scope of application

High strain bearing capacity testing, low strain reflection method testing, dynamic parameter method testing, ground pulsation shear wave testing, Rayleigh wave velocity testing, four channel seismic survey

PDS-PS is a pile foundation dynamic testing instrument launched in 2009 based on the FDP204PS integrated high-resolution floating point dynamic testing instrument. The computer system used in the PDS-PS pile foundation dynamic testing instrument is the Samsung S3C2440 ARM9 with a main frequency of 533MHz, which can smoothly run the Windows CE 5.0 operating system and increase the stability of the instrument. The high brightness semi transparent and semi reflective 7.2-inch widescreen TFT true color LCD screen and touch screen enable the PDS-PS pile foundation dynamic tester to be easily operated and browsed under strong light. High speed data acquisition system and electronic testing system integrated with power supply. It can not only perform data collection work, but also perform data processing and report writing on the instrument. Data can also be transferred to the computer through a USB port for later analysis and processing. This instrument adopts technologies such as preamplifier current servo and fully automatic bridge balance tracking.
