Software
Gap Transmitter Calculator
The Gap Transmitter Calculator (GapTxCalc) is a utility tool designed by Gap GeoPak to model the performance of the Gap GeoPak high current transmitters for various loop configurations. It has proven to be invaluable for optimising loop design and wire selection. It also remains a useful reference when selecting safe operating parameters by providing improved awareness of the current carrying limitations of various wire sizes as well as relevant voltage considerations.
