Soluzione Solare Temmeter TM3 PT100 Class A Module Temperature Sensor
The Temmeter TM3 with PT100 probe by Soluzione Solare is the sensor that measures the cell temperature of the PV module, a figure that is essential for calculating the plant's Performance Ratio according to IEC 61724-1 and for distinguishing a drop in yield caused by overheating from an actual fault.
It is applied to the back of the PV module using a stainless steel fixing system with an aluminium bracket and an adjustable contact spring, without adhesives, so as to guarantee thermal adhesion and allow removal without damaging the backsheet. The sensing element is a class A PT100 in AISI 316 steel with a 2 m shielded cable; the output is of the resistive analogue type and is converted into a Modbus digital signal by the data logger or by the Sunmeter converter/irradiance sensor the device is to be paired with.
Key features
Class A PT100 probePT100 element compliant with and better than class B of IEC 60751, with an accuracy of ±0.6 °C over the whole scale.
Extended measuring rangeIt measures from −50 °C to +200 °C, well beyond the actual temperature range of a PV module.
Fast responseResponse time of less than 10 seconds for temperature variations of at least 2 °C.
Mounting without adhesivesThe aluminium bracket and stainless steel spring guarantee contact on the back of the module without adhesives, with the option of removal.
AISI 316 steel constructionSheath and probe in AISI 316 stainless steel with a 2 m steel-clad cable, resistant to UV, moisture and aggressive environments.
Flexible connectionAvailable with a 2-pin IP67 M8 connector or with three free conductors (white-red) for a terminal block.
