Photovoltaic Glass in the Reference Cell Sensors for PV Monitoring

One of the key features of the Sunmeter PRO (Reference Cell Sensor) is the integration of photovoltaic-grade microprismatic glass, the same type of glass used in commercial photovoltaic modules. Unlike conventional Si_irradiance sensors that use flat, high-transparency glass, Soluzione Solare integrates photovoltaic-grade microprismatic glass to better replicate the optical behavior of PV modules. The Sunmeter […]

Find Out How to connect a sensor with 4-20 milliamps output to a Datalogger/PLC

4-20mA output sensors are widespread in the world. This is because the output in ‘current loop’ is the most robust and reliable kind of analogical output. When signal precision is needed, or datalogger-to-sensor distances are over 18m, or in case of electromagnetic disturbances, it’s necessary to use a sensor with output in current loop. On the […]
