SR05-D2A2 Solar Radiation Sensor： User's Manual Datasheet

SR05 series is the most affordable range of pyranometers meeting ISO 9060 second class requirements. SR05 measures solar radiation received by a plane surface, in W/m², from a 180 ° field of view angle. It is ideal for general solar radiation measurements in (agro-)meteorological networks and PV monitoring. The pyranometer is easy to mount and install, in particular with SR05’s ball levelling mechanism. Various outputs are available, both digital and analogue, for ease of integration. Version SR05-D2A2 offers Modbus over TTL and 4-20 mA output.

SR05 pyranometer mounting and leveling

Optionally SR05 has a unique ball levelling mechanism and tube mount for easy mounting and levelling on a (non-)horizontal surface or tube. As is shown in the images.

Design and Output

SR05 pyranometer employs a thermopile sensor with black coated surface, one dome and an anodised aluminium body with visible bubble level. SR05 has a variety of industry standard outputs, both digital and analogue:

SR05-D1A3: digital sensor with Modbus over RS-485 and analogue 0-1 V output

SR05-D2A2: digital sensor with Modbus over TTL and analogue 4–20 mA output

SR05-A1: analogue sensor with analogue millivolt output

Suggested Use

general solar radiation measurements

(agro-)meteorological networks

PV power plant monitoring

Areas of Application

Meteorology / surface energy flux measurement

Solar energy / PV system performance monitoring
