SR05-D1A3

Digital second class pyranometer with Modbus RS-485 and 0-1 V output

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. Version SR05-D1A3 offers Modbus over RS-485 and 0-1 V output.

  • Industry standard digital outputs: easy implementation and servicing
  • Easy mounting and levelling
  • Pricing: second class pyranometers finally affordable for large networks

Description

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. Version SR05-D1A3 offers Modbus over RS-485 and 0-1 V 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
