50KN CBR marshall Testing Machine
Model: CSRN-50
Product Name : 50KN CBR marshall Testing Machine
Fully Automated Multifunction Load Frame
Application:
Automatic CBR Test Machine
is designed for performing laboratory evaluation of the CBR value of highway sub-bases and sub-grade, and determination of the strength of cohesive materials which have maximum particle sizes less than 19 mm.
The Machine is composed of a robust and compact two column frame with adjustable upper crossbeam driven by an electro-mechanical ram with a maximum capacity of 50 kN and a data acquisition and processing system.
The Machine is designed to load the penetration piston into the soil sample at a constant rate to measure the applied load and piston penetration at predetermined intervals. The ram speed can be set between 0.5 mm/min to 5 mm/min by using the TCM digital readout unit. This main feature allows the user to perform tests complying to BS, EN, ASTM or AASHTO standards with the same machine.
Main Features.
* Can make the test with displacement control
* Real time display of test graph.
* 4 analog channels for load cell and displacement sensors
* Can control second frame
* Calibration function for channels.
* Programmable digital gain adjustment for load-cell and potentiometric sensors, voltage and current transmitters
* Closed-loop PID for steady pace rate
* Calculates corrected CBR value at 2.5 and 5 mm the digital unit saves the load value at user defined displacement values such as 0.625, 1.25, 1.875, 2.5, 3.75, 5, 7.5,10, 12.5 mm
* The load corresponds to the displacements corrected respect to the linear region of the data has also saved
* The % CBR at 2.5 mm and % CBR at 5 mm is also automatically calculated and saved.
