Module Temperature Sensors
Tm-Pt1000 / Tm-Pt1000-box
Safety Instructions
The installation and assembly of electrical equipment must be carried out by electrically qualified persons.
The sensor may not be used with equipment whose direct or indirect purpose is to prevent death or injury, or whose
operation poses a risk to humans, animals or property.
Warranty and Liability
The sensor is designed for the measurement of a surface temperature. The warranty is for 1 year from the date of the invoice
for the intended use. IMT Technology does not accept any liability for possible losses or damage due to the incorrect usage of
the sensor. Liability for consequential damages is excluded.
Mounting Instructions
The sensor element is mounted by gluing the aluminium block directly to the measurement surface. The surface must be dry,
clean and degreased. Cleaning should NOT be done with glass cleaner, as some glass cleaners contain additives to prevent
soiling after cleaning and these additives also prevent adhesion. Isopropyl Alcohol or Ethanol is recommended for cleaning.
Temperature sensors shall be placed in representative locations to capture the range of variation and allow determination of
an e ective average. For crystalline silicon modules, select the centre of the centre-most cell within the module, or, when the
module is built with even numbers of rows or columns of cells, select one of the cells closest to the centre.
For bifacial modules, rear-side temperature sensors and wiring shall obscure < 10 % of the area of any cell, and wiring should
be routed in between cells when possible.
It is also recommended using an extra fixing with silicone or Sikaflex, particularly for module temperature above 75°C.
The sensor cable needs a cable grip close to the sensor housing.
If mounted outdoors, avoid direct exposure to sunlight and rain to the sensor housing (aluminium block) and sensor case. If
necessary, provide protection from the sun and rain.
The through holes used to fix the sensor to a stable and suitable surface shall be accessible when the housing is opened. The
tightening torque of the case cover is 180 Ncm.
