Unlike 8 mm systems, the 25 mm probe offers a linear range of 12.7 mm, suited for monitoring differential expansion and valve position. System commissioning mandates gap voltage validation; the sensor must be positioned to center the output voltage within the specific linear range defined for the 25 mm Proximitor.
