A. TT1100-OHP is available in a variety of pre-cut and terminated
lengths. Each cable has a female plastic connector on one
end and a male plastic connector on the opposite end. Cable
sections plug together like extension cords.
B. (Optional) A branch connector (TT-MBC-PC) is used to connect
and branch “T” lines. The branch connector has one male
connector and two female connectors. For mapping purposes,
the cable connected to the center leg of the branch connector
will be counted first, then the distance measurements will
continue from the second female connector and continue along
the rest of the system. A dead band of 15 ft (5 m) is inserted
at the beginning and end of each branch to avoid any location
ambiguity.
C. (Optional) It is permissible to have TT-MBCs installed on
branches as needed to fully trace a pipe system.
D. Install an end termination (TT-MET-PC) at the end of the main
line and each branch line. (Note: A good check on the system
design and bill of materials is that the total number of end
terminations installed in the system should equal the number
of branch connectors plus one)
E. (Optional) Install jumper cables (TT-MJC-xxx-PC) as needed to
connect sensing cable sections if they are spatially separated.
Jumper cable is available in various pre-cut and terminated
lengths and is also available in bulk form for long distance runs
between the sensor cable and the instrumentation point.
F. Install a leader cable (TT-MLC-PC) between the sensor cable
and the monitoring instrument. The factory standard length
of leader cable is 12 ft (4 m). It has a female plastic connector
on one end and four tinned leads on the opposite end for
connection at the instrument’s sensor cable terminal block. In
some installations the distance between the instrument and the
start of the sensor cable run will be much greater than 12 feet.
In those cases a simple solution is to purchase a jumper cable
of sufficient length, then cut off and discard the male connector
and any extra cable. Bulk jumper cable and connector kits are
also available for lengths that exceed the longest available pre-
cut jumper cable.
G. Use tie-wraps to neatly coil and secure any excess sensor
cable, jumper cable, branch connectors, etc.
