1. The load cells can also be used as a rudimentary axle counter. 2. The friction of the coated surface is measured using a load cell . 3. Strain gauge load cells convert the load acting on them into electrical signals. 4. The strain gauge load cell is fundamentally a spring optimized for strain measurement. 5. Other technologies used include strain gauges and vibrating wire load cells . 6. Strain gauge load cells are the most common in industry. 7. Typical instrumentation used to measure NVH include microphones, accelerometers and force gauges, or load cells . 8. A load cell is attached to the end of the hammer to record the force. 9. These parameters are measured using several specific tools including inclinometers, load cells and strain gauges. 10. Thus a potential difference is felt between the output or signal leads of the load cell .
