Conmatic IMC Soil Consolidation System, HM-5480.3F

Humboldt's HM-5480.3F Conmatic IMC is an automatic controller for performing incremental, CRS, and Swell tests. Automatic testing will free up technicians for other tasks and reduce man power requirements of the testing procedures by more than half. IMC allows consolidation tests in the following modes of operation; constant load/stress, constant rate of loading, and constant rate of strain.

One Conmatic IMC automated system can replace the production of several manual machines:

• Incremental according to (ASTM D2435) Method B, where successive load increments are applied through 100% primary consolidation.
• Constant rate of strain (ASTM D4186) with controlled back pressure.
• Swell or collapse of soil (ASTM D4546) Method A & B.

Once a sample has been placed onto the test platform and the test conditions set, the Conmatic IMC performs all consolidation tests, including moving to the next stress level, without operator assistance.
The system automatically moves through the different test parameters specified by the user with incremental consolidation tests typically being completed in 24 to 48 hours. Tests can be done with our NEXT PC software or without it if a PC is not available. The Humboldt NEXT software with the HM-5100SW Consolidation module uses sample deformation readings taken from the displacement transducer and load readings from the load cell to maintain a constant applied stress to the sample throughout the test. Testing data is recorded and displayed in real-time on the screen while test data is stored and calculations are performed automatically. Humboldt‘s NEXT software with the HM-5100SW Consolidation module provides:

• Live test data tabulation and live graphing capabilities (real-time).
• Complete test reporting including all calculations and graphs required for testing.
• Review and exporting of tests using Microsoft Excel (CSV) format.
• Smart Test Function: automatically picks up where it left off if the test was not finished due to unexpected events.

The unique design of the Conmatic IMC system enables the user to connect multiple Conmatic IMC units to a single computer when connected via a LAN-network.

Computer Control
NEXT software and the enhanced Consolidation module, HM-5100SW, is included with the Conmatic IMC automated machine. This software provides robust machine control, calibration, data acquisition and report generation for those using a computer to control testing operations. In addition, operators have the ability to view and control testing operations from the controlling PC, while also providing report generating capabilities using the test-specific software module.
Whether you are controlling a single, or multiple machines, the HM-5475 and the HM-5480 Conmatic IMC, in conjunction with the NEXT testing software, provides a complete solution for the acquisition, recording and presentation of testing data in data tabulation and graphic chart formats with the following:

• Machine control, and data acquisition via networked computer.
• Provides the ability to use Humboldt‘s Next Software's, advanced test-specific modules.
• Real-time graph chart and numerical display of tests via computer display.
• Effective sampling rate up to 50 readings per second.
• Stores unlimited tests with up to 3000 points per test.
• Up to 255 individual tests can be run simultaneously from a single PC.
• Provides advanced graphing capabilities.
• Provides full-unit customization.
• Reports can be exported to Excel or a CSV file, if desired, and Humboldt can provide custom integration/export solutions for LIMS, EQuIS, gINT, as well.
• Stand-Alone reports are available in Excel (CSV) format.

HM-4151A-Air/Water Bladder Cylinder
The Humboldt Air/Water Bladder Cylinder is used to deliver pressurized water to the CRS cell. The bladder acts as a reservoir and interface between the compressed air, used as the pressure source, and the water, which is used as the pressurizing medium for the sample. The cylinder will operate continuously to a maximum pressure of 150 psi (1000 kPa). It is constructed of anodized aluminum top and bottom plates, acrylic cylinder, and a Viton bladder.

HM-4145 Pressure Controller – Manual
The HM-4145 Stand-alone Pressure Controller and readouts for UU (Unconsolidated Undrained) triaxial & CRS pressure applications. It can be used with the HM-4151A. Controls include: a digital readout pressure meter, pressure regulator, water supply and pressure outlets. Operate to a maximum pressure of 150 psi (1000 kPa).
