- Аннотация: One of the main noise-causing factors in precise long-period seismometry is temperature fluctuations of mechanical elements of devices and sensitive sensors, as well as temperature oscillations in their interior space. To reduce such noise level it is possible to apply adaptive filtering of seismic signal based on elements temperature acquisition. However, to date, this way it was not possible to achieve significant results since there were no small systems capable of recording temperature changes with sufficient accuracy. The developed precision small-sized temperature sensors are capable of simultaneously monitoring the temperature at several of the most important points of many seismic device with an accuracy of at least about 0.001 Celsius degrees.
