Portable Falling Weight Deflectometer PRIMA100 - FWD

The new generation of PRIMA 100 portable FWD is a handy instrument for on-site measurement of bearing capacity to minimize risks and optimise quality. The best of our long FWD production experience has been used for the PRIMA 100.

Compared to other kinds of measuring equipment, the investment in a PRIMA 100 FWD equipment enabling high quality data collection is very low and means a tremendous cost reduction as on-site analysis of collected data allows immediate information and printout of reports. Only one person is needed for the work and the equipment can work under very diffi cult conditions like in excavation trenches. Site locations can be captured by means of GPS (Geographic Positioning System), which enable presentation of data in maps or general plans of site.

The data transfer system of the new generation of PRIMA 100 is very flexible and allows for wireless (HF) transfer of data. This enables unique working conditions and only one person is needed for the work. The operator may leave the PC in the car while measuring on site and still have data displayed on a wireless control board while working.

PRIMA 100 is unique for quick in-situ control of unbound base layers, subbases or compacted layers. All you need is a PC with a data evaluation program. All data is stored on PC in ASCII format enabling direct conversion to e.g. Microsoft EXCEL or WORD so that data can be used directly in a report.

PRIMA 100 is powered by four 1.5 volt standard AA batteries and no extra power supply is needed. PRIMA 100 standard model has one centre geophone. Extension to three geophones is possible.
