One of the best dynamic characteristics of measuring instruments

The optimal dynamic characteristics of measuring instruments is been considered in article. The condition for a minimum duration of the transition process and the condition of the maximum bandwidth of frequencies assume as optimality criterion. In article are given the recommendations and practical information on the calculation of the optimal values of parameters of devices that satisfy these conditions.

Keywords: measuring device, dynamic performance optimization.

Giga ohmmeter

Is given the simplified schematic diagram of giga ohmmeter, the algorithm of its work are described. Limits of the measurement of resistances are from 10 K to tens of G. The distinctive special feature of device is low test voltage on the measuring probes (is not more than 2,0 V). The acting mock-up of device was tested, an error of measurement of the resistances is not more than 0,2 % with a measurement range from 10 kohm to 2,5 giga ohm.

Keywords: the measuring device, measurement of electroresistance, electric measurements.

Management improvement of quality by the automated complex regenerations of the air environment tightly isolated objects

The analysis of results of working out and application of various methods of clearing of the air environment from carbon dioxide is carried out. It is shown that characteristic feature of tightly isolated objects is absence of interaction with environment and application of the special means which are carrying out regeneration of necessary gas structure of the air environment the automated complexes of regeneration of the air environment (ACRE ) is necessary. The technical decision of system of automatic control for ACRE is presented, allowing essentially to raise quality of management of process of regeneration of the air environment.

Keywords: control, the automated complex, regeneration, the air environment, tightly isolated object, adsorber, steam and gas generator.

Investigation of temperature fields of standart radiators

This paper describes a study of blackbody radiators and the tungsten temperature lamps to detect uncertainties associated with the non-isothermal of the surfaces. For example, the results of numerical calculations of the temperature field of copper and gold cells realized by software Elcut 5 and Ansys 11, shows the influence of various factors on the uniformity of the temperature field. The main problem is the calculation of radiation heat transfer elements of crucible with the environment and the furnace cavity, as the dominant component of heat transfer. The results of the temperature field cavity of cell in the phase transitions of copper measured by spectrocomparator are shown. A good agreement between the results of calculated temperature field and the measured data at the optimum initial conditions are obtained. For the temperature lamps obtained values of uncertainties associated with positioning of the optical axis. The comparative results of the experiments are shown.

Keywords: blackbody model, fixed points, radiation heat transfer, temperature field, tungsten ribbon lamp, thermophysical modeling.
