PYRAsense series pyranometers measure the global irradiance on a flat surface (W/m2), sum of direct solar irradiance and diffuse irradiance.
The PYRAsense LPS10 series falls within the Spectrally Flat Class A pyranometers according to the ISO 9060:2018 standard and meets the requirements of the WMO “Guide to Instruments and Methods of Observation”.
The internal temperature, relative humidity and pressure diagnostic sensors allow keeping the pyranometer operating conditions under control all the time and foresee any maintenance intervention in advance, thus ensuring always reliable measurements.
The integrated bubble level and the adjustable feet facilitate horizontal positioning during installation. As option, they can be equipped with a tilt sensor (option T in the ordering code) which, in addition to facilitating the installation of the pyranometer, allows continuous monitoring of the correct installation. The various models are distinguished by the type of output available and by the presence or absence of the “tilt” sensor:
The irradiance range for the analog output is user configurable (default, 0…2000 W/m2). The pyranometers are factory calibrated in accordance with the ISO 9847:2023 (Type A1) standard: ”Calibration of pyranometers by comparison to a reference pyranometer”. The calibration is performed by comparison with the reference sample calibrated annually at WRC (World Radiation Center).
The DATAsense PC application software, downloadable from the Delta OHM website, allows configuring the sensor (e.g., Modbus parameters, measuring range for the analog output, etc.), monitor the measurements in real time, even graphically for the irradiance, and save the values detected during the connection in a file.
