Some questions of modernization of culonometric instruments for measuring humidity of gases and liquids

In this paper, we consider the issues of ongoing modernization of devices using a coulometric electrolytic cell for gas analysis. In particular, directions are considered, including the use of auxiliary power sources, the use of additional temperature sensors and cell heaters. The possibilities of automatically setting the flow rate of the analyzed gas through the measuring cell and expanding the measurement range are considered.

Keywords: hygrometer, gas analyzer, moisture meter, coulometric electrolytic cell, modernization of devices.

Processes and metadata as a basis of technical documentation management system

The paper describes effective processes and metadata as an example of practical implementation in the PJSC INEUM I.S. Brook technical documentation management system (TDMS). The considered data in this system belongs to the next types: design, software, technological or other auxiliary documentation. Metadata with links to the storage of technical documentation are introduced as the results of project, production and intellectual activity. The introduction of an original metadata classification for technical documentation makes TDMS an important part of a perspective enterprise management system.

Keywords: technical documentation management system, documentation control process, metadata classification, storage, archive, data navigation.

Binary Balanced DC ridge

The article is devoted to the balanced bridge proposed by the author, called binary. The bridge contains two 2-terminal legs and two adjacent four-terminal legs. The free current leads of the 4-terminal legs are connected by a jumper, and the free potential current leads are connected to the indicator one-by-one the bridge has two equilibrium conditions for a single potential lead and for two potential leads, respectively. Binary balanced bridge allows to measure the resistance of 4-terminal, low-resistance resistors. The task of measuring the resistance of 4-terminal resistors with a single balanced bridge is also considered.

Keywords: Wheatstone bridge, binary balanced bridge, indicator, bridge balance, bridge node, bridge terminal, bridge leg, 2-terminal, 4-terminal, resistor, current lead, potential lead, jumper.

Research and development of a technology of manufacturing of quartz pressure sensor for use in hydrodynamical study in the production of oil and gas

During the research and development of technology of manufacturing of a quartz pressure sensor, the optimal combination of topology of electrode coatings, material and thickness of the electrodes were obtained. The firm conclusion was made that usage of silver electrode or gold electrode permits to decrease the unwanted resonances for more than 5 dB comparative to the main resonance in the frequency range ± 500 KHz of the nominal frequency. The thickness of the round gold electrode should be 25 microns with a diameter of 4.5 mm, the thickness of the round silver electrode should be 60 microns with a diameter of 4.5 mm. This research allows us to develop more efficient and cost-effective pressure sensor in comparison with another existing commercially available analogues.

Keywords: submersible telemetry, quartz pressure sensor, spectral characteristic, electrode.

On the study for the intrinsic error distribution of Metran-150 pressure sensors

For modern measuring instruments, such a parameter as the calibration interval is extremely important. The procedure for its reasonable adjustment (for the purpose of increasing) begins with determining of the distribution law for main metrological characteristics. The paper analyzes two verifications results of six models for Metran-150 pressure sensors, when the intrinsic error values were determined. By means of the Grubbs criterion outliers are excluded from original samples. Then the Pierson χ2-test is used for the normal distribution testing of the pressure sensors intrinsic error. The presented results can be used to justify the calibration interval of Metran-150 pressure sensors.

Keywords: pressure sensor, verification procedure, metrological characteristics, intrinsic error, distribution law, hypothesis testing, consent criterion.
