New standard digital thermometer LTA. The study of accuracy and stability during operation

TERMEX Ltd. has developed a new compact electronic thermometer LTA that can be used as a standard instrument for calibrating industrial temperature instruments, as well as an accurate laboratory thermometer that can replace most of the mercury-glass thermometers used in the oil and gas industry. This article focuses on the study of the metrological characteristics of LTA, in particular the instability of its characteristics during the time interval between calibrations. According to the results of the tests conducted in D.I. Mendeleyev Institute for Metrology, the thermometer meets the requirements on accuracy and stability for the 3-level standards.

Keywords: standard thermometer, electronic thermometer, digital thermometer, calibration of temperature instruments, instability of thermometer.

Information-measuring systems. assessment of potential risk from flooding of the railway track

The necessity of development of the system of monitoring of the railway track and the adjacent territory with the use of geographic information systems is substantiated. Estimates for the formation of an integrated assessment of the state of the railway track and the surrounding area are given. The assessment of risk of flooding of the territory adjacent to the railway at the stage of design of the railway track is proved. There are four zones of possible flooding with different functional purposes. Calculations of the risk of flooding of the territory are made on the example of Tosnensky district of the Leningrad region.

Keywords: geographic information systems, risk, emergency, flooding, linear section, geotaxon, area analysis, estimation, traffic safety, railway track.

The method of controlling the profile of the formed silicon MEMS structures

In the technology of manufacturing microelectromechanical systems (MEMS), it remains difficult to accurately control the etching time required to obtain a given profile of structures due to the impossibility of its visual evaluation during the formation, as well as the impossibility of measuring the resulting profile with measuring devices such as dial gauges and profilometers. In this regard, the issue of controlling the geometry of the formed structures is an important task in the technology of silicon MEMS devices.

Keywords: anisotropic silicon etching, complex-shaped profile, silicon microstructure, etching control.
