The three-component magnetic variation station

The three-component magnetic variation station (MVS) is designed for measuring increments make up the magnetic induction vector field of the Earth (variations) on a network of magnetic observatories. Application area of MVS - terrestrial magnetic, search, predictive, scientific research and special projects. The MVS can be used in conditions of nonperforming or rarely serviced items, as well as in observatory, laboratory and field environments.

Keywords: magnetic observatory, magnetic variation station, magnetometrical converters, quartz magnetic field sensors, magnetic measurements.

Double-channel interferometer for measuring the topography of moving surfaces

System of monitoring and measuring the topography of moving surfaces based on a white light double-channel interferometer is presented. It is shown that using of two channels for synchronous recording of antiphase interferogram dramatically improves the system performance and reduces vibration impact on measurement accuracy. It is experimentally shown that error of moving surface topography measurment can be achieved of less than 1 micrometer.

Keywords: white light interferometry, double-channel interferometer, relief measurement.

The submersible nitrogen cryostat for calibration of temperature sensors with operation range from 180 to 100

The article presents developed installation and an original computer program for incremental calibration of the temperature sensors. This installation provides automatic calibration of the sensors in the temperature range of ?180 to 100 C. The hardware part of the device consists of a cylindrical structure, known as the inverted Dewar, shape and size of which is designed to be placed in the neck of the standard 25-40 liter Dewar flask containing liquid nitrogen. The copper cell, in which the sensors to be calibrated and reference temperature sensors are placed, is located in the lower part of the inverted Dewar in the heating compartment filled with boiling nitrogen vapors. The automation of the installation was carried out with the use of computer measuring system Aksamit 6.25. Software application, which automatically controls the calibration process at a predetermined temperature range, at a predetermined pitch and criterion of the thermostatic status has been developed. The calibration can be performed starting from the minimum predetermined temperature range and vice versa.
The advantages of the designed cryostat are in its compactness, versatility, which allows either calibration of the various kinds of temperature sensors or the temperature dependence determination of the other types of sensors (humidity, strain, pressure, etc.) and the full automation of the process.

Keywords: cryostat, calibration, temperature sensor, automation, software.
