SDI-12 pyranometer CS320

thermopile

The CS320 is a digital thermopile pyranometer that measures broad-spectrum short-wave radiation and communicates over the simple SDI-12 protocol to the data logger. This sensor design eliminates measurement error and programming errors that can adversely affect data quality. This pyranometer has been designed to improve the global solar radiation measurement significantly (even under cloudy conditions) without adding substantial cost. The CS320 is suitable for applications ranging from environmental research to agriculture to large mesoscale weather networks (mesonets). The CS320 is manufactured using a high-grade anodized aluminum body and IP68-rated 316 stainless-steel M8 connector (marine grade). The CS320 sensor is heated (on/off switchable under user control) and allows continuous operation in changing environmental conditions. The pyranometer's calibration data is stored on the sensor. Benefits and Features - Thermopile sensor eliminates spectral errors associated with silicon-cell pyranometers - Much lower price point than other thermopile sensors - On-board sensor automatically detects if the CS320 is level for installation, diagnostics, and remote troubleshooting - Designed for long-term stability and deployment - Dome-shape sensor head allows dew and rain runoff - Internal heater to reduce errors from dew, frost, rain, and snow - SDI-12 digital output - Detachable waterproof connector from sensor head for fast, easy servicing - Calibration data stored on sensor The CS320 combines a blackbody thermopile detector with an acrylic diffuser.
