)
Simple spring-based measurement. Range: 1 N to 500 N. Calibrated using NABL reference masses.
Hanging Scale (Steelyard)
Lever-based or spring-based hanging scales. Used in markets and agriculture.
Frequently Asked Questions
How is a force gauge different from a load cell?
A load cell is a sensing element (strain gauge bridge) installed inside a larger system. A force gauge is a complete handheld instrument with display that directly reads force. Force gauges are calibrated the same way — by applying known reference forces and comparing the reading.
Can Prism calibrate force gauges in Newton (N) and kgf?
Yes. Prism calibrates force gauges in any unit: N, kN, kgf, lbf, and tonf. The certificate states results in the instrument's native unit and in SI units (N).
How often should force gauges be calibrated?
Annual calibration is standard for most applications. High-cycle force gauges (used thousands of times per day in production) should be calibrated every 6 months or every 100,000 cycles, whichever comes first.
Does Prism calibrate force gauges up to 50 kN?
Yes. Prism calibrates force gauges up to 50 kN (5 tonnes) using a precision loading frame and NABL-calibrated reference force transducer.
Can a force gauge be calibrated for both push and pull?
Yes. Prism calibrates bi-directional (push-pull) force gauges for both compression and tension loading at each calibration point.
