Strain Transducers and Acclerometers manufactured by pile Dynamics collect the essential data for use with Pile Driving Analyzer(PDA) and SPT Analyzer.

Reliable results start with reliable measurements: The axially accurate strain and accleration signals collected at high microstrain and "g" Levels are converted by the PDA(or the SPT Analyzer) to force and velocity records. These records are then used in evaluations of foundation capacity, foundation integrity, hammer efficiency and pile driving stresses.

Accuracy matters, but so does convenience.PDI sensors are fast and simple to install and remove.With proper care, both accelerometers and strain transducers have a long useful life.
