Description Specifications Documents Accessories Video

The Senseca LPS02 Series consists of pyranometers for measuring global solar irradiance on a flat surface, including both the direct and diffuse components of solar radiation. The instruments are suitable for meteorological observations, environmental monitoring, scientific research, and photovoltaic system monitoring.

The series uses a thermopile sensor with a black matt coated sensitive surface and operates over a measuring range of 200–4000 W/m² with a spectral range of 283–2800 nm. The pyranometers are classified as Spectrally Flat Class B according to ISO 9060:2018.

Each instrument is supplied factory calibrated according to ISO 9847:2023, Type A1, together with an individual calibration report, supporting measurement reliability and traceability.

The digital LPS02Mxx models include internal sensors for temperature, relative humidity, and pressure, allowing monitoring of the instrument’s operating conditions. Models with option T also provide tilt monitoring.

Depending on the model, the following output options are available:

RS485 Modbus RTU;
configurable analog output 4–20 mA, 0–20 mA, 0–1 V, 0–5 V, or 0–10 V;
2-wire 4–20 mA current loop;
passive mV output.

Using the DATAsense PC software, users can configure Modbus parameters and the analog output range, monitor measurements in real time, and save measured values to a file.

The housing is designed for outdoor use and provides IP67 protection. It is made of anodized aluminium, with an ASA protection screen and an optical glass dome. The integrated bubble level, adjustable feet, and M5 fixing holes support accurate horizontal positioning, while optional brackets allow mast mounting or inclined installation.
