The SP-510 is an upward-looking thermopile pyranometer with an analog output of 0 to 114 mV. The sensor incorporates a blackbody thermopile detector and acrylic diffuser with a rugged, self-cleaning sensor housing design. Typical applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks. Sensors are also used to optimize photovoltaic systems.
These sensors can also be coupled with our downward facing pyranometer to form an albedometer. For this application, we recommend using our AL-130 Albedometer mounting bracket. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
