Location
– as indicated in the system design documentation
– not on valves, flanges, supports, pumps or other heat sinks
– at the top of the pipe for thermally sensitive pipe contents (A)
– on lower quadrant of pipe 90° for single heating cable (B)
– on lower quadrant of pipe centrally between the heating cables if they
are two or more (C)
Attachment of the sensor
–fix sensor firmly on surface with adequate fixing tape (same tape as
used to fix heater to the pipe) in two places (D)
–fix sensor parallel to pipe (D)
– route sensor cable and eventual extension cable to avoid damage in use.
Fix to pipe with adequate tape where appropriate.
Warning: Do not install sensor at ambient temperatures below –20°C. Do not
bend sensor (last 50 mm), keep it straight under all circumstances. Min.
bending radius for sensor cable: 10 mm.
