For more than 20 years the PIT has been the go-to instrument for low strain integrity testing of deep foundations. In its simplest configuration, PIT performs pulse echo tests and consists of a main unit, one accelerometer and one hand held hammer. The hammer is used to impact the top of the foundation, producing a wave that propagates down the shaft and reflects back up. The reflected waves are received by an accelerometer which is attached (typically with wax) to the pile top. The main unit provides the testing professional with a velocity as a function of time log that may reveal a compromised foundation element.
As new electronic technologies became available, so did new models of PIT. Some PIT models enable tests where two accelerometers are used, or where the hand held hammer is instrumented with an accelerometer, for more sophisticated integrity analysis (transient response). A few years ago, Pile Dynamics released the PIT-X, a very compact Pile Integrity Tester that weighs only 500 grams and has a wireless configuration option (no cables connecting accelerometers or instrumented hammers to the main unit).
We are writing to you today to let you know about the latest model of PIT. This is a traditional (wired) model.
This new PIT-FV has a large and bright color screen – 21.3 cm (8.4”) and at 1.5 kg, it is quite light. This new PIT has a contemporary look and features a standard USB port for convenient data transfer. It is available with either one or two channels of data acquisition, both traditional (wired). The 2 channel model, known in the industry as PIT-FV, is most often supplied with one accelerometer (provides velocity data through integration) and one instrumented hammer (force data, hence the name PIT-FV). This model may also be used with a non-instrumented hammer and 2 accelerometers, technically making it a “PIT-VV” (some special technical applications require two acceleration inputs).
We are pleased to be able to offer you many choices for your pulse echo testing and transient response integrity testing needs. Whether you prefer an ultra-light model or a larger screen; whether you are partial to the convenience of wireless testing or the comfort of a traditional wired setup; whether your require the analysis capabilities provided by two channels of data acquisition or relish the economy provided by a single channel instrument, Pile Dynamics has a PIT for you.
