Calibration is necessary before the installation of an AC-operated linear position sensor to ensure accuracy, says Macro Sensors (Pennsauken, NJ). Calibration corrects any slight variances between sensors, helping to improve repeatability. Because of the linearity of LVDT Sensor output, a two-point calibration is simple. In applications where the LVDT is used on both sides of null, the calibration points should span the entire range of measurement. Traditionally, AC-operated LVDT Sensors were not easy to calibrate. Modern signal conditioners, like Macro Sensors EAZY CAL™ Signal Conditioner , offer a virtually effortless front panel fingertip routine for easy field calibration.
