Regular Calibration: Using metrologically certified standard weights or force gauges, calibrate the sensor at multiple points (usually no fewer than 5 points, including zero and full scale) across its entire range. The calibration process establishes a precise correspondence between the sensor output and the actual force value (linearity, hysteresis, and repeatability compensation), and the parameters are then input into the instrument.
Environmental Compensation: High-quality S-type sensors incorporate a temperature compensation resistor, effectively reducing zero-point drift and sensitivity drift caused by temperature changes. In environments with extreme temperatures or large temperature differences, pay attention to the temperature impact specifications in the sensor datasheet.
Interference Elimination: Ensure the sensor and connecting cables are kept away from sources of electromagnetic interference such as high-voltage power lines and frequency converters. Proper grounding is crucial. Using shielded cables and grounding the shielding layer at a single point (usually at the instrument end) effectively suppresses electromagnetic noise interference.
Avoid Overload and Shock: Never exceed the sensor's rated range (Safe Overload, Ultimate Overload) in terms of pressure or impact, as this will result in permanent damage or decreased accuracy. Software or mechanical limit devices can be set in the system for protection.
