Engineering Physics Annotation << Back Autonomous Measuring Device of Vertical Profi le of Sea Water Temperature Malashenko A.E., Sidorenko A.I., Mayss А.А., Drofa Yu.V., Leonenkov R.V. The paper considers the issues of determining the static and dynamic error of an autonomous measuring device of vertical profi le of temperature of marine environment at depths of up to 100 m. The device in free immersion mode or sampling on board a vessel measures water temperature every 2 meters according to the pressure sensor data. The measured data (water temperature profi le every 2 meters of depth) are stored in the device memory. The features of the algorithm for processing information from a semiconductor temperature sensor are considered. The results of laboratory studies of the inertia of the temperature meter in the range of characteristic temperatures of the marine environment are presented. Keywords: temperature measurement error, marine environment, dynamic measurement errors, static measurement errors, approximation of nonlinear characteristics of a temperature sensor.
