SF15 Force Sensor Calibration Guide

• Sensor Overview: SF15 is a strain gauge-based force sensor with a measurement range of 0–500 N, resolution 0.01 N, accuracy ±0.5% FS, and operating temperature -20°C to 80°C, designed for precise force measurement in industrial and automation applications.
• Calibration Equipment: Requires a reference load cell (≥0.1% accuracy), digital multimeter, computer, and calibration software to ensure accurate data acquisition and processing.
• Calibration Process: Includes cleaning and zeroing the system, applying known forces across the full range, recording resistance changes, and calculating calibration coefficients (sensitivity and offset) using software.
• Key Factors: Calibration accuracy depends on load cell precision, temperature consistency, sensor linearity, stable mounting, and minimized electrical noise. Calibration should be performed under actual operating conditions.
• Maintenance: Calibration frequency should be defined based on application accuracy requirements, especially for high-precision systems.
• Applications: Suitable for industrial automation, robotics, medical devices, weighing systems, and torque measurement.
