Gx Time Chart Recorder Application
With the “Gx Time Chart Recorder” application, voltages are logged as a function of time at a fixed location and the voltage data are time-stamped using either the data-logger’s internal clock or the GPS clock (user selectable).
Typically, time-stamped “structure-to-electrolyte” data collected over a period of time are used to examine the impact of stray current on a structure.
Telluric current pick-up (and discharge) from a buried pipeline is an example of stray current affecting a structure. Other examples include current induced by DC railway and DC welding systems.
One of the principal uses of the “Gx Time Chart Recorder” application is to provide data that can be used to correct CIPS data, should correction be required, i.e. should non-steady-state voltages be detected at fixed locations in the vicinity of a pipe section under test.
The “Gx Time Chart Recorder” application can be licensed for use on both the Gx Pipeline Survey Data-logger and the Gx Site Survey Data-logger
