Accuracy, Precision and Noise of Gas Sensors – Definitions
Introduction „Accuracy“ is one of the most important quality criteria of a gas sensor. But sometimes „precision“ rather than „accuracy“ is required for sensors. And unfortunately, in practice, high measurement accuracy often has to be bought at the price of reduced precision and vice versa. Data sheets often fail to declare what is actually meant by…
Difference between gas sensor and gas analyser
Summary For the GasAnalzer V3 platform we use the term ‚Gas Analyser‘. This is because various sensor data are measured and the data streams analysed together, which is the definition of a ‚gas analyser‘. Are fastLine gas sensors „gas sensors“ or „gas analyzers“? The difference between a gas sensor and a gas analyser is becoming…
New Measurement Platform V3
New platform V3 „fastLine“ for gas sensors released The new platform V3 featuring the optical infrared gas measurement technique is released after intensive testing for dual-channel, dual-beam configuration. The platform can be easily adapted for different gases with different concentrations to be measured. Two or more gases can be measured in two measuring channels. Extrem…
NDIR Technology fastLine sensors
Measurement principle NDIR stands for None-Diffractive Infrared and is a photometric, non-invasive method of measuring gas concentrations. NDIR technology measures the absorption of infrared (IR) light by a gas in a specific optical spectrum. It make use of the physical property of spectral absorption of the gas: Each gas only absorbs light in certain spectral…
