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.
