SP-522-SS Modbus Digital Output Thermopile Pyranometer

$433.00

The SP-522-SS is an upward-looking thermopile pyranometer with a digital signal using Modbus RTU protocol over RS-232 or RS-485. The sensor incorporates a blackbody thermopile detector and acrylic diffuser with a rugged, self-cleaning sensor housing design, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. Typical applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks. Sensors are also used to optimize photovoltaic systems. Sensor includes IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement for maintenance and recalibration.
