Irradiance Sensor, Photovoltaic Pyranometer, and Reference Cell: Three Names for the Same Device
In the solar energy industry, it’s common to come across different terms that all seem to describe the same thing. Three such terms are irradiance sensor, photovoltaic pyranometer, and reference cell. While they may sound like different devices, they all refer to the same basic concept: a sensor that measures the amount of sunlight, or […]
Find Out How to connect a sensor with 4-20 milliamps output to a Datalogger/PLC-Original Publish Date: 25 JUL 2022
HOW TO CONNECT A SENSOR WITH 4-20 MILLIAMPS OUTPUT TO A DATALOGGER/PLC 4-20mA output sensors are widespread in the world. This is because the output in ‘current loop’ is the most robust and reliable kind of analogical output. When signal precision is needed, or datalogger-to-sensor distances are over 18m, or in case of electromagnetic disturbances, it’s […]

Calibration of thermopile and photovoltaic pyranometers-Original Publish Date: JUL 2022
Until recently, calibration was done by taking the classic thermopile pyranometer as reference, because we, the testers, had only that tool as a reference. Yes, even we calibrated our primary sensors by comparison with a pyranometer, albeit the best one on the market: a Kipp & Zonen Secondary Standard. But, from months of comparative surveys, […]
Irradiance Sensors vs Pyranometers When Monitoring the Performance of Solar Plants and Solar Energy- Original Publish Date: 25 JUL 2022
When monitoring the performance of solar plants and solar energy, is it better using a silicon irradiance sensor or a pyranometer? When deciding between irradiance sensors and pyranometers, it is better to use an irradiance sensor (or silicon cell irradiation sensor) for the following reasons. Obviously, pyranometers have some advantages. In the downloadable PDF below, each of […]
What is an Anemometer?
Anemometers are instruments that measure wind speed. Users can employ it in different installations, like for example for the management and monitoring of wind farms, weather stations, photovoltaic plants, ski lift, highways, viaducts, high routes, airports. In most applications, users equip anemometer with anti-icing system. TYPES OF ANEMOMETERS Based on the operating principle they are divided […]

The infographic also has scope in the studies of plant and weed growth, solar farm management and meteorology. Use this infographic on your […]
How do thermopile pyranometers work?
The physics behind the thermopile pyranometer Solar radiation can be measured according to the Seebeck effect. This thermopile effect is part of a physical phenomenon called thermoelectric effect, in which the temperature difference between two dissimilar electrical conductors produces a voltage difference. The potential difference between the two conductors kept at different temperatures is defined as the […]
Calibration vs. Adjustment, Accuracy vs. Precision: What’s the Difference?
Calibration and adjustment are two similar processes that are often confused and wrongly used interchangeably. This article aims to clear up the differences. The difference between Calibration and Adjustment The National Physics Laboratory clearly explains the key differences between CALIBRATION and ADJUSTMENT: The procedure is: Metrologically speaking, the International Vocabulary of Metrology, V.I.M ed.3, gives […]
