Academy / SPT Energy
The energy SPT transmitted to the rods by the hammer blow depends on various factors, including: type of hammer, rod length, blow frequency and energy calculation methods.The SPT energy analyser allows the measurement via sensors of this energy at the moment of impact.
The typical configuration of the survey instruments is shown in figure 3. In fact, current norms include this specification (EN ISO 22476, part 3, Table 4).
