Installation, Maintenance and Operation Manual - Tyco Thermal ...

D Chimney effect on large size vertical pipes, best: on the
bottom.
D Accessibility for maintenance purposes, best: at ground
level.
D Impact of other heat sources, sun etc, best: at cold side.
For details please refer to the engineering documentation.
5.3 Sensor placement: limitation device
6
Typically the sensor is being placed on a length of cable,
that is separated from the pipe by means of insulating
material,in order to create an “artificial hotspot”.
The choice of the right location for the limiter sensor
depends on, but is not limited to following aspects:
D Flow direction of the fluid, best location: upstream.
D Impact of heatsinks such as supports etc, best: away from
heatsinks.
D Accessability for maintenance purposes, best: at ground
level.
D Chimney effect on large size vertical pipes, best: at the top.
D Impact of other heat sources, sun etc, best: at hot side of
pipe.
D It is the responsibility of the installer to ensure that these
conditions are met in the most appropriate way.
For details please refer to the engineering documentation.
Thermal insulation and marking
6.1 Pre-insulation checks
D Visually inspect the heating cable and components for correct
installation and possible damage. (See Section 10 if
damaged.)
D Insulation resistance testing (as per Section 8) is strongly
recommended prior to covering the pipe with thermal insulation.
