SR05 SERIES

Spectrally flat Class C (Second class) pyranometers with various outputs
SR05 series is the most affordable range of pyranometers meeting ISO 9060 requirements. They are ideal for
general solar radiation measurements in (agro-)meteorological networks and PV monitoring systems. SR05’s
are easy to mount and install. Various outputs are available, both digital and analogue, for ease of integration.

Introduction
SR05 series is an economical range of ISO 9060
class C pyranometers for measurement of solarradiation received by a plane surface, in W/m2,
from a 180 o field of view angle. Different
configurations are available, depending on its
mounting and the output needed. The combinationof easy installation and its cost makes SR05 ideal
for installation in (agro-) meteorology networks
and PV power plant monitoring.

Benefits•••

industry standard digital and analogue outputs:
easy implementation and servicing
easy mounting and levelling
pricing: Class C pyranometers finally affordable
for large networks

Suggested use

SR05 series specifications

SR05 pyranometers employ a thermopile sensor
with black coated surface, one dome and an
anodised aluminium body with visible bubble
level. Optionally the sensor has a unique balllevelling mechanism and tube mount, for easy
installation. SR05 has a variety of industry
standard outputs, both digital and analogue:
SR05-D1A3 offers Modbus over RS-485 and 0-1 Voutput, SR05-D2A2 offers Modbus over TTL and4-20 mA current loop output. Version SR05-A1
offers a conventional analogue millivolt output.
