How to Calibrate an AC-operated LVDT Linear Position Sensor

Calibration is necessary before the installation of an AC- operated linear position sensor to ensure accuracy. Calibration corrects any slight variances between sensors, helping to improve repeatability. Because of the linearity of LVDT Sensor output, a simple two-point calibration is simple. Two points should be as far apart as possible, but within the linear range of the LVDT Linear Position Sensor and preferable within the measurement range in which it will be used.
