A versatile thermoelectric temperature controller with 10 mK reproducibility and 100 mK absolute accuracy.

چکیده
We describe a general-purpose thermoelectric temperature controller with 1 mK stability, 10 mK reproducibility, and 100 mK absolute accuracy near room temperature. The controller design is relatively simple and could be readily modified for use in different experimental circumstances. We also describe a time-domain numerical model that allows one to characterize the stability and transient behavior of the system being controlled, even in the presence of elements with highly nonlinear responses.

Comment on "A versatile thermoelectric temperature controller with 10 mK reproducibility and 100 mK absolute accuracy" [Rev. Sci. Instrum. 80, 126107 (2009)].
Libbrecht and Libbrecht recently described a thermoelectric temperature controller for which they claimed an absolute accuracy of 100 mK. They did not specify the heat-dissipation coefficient for their thermistor temperature sensor-which would dissipate more power than is usual in such circuits- nor make any allowance for self-heating in the thermistor. Self-heating can be expected to have intr...
متن کاملUsing AIRS and IASI data to evaluate absolute radiometric accuracy and stability for climate applications
The creation of multi-decadal data sets for climate research requires better than 100 mK absolute calibration accuracy for the full range of spectral temperatures encountered under global conditions. Validation that this accuracy is achieved by the operational hyperspectral sounders from polar orbit is facilitated by comparing data from two instruments. Extreme radiometric calibration stability...
متن کاملThermoelectric power in the quantum-Hall regime at very low temperatures
We have measured the thermoelectric power (TEP) of high mobility 2DEGs in the integer and fractional quantum Hall regime down to 100 mK. At low temperatures, fluctuation-like structures in the TEP are observed. Below 160 mK the TEP diverges around the filling factor v = ~ where the resistivity enters the insulating phase. The temperature dependence of the TEP at filling factors v = 12 and 1⁄4 r...
متن کاملLoad Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator
The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
متن کاملLong-Term Trend Analysis of Climate and Hydrological Series using Removal of the Autocorrelation Statistical Methods in the Eastern Gorganrood Basin, Golestan Province
Given the importance of climate change issue, consideration of the climate and hydrological data trend has become very important. This study aimed to evaluate the effectiveness of different methods to remove the effect of autocorrelation in assessing the trend of parameters such as temperature, precipitation and discharge of the Eastern Gorganrood Basin, Golestan Province. For this purpose, in ...
