4- 2. Field applications
MS-80 is made for accurate irradiance measurements in the field of solar energy and meteorological research. The
MS-80 analog sensor is well suited to be used in traditional meteorological networks where analog sensors are still
common. MS-80S with the Smart interface with multiple outputs is made for the solar energy industry to be used in
different applications. For PV research, plant monitoring and SCADA (Supervisory Control and Data Acquisition)
controlled systems. The MS-80S with digital (Modbus 485 RTU / SDI-12) can be used in a multi sensor network for
onsite monitoring of large PV plants. Digital sensor can be easily configured, With the MS-80S, users can connect
using a standard laptop and ‘Hibi’; a new, custom built programme developed by EKO to give users real-time access
to the internal diagnostics, custom settings, and data on irradiance, humidity, internal temperature and tilt angle
from the sensor. This data can also be acquired when the pyranometer is connected through the datalogger digital
serial communication port. Each pyranometer has it own unique communication address. This way multiple
pyranometers can be connected in a network.
The MS-80S builds on the revolutionary qualities of the original MS-80 by adding a new internal diagnostics system,
giving users remote visibility over body temperature, internal humidity, tilt and roll angle; helping them to ensure
optimum performance without the need for regular physical checks. Coupled with the 5-year recalibration interval,
the internal diagnostic capabilities of the MS-80S makes it an ideal solution for complex networks, hard to reach
locations, and monitoring stations with restricted access.
4- 3. Application to th e standards
MS-80 models are qualified to be used within any application which refers to an international standard according
to:
ISO9060: 2018 Fast response and spectrally flat pyranometer class A (Pyranometer classification)
