with heating and tilt sensor DR30-D1 is Hukx's most advanced digital sensor for direct (normal incidence) solar radiation. This high-accuracy pyrheliometer complies with Class A specifications set by ISO 9060 and the WMO Guide. It features superior window heating that leads to high data availability and an internal tilt sensor to verify tracker performance. Welcome to the next level in solar radiation monitoring! The all-digital DR30-D1 pyrheliometer offers the highest accuracy and data availability, featuring window heating at low offsets. At the same heating power, the heating has been improved...

Heated for high data availability High data availability is attained by heating the front window, which suppresses dew and frost deposition. The DR30-D1 pyrheliometer is designed for trackermounted operation. It connects directly to commonly used data logging systems and offers a digital output via Modbus RTU over 2-wire RS-485. – low power consumption: DR30-D1 only needs 2 W to keep its window free from dew and frost. Remote sensor diagnostics In addition to solar irradiance, DR30-D1 outputs sensor diagnostics such as: – tilt angle – internal humidity – heater current Remote diagnostics permit...

zenith angle [°] Irradiance [W/m!] steady state offset [W/mz] Figure 7 The offset of DR30-D1 when heating is significantly improved compared to the older DR01, DR02, and DR03 models. DR30-D1 has a 1.5 W heater and produces a negligible offset. The older models had offsets of the order of 2 W/m2 at the same heating levels. In addition, the temperature of DR30-D1's front window is 4 times higher than that of the older models at the same heating power. Figure 8 Comparison of measured data with and without heating on a typical winter morning. The unheated DR30-D1 has dew on its front window, which...
