Thermal Ribbons for pipe sensing
Thermal Ribbons make a practical, economical alternative
to traditional immersed sensors for sensing fluid tempera-
tures in pipes or tanks. They mount directly on pipe sur-
faces, so there is no need to tap and drain systems to
install thermowells. If the Thermal-Ribbon is installed cor-
rectly, tests show that the thermal response is as quick and
accurate as traditional invasive sensors. See page 9-7 for
Thermal-Ribbons specially designed for pipe sensing.

THERMAL-
RIBBONS
Thermal-Ribbons lend themselves to a variety of installation
methods. You should avoid repeated bending during the instal-
lation process, and Thermal-Ribbons should not flex in use
unless they are specifically designed to do so. Take care to
secure leadwires so they do not pull against sensor bodies.
Leadwires should be routed along the sensed surface a short
distance so that they do not sink heat away from the sensing
element. Listed below are some standard installation methods.
Pressure sensitive adhesive
PSA (option B in part number) is the simplest mounting
method, but it is restricted to flat surfaces and temperatures
below 177°C (350°F). PSA is usually factory applied to the
mounting surface of the Thermal-Ribbon. To install, just remove
the backing paper and press in place.
#20 stretch tape
High temperature silicone rubber tape for mounting Thermal-
Ribbons to pipes or other cylinders as shown above. It comes
in 1" wide rolls, 6 or 36 feet long.
#6 RTV cement
Room temperature vulcanizing cement for mounting silicone
rubber Thermal-Ribbons to flat or curved surfaces. It is avail-
able in 3 oz. (89 ml) tubes. Contact Minco for other adhesives
usable with Kapton™ or Mylar™ Thermal-Ribbons.
Shrink bands
Minco shrink bands are pre-stretched plastic strips with adhe-
sive at both ends. Use them to mount Thermal-Ribbons to
cylinders. Simply wrap the band around the sensor and cylin-
der, secure the ends, and heat to shrink in place. To order, spec-
ify band width and cylinder diameter.
#21 Polyimide tape
High temperature tape with silicone-based adhesive. Useful for
quick mounting of Thermal-Ribbon or Thermal-Tab sensors to
flat surfaces. Makes a strong but removable bond to most
smooth and clean surfaces. Maximum operating temperature is
150°C. 0.5 inch wide x 108 ft. long roll.
