Module Temperature Sensor (829)
Function
The sensor (829) has been specially developed for measuring
the module temperature of photovoltaic (PV) systems.
A Pt100 measuring resistor is used as measuring element,
which is protected in a body made of seawater-resistant alu-
minium. An optimal heat conduction between body and meas-
uring element is achieved by a special casting compound.
The temperature can be measured in a 4-wire circuit via the
permanently connected cable. This and the shielded cable
make the measurement less sensitive to external interference.
Assembly
To measure the module temperature, the aluminium body of
the sensor with its thermally conductive adhesive surface is
glued to the module from behind:
• If possible, use gloves.
• Clean the location where the module temperature sensor
is to be mounted with heptane or ethanol (degree of purity:
technical).
• Use 2 cloths (lint-free disposable cloths). Dry the cleaned
area with the second cloth.
• After cleaning, check the 2nd cloth for dirt. (The area
must be free of dirt.).
• Remove the protective paper from the adhesive tape. Do
not reach onto the adhesive surface.
• Stick the sensor onto the cleaned surface.
Note: The position of the sensor cannot be corrected after
gluing!
Electrical Connection
The sensor (829) has an integrated 4 cores shielded sensor
cable .
Connect the sensor to the data acquisition system with a
4-wire circuit. Please see the wiring diagram.
(829) Module Temperature Sensor
If the measuring cable is not long enough to connect the sen-
sor to a data acquisition system, a shielded 4-wire exten sion
cable must connected to the measuring cable over a protected
distribution box.
