System Components
The Eclipse TensiTrak system has six main components:
¾ Eclipse TensiTrak unit – A compact unit that contains a battery-powered transmitter with sensors
that continuously measure and transmit the pull force, maximum pull force, downhole mud pres-
sure, temperature, battery life, and depth/position signal. It also updates and saves the maximum
pull force.
¾ Eclipse TensiTrak receiver – An Eclipse receiver with TensiTrak capability.
¾ Eclipse TensiTrak remote display – An Eclipse remote upgraded to have the TensiTrak firmware.
¾ Eclipse TensiTrak software – Provided on CD along with this manual and sample data.
¾ ACTiSYS infrared cable – Connects serial (COM) port on a computer to the infrared (IR) port on
the Eclipse TensiTrak receiver for data transfer.
¾ USB-to-serial adapter – Converts serial connection to USB connection, which is required if your
computer does not have a serial port.
Eclipse TensiTrak Unit
The Eclipse TensiTrak unit contains sensors that continuously measure the pull force, the downhole mud
pressure, and the maximum pull force. The TensiTrak unit also contains a transmitter so it can send this
information to the receiver. It also sends battery life and temperature information. The TensiTrak unit’s
depth and position can be tracked by the receiver to a maximum depth of 60 ft (18.3 m).
The TensiTrak unit can be powered by either three C-cell alkaline batteries or by a DCI SuperCell Lithium
Battery. The difference between these two power options is battery life. The three C-cells will power the
TensiTrak unit for approximately 15 hours; the SuperCell battery will power it for approximately 40 hours.
The TensiTrak unit automatically begins transmitting the pull force, mud pressure, and maximum pull
force data once the power source is installed. It also automatically starts saving the maximum pull force
data internally.
The TensiTrak unit’s dimensions are 5.5 in. (140 mm) in diameter by 19.5 in. (495 mm) in length. It is
installed behind a reamer or hole opener between the swivel and the product. The inner diameter of the
pulling eye is 1.77 in. (4.5 cm). If the diameter of the TensiTrak unit is smaller than that of the reamer and
product, you may want to shroud the TensiTrak unit; be sure that this is done with nonmetallic material.
