Traditionally, pyranometer measurements were accomplished using sensors with an analog voltage output signal. From the pyranometer, this signal would be measured and recorded on a data logger in the field with the sensor. However, in recent years, users have preferred an on-board digital signal transducer built into the pyranometer body. This digital output can be read directly by a Programmable Logic Controller (PLC), Supervisory Control and Data Acquisition (SCADA) system, data logger, or a computer. While many protocols could be used, many user communities have settled on using the serial communication Modbus RTU protocol over RS-485.
For years EKO has been manufacturing and providing pyranometers with built-in transducers, taking the signal from DC voltage to Modbus 485 RTU or DC voltage to 4-20mA current. Recently, EKO developed a new all-in-one sensor Smart signal transducer which allows selecting from 4 types of output in one unit. This new Smart transducer will also have additional features such as internal temperature and humidity sensors and a tilt sensor. These additional internal sensors will help the user to monitor the stability of the irradiance sensors as well as to ensure its proper installation and maintenance practices. Starting Q3 of 2019, pyranometers can be ordered with the basic analog output signal or with this new all-in-one Smart transducer. Following the introduction with pyranometers, EKO will expand the use of this transducer to other sensors and systems as well.
