The new DR30, with heater and on-board tilt sensor, offers the highest accuracy and data availability
Welcome to the next level in solar radiation monitoring! Hukseflux introduces the new DR30 pyrheliometer. DR30 is a high-accuracy digital direct (normal incidence) solar radiation sensor. The scientific name of this instrument is pyrheliometer. DR30 complies with the first class specifications of the ISO 9060 standard and the WMO Guide. This next level pyrheliometer has superior window heating that leads to high data availability, and an internal tilt sensor to check tracker performance.
The all-digital DR30-D1 pyrheliometer offers the highest accuracy and highest data availability, featuring window heating at low offsets. At the same heating power, the heating has been improved with a factor 4, at 4 times lower offsets! DR30 also offers on-board tilt and humidity sensors. It is applied in high accuracy measurement of the solar radiation received by a plane surface from a 5 ° full field of view angle. This quantity, expressed in W/m2, is called “direct” solar radiation or DNI (direct normal irradiance). It is necessary to keep the instrument pointed at the sun by using a two-axis tracker. DR30 can be connected directly to commonly used data logging systems. It offers a digital output via Modbus RTU over 2-wire RS-485. The pyrheliometer features a precision ground and polished quartz window, a compact sized collimated tube and a thermopile sensor with black coated surface.
DR30 is used in demanding applications: PV site prospecting, concentrated solar and high-accuracy solar monitoring networks. It is commercially available now.
