I. Ambient Temperature sensor

Our ambient temperature sensors come equipped with a stable aluminium housing and a robust
weatherproof cable. Thanks to the use of top quality components the sensors achieve very high
accuracy and are ideal for use in industrial and field (PV module temperature) environments. If required, the sensors can be ordered with an inspection certificate 3.1 as per DIN EN 10204.There is both a back of module temperature
sensor and an ambient temperature sensor. Both models are now available in various signal output types to match your monitoring and data logging needs. Available sensors are: 0-10VDC, 4-20 mA, and RS485 Modbus outputs.

II SILICON IRRADIANCE SENSOR

Measurement of Solar Irradiance
(GHI/TILT/INPLANE) FOR SOLAR PV PLANT

Silicon irradiance sensors (Si sensor) show a cost-effective, but rugged and reliable solution for the measurement of solar irradiance, especially for the monitoring of Photovoltaic (PV) systems. Based on the construction of the sensor element corresponding to a PV module they are ideal as reference for the monitoring of PV systems. Especially the spectral response comparable to PV modules as well as the similar inclination error (incident angle modifier) allow an exact analysis of PV energy yields using Si sensor data.
