SPT Energy Calibration

The energy delivered to the SPT sampler is always some percentage less than the theoretical maximum.

In order to more correctly interpret the SPT blow counts, it is essential to measure energy and correct the SPT blow counts for the mechanical system's efficiency. ConeTec's SPT Energy Calibrator allows energy to be recorded in two ways. The calibrator is capable of measuring force² vs time and acceleration vs time. From each of these data sets two independent estimates of the overall SPT system efficiency can be computed.
