Description

全自动沥青针入度仪

Apparatus for determination of the needle penetration.

At this the path a standard needle penetrates in the sample under standardized conditions (load, time, temperature) is measured.

The penetration depth of the needle is determined with an electronic measuring system, which is separated from the plunger during the test. This and the free guidance of the plunger the influence to load and friction is virtually eliminated. Before each start of the test the measuring system automatically referenced, then the penetration needle moved up to the sample with an electric drive, which is moved by finely adjustable joystick (an ultra-bright LED lamp included). Then the plunger is approved by an automatic device and blocked again after the testing period. The test result is displayed on the digital display. The plunger can easily be removed to calibrate its weight.


20-20670 Automatic Digital Penetrometer

The penetration depth of the penetration needle is de-termined with an electronic position measuring system, which is decoupled from the plunger during the test. An influence on the load and friction is excluded, because of this an the free guidance of the plunger. 


The run-up and touch down of the needle are carried out automatically via the measurement system. Manual joy-stick mode is also possible. Then the plunger is enabled by an automatic device and blocked again after the testing period. The test result is displayed on the graphi-cal touch display. The plunger can easily be removed to calibrate its weight.
