Spt Analyzer

Clients can avail from us SPT Analyzer which measures the energy transferred into an instrumented SPT rod. This permits the adjustment of the measured N-value to the normalized N60 for standard 60% energy transfer into the rods. Compensating for widely variable efficiencies from different SPT rigs and hammer types improves the reliability of soil strength estimates used in geotechnical designs.

This instrument includes a subassembly of an SPT rod that is instrumented with two strain gage bridges and two piezoresistive accelerometers . These sensors obtain the force and velocity signals necessary for the calculation of transferred energy and transfer them to the SPT Analyzer. The equipment is light and small, and operated by a high contrast touch screen that doubles as a keyboard. The SPT Analyzer includes the PDA Software Suite for data analysis.
