Class A pyranometer for fast global irradiance monitoring

LPR10

Class A pyranometer for fast global irradiance monitoring from -200…4000 W/m2, with < 0.3 s response, isolated RS485 Modbus-RTU, integrated heater, tilt and diagnostic sensors.

Introduction

Fast, reliable solar radiation data is essential for PV monitoring, meteorology, research and environmental studies. LPR10M0T measures global irradiance on a flat surface, combining direct and diffuse solar radiation with a thermopile sensor classified as Fast Response Spectrally Flat Class A according to ISO 9060:2018.
 
Built-in diagnostics help operators trust the data over time. Internal temperature, relative humidity and pressure sensors monitor operating conditions, while the tilt sensor checks installation stability after commissioning. The integrated heater helps prevent dew and frost, with automatic, always-on or always-off operating modes to balance measurement reliability and power use.
 
Installation and integration are designed for professional networks. Adjustable feet, a bubble level with < 0.2° accuracy and a 5-pole M12 connection support precise setup. The isolated RS485 Modbus-RTU output, DATAsense configuration software and supplied ISO 17025 Accredia calibration certificate make the pyranometer ready for traceable monitoring from day one.

Features

Global irradiance measurement

The pyranometer measures global irradiance on a flat surface, including direct and diffuse solar irradiance.

Thermopile sensor

The thermopile principle provides non-selective spectral response, with optical glass dome and diffuser defining the 285…2850 nm spectral range.

Modbus communication

Isolated RS485 Modbus-RTU output provides irradiance, diagnostics, heating status, operating time and calibration history registers.

Installation monitoring

The integrated tilt sensor measures 0°…180° for long-term monitoring of unwanted installation displacement.

Configuration options

The sensor can be configured with DATAsense software, ASCII proprietary protocol or Modbus Holding Registers for selected parameters.

Maintenance indicators

Operating time counters and diagnostic alarm thresholds can support planning for verification, cleaning or maintenance.
