Abstract
A high-pressure press includes a pressure vessel surrounded by a force-absorbing press frame. The high-pressure press also includes a detection structure for detecting changes in length of at least one column comprised in the press frame, the changes in length depending on the pressure inside the pressure vessel. The detection structure includes a limit switch, which is adapted to detect if the change in length of the column has reached a threshold value and, in that case, interrupt a pressing operation in progress and reduce the pressure inside the pressure vessel.
