PDI - E-Saximeter (E-SAX)
Hammer Performance Analyzer
    Model:PDI E-Saximeter
    Country of Origin:USA
    Use:The E-Sax is a hand held instrument. In its basic configuration the pile inspector observes the driving process and pushes a button for every depth increment as driving progresses.

Details Solution Applications Downloads Order
Handheld instrument registering relevant pile driving parameters, calculating diesel hammer stroke or hammer blows per minute (BPM), for an accurate pile driving log.
  • Counts hammer blows, and equivalent blows per minute for all hammer types; calculates stroke height for diesel hammers
  • Provides a drive log of blow count as a function of depth
  • Results are downloaded from the E-SAX to your computer
  • Optional accessories allow for impact velocity measurements to compute kinetic energy and depth measurements

The E-Saximeter registers all relevant pile driving parameters. It calculates the hammer operating rate in blows per minute and helps the piling inspector create a pile driving log. For single acting, open-end diesel hammers the E-Sax also displays the hammer potential energy and ram stroke. This measurement is important since excessive stroke can cause pile damage.
The E-Sax is a handheld instrument. In its basic configuration, the pile inspector observes the driving process and pushes a button for every depth increment as driving progresses. Several accessories further enhance the functionality of this time-tested sound recognition device including:
  • Proximity switches installed on the driving hammer and a wireless transmission system (transmitter attached to the driving hammer and E-Sax internal transceiver) enable the E-Saximeter to compute the hammer kinetic energy. Kinetic energy may be input to the GRLWEAP pile driving simulation software to fine-tune the driving criteria.
  • depth measurement reel with wireless transmission capabilities eliminates the need for manual depth increment input, automating the entire creation of the driving log.
