Rock pressure expansion tester
PRoduct description
The rock expansion pressure tester uses digital display of force values, manually rotates the screw to apply pressure, reads vertical displacement deformation with a dial gauge, and is equipped with testing devices such as permeable plates. The instrument is small in size and easy to operate. Suitable for expansion pressure tests under constant volume conditions in various rock swelling tests.
Automatic data collection system, computer software automatically collects experimental data, saving manpower and increasing the accuracy of experimental data. This automatic data acquisition system mainly consists of a multi-channel acquisition instrument, computer data acquisition software, displacement and force sensors, etc.
Multi channel acquisition instrument and computer data acquisition software functions
Real time collection, monitoring, displacement deformation, and curve graphics; Can achieve multi-channel acquisition of displacement; The experimental data can be freely exported for analysis purposes; The test time can be preset arbitrarily, and the test will automatically stop when the time comes. The sampling time period can be set arbitrarily.
