dc.description.abstractotherCalorimetric methods for ozone concentration measuring can be used to measure ozone concentration at the outlet of the ozone generator in the working zone and in the ozone residue products. However, their distribution is restrained by the lack of the appropriate sensors, which makes their development sufficiently relevant. The calorimetric measurement method is based on the fact that, when ozone is destructed, its enthalpy has a value of 144,4 kJ/mol. This allows to determine its concentration in the gas mixture by measuring the temperature. The analysis showed that the single-channel flow measurement scheme is the simplest and the most efficient. In order to reduce the measurement time and to take into account the actual temperature of the receiving ozone-containing gas mixture, at the same time it is expedient to determine the temperature of this mixture before and directly in the zone of ozone decomposition using two separate temperature converters.The temperature difference measured by the transducers is proportional to the amount of decomposed ozone, i.e, its concentration in the gas mixture. The construction of the ozone concentration sensor is proposed.The initial temperature of the gas mixture and the temperature in the sensor chamber are measured using two temperature converters, in which diffusion silicon diodes of low power 2D104A are used. The industrial destroyer of ozone "Crete-6" is used for ozone decomposition. It is located in the copper radiator cavity of the sensor in the form of densely packed granules. This ensures a uniform heat recovery from the sites of ozone chemical decomposition. The sensor housing is isolated inside by fluoroplastic gasket and thermostatically is protected by Styrofoam. The performed calculations and studies have shown that the sensor resolution at a concentration is 55,5 mg/m3. The study of the sensor dynamic properties indicated that the most intense rise in temperature is observed during the first 30 minutes of the sensor, and after 1 hour its subsequent change is not significant. Moreover, for the first 15 minutes the signal level of the sensor reaches 70%. Its change for this period of time is the closest to linear dependence. Therefore, it is expedient to use sensor readings 15 minutes after the start of measurements.uk
