1. A displacement measuring device (102) for use with a pen needle (100), comprising:
a static part (110) adapted to be removably attached to a body (112) of the pen needle;
a moving part (106) adapted to be removably attached to an actuator (114) of the pen needle;
wherein the displacement measurement device measures displacement between the static part (110) and the moving part (106);
wherein the static part (110) comprises a gripping mechanism to grip the body (112) of the pen needle; and
wherein the moving part (106) comprises a gripping mechanism to grip the actuator (114); wherein the gripping mechanism to grip the actuator is rotatable relative to the gripping mechanism to grip the body of the pen needle while gripping the actuator to rotate together with the actuator; wherein the gripping mechanism to grip the actuator comprises spring channels having springs therein that apply force on first opposing gripping members to grip an outer surface of the actuator.
