Product Inquiry

Introduction

Reliable solar radiation data starts with a pyranometer that stays accurate in real outdoor conditions. This series measures global irradiance on a flat surface, covering direct and diffuse solar irradiance for environmental studies, research, meteorology and PV monitoring.
 
Measurements are based on a thermopile sensor with a 200…4000 W/m2 measuring range and 283…2800 nm spectral range. Spectrally Flat Class B classification according to ISO 9060:2018 and factory calibration according to ISO 9847:2023 support confident data quality in demanding monitoring networks.
 
Installation and integration stay practical on site. Integrated bubble level and adjustable feet support horizontal positioning, while IP 67 protection, anodized aluminum housing, ASA screen and optical glass dome help the instrument withstand outdoor use. Depending on the model, outputs include RS485 Modbus-RTU, configurable analog signals, 2-wire 4…20 mA or passive mV.

Features

Thermopile measurement principle

The series uses a thermopile sensor with a black matt coated sensitive surface to measure global irradiance on a flat surface in W/m2.

Digital diagnostics

LPS02Mxx models include internal temperature, relative humidity and pressure sensors. Tilt monitoring is available on models with option T.

Configurable analog output

LPS02MAx models provide a configurable analog output with 4…20 mA default, plus 0…20 mA, 0…1 V, 0…5 V or 0…10 V options.

Software configuration

DATAsense PC software supports Modbus parameter setup, analog output range configuration, real-time monitoring and saving measured values to a file.

Installation design

The housing includes an integrated bubble level, adjustable feet and M5 fixing holes. Optional brackets support mast mounting or inclined installation.

Calibration report

Each pyranometer is factory calibrated according to ISO 9847:2023 (Type A1) and supplied with an individual calibration report.
