InfraTec LMM-274

Dresden, Germany  —  With the new LMM-274, InfraTec now offers a low-power detector with four channels, so that three gases can be measured simultaneously and a reference channel is also available.

Due to the high sensitivity of more than 90 kV/W, the LMM-274 is ideal for gas analysis in the wavelength range of 8 to 12 micrometers (microns) and can be used to identify alcohol or chlorinated hydrocarbons.

The extremely low power consumption of 40 ?W at 2.7 V particularly suits requirements for the operation of portable infrared gas analyzers.

Due to the very high signal voltage – up to several 100 mV – they can easily be coupled with a microcontroller. Continue reading

FIBER OPTIC TEMPS SOLUTIONS FOR GENERATOR & TRANSFORMER

Sensors immune to RFI & EMI emissions + intrinsically safe

Fotemp1-4 Fiber optic thermometer

Fotemp1-4 Fiber optic thermometer

Dresden, Germany — Due to the growing demand of energy, existing power plants and grids are stretched to their limits.

To ensure operational safety, critical factors such as temperature has to be monitored in generators and transformers.

High power generators are often filled with hydrogen in order to cool effectively. In addition,  the heavily contaminated electromagnetic environment has a high risk for explosions.

Optocon AG in Germany offers a variety of fiber optic temperature measuring devices, fiber optic temperature sensors and accessories for temperature monitoring in oil-filled power transformers.

You can enjoy all the benefits of the fiber optic measurement principle. Continue reading

The article  begins,

SIGNIFICANCE:

“We find that many of the Earth’s climate variables, including surface temperature, outgoing longwave radiation, cooling rates, and frozen surface extent, are sensitive to far-IR surface emissivity, a largely unconstrained, temporally and spatially heterogeneous scaling factor for the blackbody radiation from the surface at wavelengths between 15 ?m and 100 ?m.

“We also describe a previously unidentified mechanism that amplifies high-latitude and high-altitude warming in finding significantly lower values of far-IR emissivity for ocean and desert surfaces than for sea ice and snow.

“This leads to a decrease in surface emission at far-IR wavelengths, reduced cooling to space, and warmer radiative surface temperatures.

“Far-IR emissivity can be measured from spectrally resolved observations, but such measurements have not yet been made.”

Metrology for air temperature

9 December 2014 | NPL | UK

Screen Shot_NPL_LogoTeddington, UK  —  This meeting on Metrology for air temperature, will include presentations on several subjects related to air temperature, covering measurement techniques, calibration, uncertainty evaluation, and applications of air temperature measurement.

It is part  set of one day meetings held jointly by NPL and UKAS, known as “NPL-UKAS Measurement Days.

Air temperature measurements are made in all walks of life. They are particularly important in study of climate and weather, in environmental testing, and wherever any thermal environment needs to be precisely measured and controlled. Continue reading
