METHOD FOR DETERMINING THE THERMAL INERTIA INDEX OF TEMPERATURE SENSORS
The invention is intended for use in oceanology and can be used in other fields. The essence of the invention lies in the fact that a transient analysis is used after a step-by-step effect is applied, while two sensors are used together, the first of them with an unknown thermal inertia index and the second model with a known thermal inertia index, a step-by-step temperature effect is applied simultaneously to the inputs of two sensors, a transient temperature difference of two sensors is used to determine the moment the time of the onset of its maximum, the time interval from the beginning of this transition process to the maximum is recorded, the thermal inertia index of the first sensor is determined by the numerical solution of the equation, where ex is the unknown thermal inertia index of the first sensor; e0 is the known thermal inertia index of the second sensor; tm is the time interval from the beginning of the transient temperature difference of the first and second sensors to its maximum. The technical result is an increase in accuracy and simplification of the calibration procedure.
METHOD FOR MEASURING TEMPERATURE, PRESSURE AND DENSITY PROFILES IN A LIQUID
The invention is intended for use in oceanology and can be used in other fields. The essence of the invention lies in the fact that distributed thermoprophilometers are used, containing n conductors modulated by linear sensitivity according to the functions of {<p, (z)}. At the same time, three thermoprophilometers with different temperature (ai) and tensor (βi) sensitivity are used.They are placed in a common soft shell and installed in the medium along the measured profile.
Program for verification of measuring channels and calculation of metrological hydrological characteristics “POVERKA”
The invention relates to the field of measuring technology, namely to contact sensors of electrical conductivity of STD probes, and is intended for measuring the specific electrical conductivity of seawater directly in the medium. The essence of the invention lies in the fact that a U-shaped electrical conductivity sensor includes a measuring zone and a zone used for locking current lines containing two common current electrodes, an additional zone for measuring additional parameters of seawater containing temperature and pressure sensors of seawater having with a marine conductivity sensor water and temperature sensor housing common housing and cover. The invention provides the possibility of placing additional sensors within the total current of seawater and elements of protection against mechanical damage without distorting the current lines and reducing accuracy, as well as without increasing the linear dimensions of the specific conductivity sensor. 4 z.p. f-ly, 2 il.
The “Idronaut” program
The Idronaut program is designed to collect, store and process data from the oceanographic probe Ocean Seven 316 Plus CTD. The program stores the received information in the primary form in the vessel’s database and recalculates the measurements, bringing them to the values for each meter of depth, which allows you to control the quality of measurements directly on board the vessel and promptly process the information: build profiles, sections, maps, calculate time series of measurements, perform calculations of statistical dependencies of the measured parameters. The program calculates the total measurements of the number of stations by sea squares, by year, month and time of day, allows you to export the measurement results in various formats. A distinctive feature of the program is its focus on the average computer user.
