Load Frame, CBR (California Bearing Ratio) Automatic

The HM-5150.3F has been specifically designed for those who want a high-quality, CBR and LBR-specific load frame that provides complete control of the testing process. It's single-speed (0.05 inches/minute), (1.27mm/minute) motor delivers precise operation and durability that will last for years.

The HM-5150 allows the operator the choice of operating the test process in a stand-alone mode or from a networked computer. The addition of Humboldt's NEXT software and the HM-5001SW CBR and LBR software module provides complete setup, monitoring and reporting capabilities for a complete testing solution.

The HM-5150 provides two (2) integral and independent data acquisition channels, which can be utilized in stand-alone configurations or accessed through a LAN-networked computer using Humboldt's Next Software. The HM-5150 load frame is built with durable, high-quality components and features the use of a stepper motor, precision gears and gear box to ensure smooth and reliable operation, as well as precise results.

In stand-alone mode, the HM-5150 load frame provides a 7" (178mm) touch-screen controller, giving you finger-tip control of your testing processes, as well as providing real-time, visual views of your data in both tabular and graphic formats. This waterproof, touch screen provides colorful, at-a-glance monitoring of testing functions without the use of a computer. Operators can see all the data in several formats at the machine while the test is running. Data can then be viewed simultaneously or downloaded later to a computer in the lab, in the next room or at a different location, while also providing report generation capabilities from within Humboldt's NEXT software or our enhanced test-specific modules.

Touch-Screen Controller provides:

  • 2-channel data acquisition
  • Hi-res, 7", waterproof, touch-screen provides total control and real-time graphical display of tests
  • Machine /Test control and data acquisition via touch-screen
  • 2 channels provide inputs for standard CBR and LBR tests
  • Calibration of channels to load cells, transducers and other suitable instruments
  • Real-time graphical chart and numerical display of tests via touch-screen display
  • Effective sampling rate of 50 readings per second
  • Stores up to 1000 tests with 3000 points per test
  • 2 USB ports. One in front for data transfer and the rear port is for powering a wireless access point.

When operated from a networked computer the NEXT software provides robust machine and test control, as well as report generation. It also provides the ability to control and monitor multiple machines from a single computer.

The HM-5150 is sold as a Load Frame ONLY, refer to the accessories tab above for items needed to perform CBR tests.
