Theory of Operation

ISU ModuleThe heart of every SmartTool Technologies protractor and OEM inclinometer is an innovative, noncontact capacitive sensor that measures angles with respect to gravity over a full 360° range. The sensor is comprised of a special disk-shaped printed circuit board (PCB) and an aluminum housing which is sealed to form a cylindrical cavity. The cavity is one-half filled with a special liquid, which causes the capacitive characteristics of the PCB to change as the unit is rotated. By precisely measuring these capacitive characteristics, the exact orientation of the sensor can be determined.

Every SmartTool Technologies protractor and inclinometer is fully calibrated during the manufacturing process, and special algorithms in the microprocessor improve measurement accuracy and compensate for changes in sensor output with temperature.
