7.2.1 Adhesive mounting strip
An adhesive mounting strip is adhered to the flat surface of the aluminum disk. To mount the
sensor, remove the paper from the mounting strip and adhere it to the back of the PV module or
other device. The mounting strip must be adhered to a clean surface for its adhesive to function
properly.
CAUTION:
Do not use epoxy to secure the sensor head to a PV module.
7.2.2 Extreme sealing tape
Use extreme sealing tape for cable strain relief. A yellow label on the cable indicates where the
cable must be secured (
(p. 10)). If the temperature might exceed 70 °C, extreme
sealing tape is required to better secure the sensor to the measurement surface.
To ensure that the sensor disk and cable are adequately fastened to the measurement surface,
use three strips of tape in two places each:
1. For strain relief, place the first strip of tape across the cable just below the yellow heat
shrink (
(p. 10)) and rub the tape surface to remove bubbles.
2. Place the other strips of tape perpendicular and on top of the first strip of tape and rub the
tape surface to remove bubbles. These strips of tape should form an “H” (
10)).
3. To secure the sensor to the module surface, remove the paper from the bottom of the disk
and adhere the disk to the PV module (
Placement on a photovoltaic (PV) module
4. Place a strip of tape across the sensor head, perpendicular to the cable and rub the tape
surface to remove bubbles. Rub as close as possible to the sensor disk.
CAUTION:
Do not place tape over the sensor molding; only place tape on the metal disk portion
of the sensor.
5. Place the two other strips of tape on the ends of the sensor disk, perpendicular to the first
piece of tape and parallel to the cable then rub the tape surface into the module surface.
