DOTX-45 Dissolved Oxygen System Part 5 – Sensor Assembly
DOTX-45 22 -
Cord-grips used for sealing the cable should be snugly tightened after electrical
connections have been made to prevent moisture incursion. When stripping
cables, leave adequate length for connections in the transmitter enclosure as
shown below. The standard 25 ft. sensor cable normally supplied with the
system is already stripped and ready for wiring. This cable can be cut to a
shorter length if desired to remove extra cable in a given installation. Do not cut
the cable so short as to make installation and removal of the sensor difficult.

Figure 4-5 Sensor Cable Preparation
Once inside the enclosure, the individual colored sensor cable leads can be
connected directly to the SENSOR connection terminals by matching the wire
colors. On older systems, there may exist a YELLOW wire label on the sensor
terminal strip rather than the wire color ORANGE or BROWN, which are used
now. If your system has a YELLOW label, simply connect orange/brown from the
sensor to that point.
