POSITIONING THE SENSOR
Position the RTD sensor in the lower quadrant of the pipe as shown
in the diagram. Place the RTD sensor at least 3 feet (1 m) from
pipe supports, valves, or other heat sinks. Tape the RTD firmly to
thepipewithAT-180aluminumtape,makingsurethereisnoair
space between the RTD and the pipe. Do not use the same piece of
AT-180 tape to overlap the RTD and heat-trace cable.

INSTALLATION WITH HEATING CABLE
Electrical Wiring Guidelines:
Mostelectricalcodes(suchasNEC725.15)permitClass1circuits
to occupy the same cable, enclosure, or raceway without regard
towhethertheindividualcircuitsarealternatingcurrentordirect
current,providingallconductorsareinsulatedforthemaximum
voltageofanyconductorsinthecable,enclosureorraceway.
