Pressure Hysteresis is the difference between two separate measurements taken at the same pressure but one where the pressure was increasing and the other where the pressure was decreasing.
The hysteresis is caused by the natural reluctance of a pressure sensing material such as a diaphragm to return to its original position, shape or form after being mechanically deformed.
