1 INTRODUCTION
PYRAsense series pyr nometers me sure the global irradiance on fl t surf ce
(W/m
2
), sum of direct sol r irr di nce nd diffuse irr di nce.
The PYRAsense LPS03 series f lls within the Spectrally Flat Class C pyr nometers
ccording to the ISO 9060:2018 st nd rd nd meets the requirements of the WMO
“Guide to Instruments nd Methods of Observ tion”.
The intern l temper ture, rel tive humidity nd pressure diagnostic sensors llow
keeping the pyr nometer oper ting conditions under control ll the time nd foresee
ny m inten nce intervention in dv nce, thus ensuring lw ys reli ble me sure-
ments.
The integr ted bubble level nd the djust ble feet f cilit te horizont l positioning
during inst ll tion. As option, they c n be equipped with tilt sensor (option T in the
ordering code) which, in ddition to f cilit ting the inst ll tion of the pyr nometer,
llows continuous monitoring of the correct inst ll tion.
The v rious models re distinguished by the type of output v il ble nd by the pres-
ence or bsence of the "tilt" sensor:

The pyr nometers re f ctory c libr ted in ccord nce with the ISO 9847:2023 (Type
A1) st nd rd: ”C libr tion of pyr nometers by comp rison to reference
pyr nometer”. The c libr tion is performed by comp rison with the reference s mple
c libr ted nnu lly t WRC (World R di tion Center).
The DATAsense PC pplic tion softw re, downlo d ble from the Delt OHM website,
llows configuring the sensor (e.g., Modbus p r meters, me suring r nge for the
n log output, etc.), monitor the me surements in re l time, even gr phic lly for the
irr di nce, nd s ve the v lues detected during the connection in file.
