Description

DR30-D1 next level digital first class pyrheliometer

DR30 next level digital first class pyrheliometer

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-D1 digital sensor with connector

Heated for high data availability

High data availability is attained by heating of the front window. This suppresses dew and frost deposition.

  • low power consumption: DR30 needs only 2 W to keep its window free from dew and frost

 

DR30-D1 pyrheliometer has superior window heating that leads to high data availability

Remote sensor diagnostics

In addition to solar irradiance, DR30 outputs sensor diagnostics such as:

  • tilt angle
  • internal humidity
  • heater current

Remote diagnostics permits real-time status monitoring, reducing the need for (un)scheduled field inspections.

Suggested use

  • solar energy surveys
  • solar resource assesments
  • meteorological networks
  • sites with dew and frost problems
