SPT Hammer Energy Measurement System
标准贯入锤击能量测试系统
Design codes increasingly ask for N60 values, which means measuring what energy actually reaches the rods. This system uses two strain bridges and two ±5000 g accelerometers on a 0.6 m instrumented rod, sampling at up to 100 kHz. It calculates transferred energy by force-velocity integration and shows waveforms live on a rugged tablet.
- Sensors
- 2 strain bridges + 2 piezoelectric accelerometers
- Instrumented rod
- AW or NW rod section, 0.6 m
- Accelerometer range
- ±5000 g
- Sampling rate
- Up to 100 kHz per channel
- Resolution
- 16-bit A/D
