Mounting and Leveling the SR05 Pyranometer
The SR05 has an optional ball leveling mechanism and a unique pipe holder for easy mounting and leveling on a (non)horizontal surface or pipe.
Design and Performance
The SR05 pyranometer employs a thermopile sensor with a black coated surface, an anodized aluminum dome and body with visible bubble level. The SR05 has a variety of industry standard outputs, both digital and analog:
SR05-D1A3: Digital sensor with Modbus over RS-485 and 0-1 V analog output
SR05-D2A2: Digital sensor with Modbus over TTL and 4-20 mA analog output
SR05-A1: Analog sensor with millivolt analog output
Suggested Use
general solar radiation measurements
(agro)meteorological networks
photovoltaic power plant monitoring
