GENERAL DESCRIPTION
The OMEGA SA1-RTD Self-Adhesive RTD
(Resistance Temperature Detector) sensor is
designed for fast surface temperature
measurements up to 260°C (500°F)
continuous or short term to 290°C when
cemented into place. For easy installation
(and removal), the sensor has a self-adhesive
backing; no epoxy or cement is required.
These SA1-RTD sensors are manufactured
with 100 ohm Class A or B thin film RTD
elements whose resistance vs. temperature
characteristics conform to the International
Standard IEC 60751 (also known as DIN
Platinum RTDs). The sensing element comes
standard with three #26 AWG stranded nickel
plated copper extension wires that are PFA
insulated and jacketed (can also be ordered
with two or four wires). The RTD element and
extension wires are secured between a
polyimide base tape layer, and a top covering
of high temperature fiberglass tape and
polyimide tape. This construction provides for
easy mounting to most clean and dry
surfaces, and provides good electrical
isolation between the sensor and the
mounting surface.
OPERATING INSTRUCTIONS:
1. Prepare the surface to be measured by
cleaning it of oils and dirt. A general solvent
or alcohol will do. Doing this will allow for
better surface adhesion.
2. Peel the protective tape from the underside
of the sensor (see Figure 1). Please note
that the protective paper is sliced approx 1/4"
from the leading edge of the sensor to help
removal (take care not to get finger oils on
the silicone adhesive or mounting surfaces).
3. Simply press the sensor onto the surface
and rub for maximum adhesion. It is advised
that the leads also be affixed to the mounting
surface to reduce the pull forces on the wires
and provide strain relief to the sensor.
4. Connect the extension wires to a
temperature measuring or controlling
device and you are ready to begin taking
temperature readings.
REUSING THESE SENSORS:
The adhesive backing on the SA1-RTD
sensors was designed for easy removal, may
be removed and re-installed if not damaged
during removal, and adhesive remains viable.
