摘要
The instrumented indentation measurement system includes an indentation device (1), a loading mechanism (2), a table (3) for the sample, an analogue-digital converter (4) and a computer (5). The essence of the indentation device (1) consists in the fact that inside the housing (6) there is arranged a holder (15) for the displacement sensor (19), rigidly connected to the housing (6) in which there is slidably positioned rod (20) passing to the displacement sensor (19) arranged in the holder (15) in the axis of the indenter (13). The movabte pushing segment (10), in the upper part of the housing (6), is equipped with supports extending around the holder (15) and engaging with the central pressure plate (23) arranged slidably in the housing (6) and bearing at least one first load cell (25) with deformable protrusions (26). These protrusions (26) via the gap (27) abut the lower pressure plate (28) arranged slidably in the housing (6) and connected with the holder (12) of the indenter (13), wherein between the lower pressure plate (28) and the facing (7) there is arranged a first resilient member (30) and the central pressure plate (23) and the lower pressure plate (28) are provided with holes for passage of the rod (20) to the holder. (15). The indentation device (1) is created in two preferred embodiments for use with any kind of loading mechanism (2) and for use without a loading mechanism (2) during manual application. The design of the indentation device (1) allows for the accurate measurement of displacement of the indenter (13) without the deformational influence on the measurement components, with adequate accuracy over a wide load range. The device is durable, allowing for its outdoor use including the aggressive environments.
