Aeron’s Rigel PT1000 module temperature sensor measures surface temperature of PV panels. The
measurement accuracy of the sensor is < ± 1 %. A strong adhesive on the sensor case is used to fix
it firmly to the back of the panel.
The sensor is a high-quality PT1000 standard RTD with its resistance varying with temperature. The
the sensor has an anodized Aluminium casing which protects the thermistor element from outdoor
environment and is thermally conductive to capture the surface temperature accurately.
