New pile integrity tester launched

US-based Pile Dynamics (PD) has launched a new pile integrity tester (PIT).

PD’s new PIT weighs 500g, has a wireless configuration option and includes a USB port. It is available with one (PIT-V) or two (PIT-FV) data acquisition channels. The PIT-FV can be supplied with one or two accelerometers.

PITs perform pulse echo tests and consist of a main unit, an accelerometer and a hammer, which is used to strike the top of the foundation, producing a wave that propagates down the shaft and is reflected back up.

The reflected wave is received by an accelerometer attached to the pile top. The main unit provides the tester with a velocity as a function of time log to reveal compromised foundations.
