    Introduction ➝ Mechanical construction A-11 What does a press-fit monitoring module do? The ML85C press-fit monitoring module was specifically developed to monitor press-fit processes, with the aim being to safeguard quality even during the production process. The module monitors two physical quantities (e.g. force and displacement) and their relation to one another. The two measured quantities can also be displayed as the functions of time (force-time or displacement-time diagram).
