摘要： Indentation head system (1) for an indentation instrument (100), comprising:
- an indenter tip (3) adapted to be brought into contact with a surface of a sample (5) along at least an indentation axis (A);
- a reference element (9) arranged to support said indenter tip (3).
According to the invention, said indentation head system (1) further comprises:
- a zero-level sensor (17) arranged to output a signal indicating whether said indenter tip (3) is displaced with respect to said reference element (9) from a neutral relative position, considered along said indentation axis (A);
- an elastic element (19) connected between said indenter tip (3) and an actuator (21) with known elongation, said actuator (21) being connected to said reference element (9);
- a controller (25) adapted to receive signals from said zero-level sensor (17) to carry out servo control of said actuator (21) based on output of said zero-level sensor (17) and said known elongation of said actuator (21) such that said zero-level sensor (17) outputs a signal corresponding to a substantially zero displacement of said indenter tip (3) from said neutral relative position, said controller furthermore being adapted to calculate a force applied by said indenter tip (3) to said sample (5) on the basis of an output of said displacement sensor (23) and an elastic coefficient (k) of said elastic element (19).
