Wireline Remote Transmitting Tool (ERTT70)
The Wireline Remote Transmitting Tool (ERTT70) is the downhole telemetry interface for ELIS70 tools. The ERTT70 includes three orthogonal accelerometers, three orthogonal magnetometers, and temperature. It continuously establishes the position of the tool string with respect to depth and magnetic north. It also has some auxiliary function, such as cable head voltage monitor, temperature measurement, downhole tool motor control.
