Automatic Marshall Stability Test Machine

Specification:

• The 50 kN capacity Automatic Marshall Stability Test Machine is used to determine the maximum load and flow values of bituminous mixtures.
• The machine comprises of a robust and compact two column frame with adjustable upper cross beam.
• The machine can be hand operated by a lateral hand wheel for calibration purposes.
• For safety, the up and down travel of the lower platen is limited the use of limit switches.
• Rapid adjustment of the platen is controlled using the up and down buttons on the front panel of the machine.
• The speed of the lower platen can be adjusted between 6 mm/min to 60 mm/min using the data acquisition and control unit.
• The unit is a bench mounting compression frame with motor and worm gear housed within the base unit.

Features:

• Automatically calculates flow and stability values.
• Can make test with displacement and limited load control.
• Real time display of test graph.
• CPU card with 32-bit Arm RISC architecture.
• Permanent storage capacity up to 10000 test results.
• 4 analog channels, 2 channels are active for marshall test.
• Programmable digital gain adjustment for load-cell, pressure transducers, strain-gauge based sensors, potentiometric sensors, voltage and current transmitters.
• 1/256000 points resolution per channel.
• 10 data per second sample rate for each channel.
