High humidity creates serious problems for PV sensors, from moisture building up inside and causing short circuits to corrosion that damages sensitive parts, not to mention electrical noise that leads to unreliable measurements. In regions with persistently humid conditions—like Southeast Asia, Central America, and tropical coastal areas—these issues can undermine the lo...
Accurate measurement of solar irradiance is essential for evaluating the performance and efficiency of photovoltaic (PV) systems. Two primary sensor types used in the solar industry for this purpose are thermopile pyranometers and PV reference cells. While both serve to measure solar irradiance, they operate based on different principles and are suited for different appl...
When setting up a PV system, it’s common to wonder why sensors can’t just connect directly to the inverter. The answer lies in function: inverters focus on energy conversion and aren’t built to handle sensor protocols like Modbus RTU or 4–20 mA. That’s why dataloggers are essential—they act as translators and data hubs, collecting and organizing information from all sens...
Temperature-compensated irradiance plays a critical role in ensuring the accuracy of solar power plant monitoring. Even when solar irradiance remains constant, energy output from PV modules can vary depending on temperature. This is because not all incoming solar radiation is converted into electricity—some turns into heat, affecting sensor readings. Reference cell–based...
Operating photovoltaic sensors in regions with extreme temperatures—such as deserts or sun-drenched open fields—comes with a range of technical challenges. Prolonged exposure to heat can lead to electronic drift, signal degradation, thermal expansion, and faster material aging, all of which compromise the accuracy and lifespan of monitoring systems. SEVEN’s sensors are s...
Vibration Sensitive Assets People that owns vibration sensitive assets have ongoing concerns about the potential detrimental impact of surrounding construction work, road or railways traffic. Vibration and/or dust sensitive assets typically include museums, works of art, ancient buildings or facilities equipped with very accurate manufacturing, measurement or inspection...
Calibration of the relative humidity at 9 points in the climatic chamber With the ALMEMO® 710 data logger, a digital psychrometer and 8 temperature sensors, all relevant measured variables are recorded in the climatic chamber. The climatic chamber can be conveniently calibrated on site, as the relative humidity of the 9 points is calculated in the ALMEMO® measuring devi...
Since the earliest developments 150 years ago, advances in light sources, optics, and data processing have firmly established interferometry as an indispensable tool for measurement of distance, displacement, and angle. While it can be sensibly argued that ever-increasing demands on precision have driven advances in interferometric positioning, here we follow the path to...

Many of the same issues keep coming up, in one form or another. So, we have decided to put together a whitepaper that addresses the most common requests for information and explanation. This is particularly topical because there is a lot of confusion resulting from recent changes in key international standards. The whitepaper starts by explaining what is meant by sol...
The Jablonski diagram is widely used in fluorescence spectroscopy to illustrate the excited states of a molecule and the radiative and non-radiative transitions that can occur between them.
Time-correlated single-photon counting (TCSPC) is a well established and common technique for fluorescence lifetime measurements, it is also becoming increasingly important for photon migration measurements, optical time domain reflectometry measurements and time of flight measurements.
The terms; luminescence, photoluminescence, fluorescence and phosphorescence are routinely used in research papers to describe the emission of light from a sample. In this article we answer the question, “What is the Difference between Luminescence, Photoluminescence, Fluorescence, and Phosphorescence”.
