You can use Humboldt Data Loggers to cost-effectively update your older, non-computerized load frames, direct shear and consolidation machines with computerized data acquisition— increasing lab output, freeing-up technicians and providing more accurate test results. Humboldt’s modular-design, data acquisition concept is designed to give you the most flexi- ble and cost-effective method of data logging for your lab. Rather than having to buy into a large data logging system and then growing into it, Humboldt Data Loggers give you the flexibility and low cost outlay of being able to buy loggers on an "as you grow" basis, increasing your data logging capability as your expansion demands. Humboldt Data Loggers can be used with a wide variety of transducers, load cells and digital indi- cators; and both come with Humboldt’s, highly-re- garded, NEXT software. This software provides robust data acquisition and report generation for those wanting to use a computer to monitor tests and collect test data. In stand-alone mode, these data loggers provide a 7" (178mm) touch-screen controller, which pro- vides real-time, visual views of your data in both tabular and graphic formats. These new water- proof, touch screens provide colorful, at-a-glance monitoring of testing functions without the use of a computer. Operators can see all the data in sev- eral formats at the machine while the test is run- ning. 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 pro- viding report generation capabilities from within Humboldt’s NEXT software or our enhanced test-specific modules. When operated from a networked computer the NEXT software provides robust machine and test control, and report generation. It also allows the ability to control and monitor multiple machines from a single computer. Humboldt Elite Series Data Logger, Analog Provides four individual, 24-bit analog to digital converters with an instrumentation excitation supply of 10 VDC. The analog Logger is ideal for use with instruments, such as pressure transducers, load cells, and strain transducers. It provides data storage for 1000 readings per channel.

Used in conjunction with the SRICOS scour prediction method, the HM-5940 can provide more accurate erodibility measurements and scour predictions than previously obtainable. Applications for its use include: scour at bridges, piping of dams, beach erosion and surface erosion problems. In the case of scour at bridges, the EFA leads to improved accuracy on scour depth predictions, offering several advantages over previous test methods. These advantages include: minimum sample dis- turbance; measurement of erosion rate vs. shear stress; measurement of critical shear stress, and incorporation of the test results from the SRICOS scour prediction method. The HM-5940 erosion function apparatus uses standard 3.0" OD x 2.875: ID (76.2 x 73 mm) Shelby tubes. The SRI- COS method improves the accuracy of pier scour predictions. The HM-4000 EFA is designed to be used in conjunction with the SRICOS method of scour prediction. The SRICOS scour predic- tion method and the HM-5940 erosion function apparatus were developed through research carried out by Jean-Louis Briaud, PHD, PE. and the scour research team at the Texas Trans- portation Institute of the Texas A&M University System. In comparison with the HEC-18 equation (a standard for calculating scour predictions), SRI- COS generally leads to smaller calculated scour depths and compares more favorably to actual measured scour depths. •7" touch screen interface •Records and tabulates test data. •Can store hundreds of tests at a time. •Graphs flow rate vs. time as well as water temperature vs. time •System can automatically fill the water tank using water level sensors. •System can automatically cycle between water sump and water fill during tests to maintain lower water temps. •If hooked up the internet then the machine will auto update with available firmware updates. •Test data can be exported to USB stick for transfer to a PC with “data download software” from the Humboldt website. •Motor can push the sample any specific dis- tance customizable by the user. The EFA uses either of two variants of the SRICOS method: The Extended SRICOS Method: 1)Calculate the maximum depth of scour. 2)Collect soil samples at the site. 3)Test samples in the EFA to obtain the erosion rate vs. the hydraulic shear stress applied. 4)Prepare the velocity hydrograph for the bridge. 5)Use the SRICOS program with 3 & 4 above as input and generate the depth of scour vs. time over the period covered by the chosen hydrograph. The Simple SRICOS Method: 1)Calculate the maximum depth of scour. 2)Collect soil samples at the site. 3)Test samples in the EFA to obtain the erosion rate vs. hydraulic shear stress applied. 4)Calculate the equivalent time for a given design life of the bridge and for the design velocity. 5)Using known equations, calculate the scour depth at the end of the design life.
