Cable Transmitter

The cable transmitter has the same general features and capabilities as the other DigiTrak Transmitters but with increased depth range. The dimensions of the cable transmitter are the same as those of the 2- cell DigiTrak Transmitters (DT, DX, and DXP). However, there is also a power/signal cable extending from the rear metal grounding cap. The metal grounding cap must make solid contact with the interior of the housing, which is grounded through the drill. The function of the wire is to provide power to the transmitter and to send the pitch, roll, voltage, and temperature information to the remote display.

The cable transmitter is inserted into the transmitter housing, using the cable extraction/insertion tool, so that the cable extends through the back of the housing. A compression fitting is used to seal the transmitter compartment from drilling fluid/water. Optimal compression fitting characteristics include a washer in the uphole side of the rubber stopper (inside compression fitting) and/or a tapered-interior- diameter shaft to avoid stopper inverting due to drilling fluid pressure. The cable is routed through the interior of the drill pipe; it exits the drill pipe at the drive chuck with another compression fitting or through the mud swivel. As drill rods are added, the wires are connected using butt splices plus heat shrink with hot melt glue. A slip-ring or mud-swivel assembly can be used to enable constant monitoring of the transmitter information. These are not required; however, if one is not used, it will be necessary to disconnect while drilling and reconnect the wires in order to view the transmitter information.

The Cable Transmitter System has the following characteristics:

¾The calibration procedure is a 1-point calibration; 2-point is required if the cable transmitter is in the ground.

¾An input voltage between 12V and 28V DC.

¾The typical power source is one or two 12V DC lead-acid automotive batteries, which may be connected in series for 24V DC. With this 24V DC source, approximately 2000 ft (610 m) can be drilled before recharge.
