Abstract
A special sensitive element based on the novel composite material was created. The sensor has a linear calibration and is resistant to aliphatic hydrocarbons, in particular aviation fuel. A low cost and easyto-implement method for calibrating the sensor was proposed. Temperature dependence of the oxygen mass transfer coefficient kl was measured for aviation fuel TS-1 (Russian equivalent of Jet A-1) in the temperature range of 10 to 40 °C as a demonstration of the sensor capabilities. The dependence found obeys the Arthenius equation with the parameters EA= 21.7 + 1.5 kJ/mol, klo = 1080 + 90 m.h? The resistance to mechanical action is one of the important advantages over the sensor made of a sol-gel matrix with a protective coating, Damage to some part of the surface does not change the properties of the entire sensor, since the composite material contains a large number of isolated particles with a dye.
Farsi abstract
يك عنصر حساس ويژه بر اساس مواد كامپوزيتي جديد ابداع گرديد. سنسور مورد نظر يك كاليبراسيون خطي دارد و به هيدروكربن هاي آليفاتيك، مخصوصا سوخت هواپيما، مقاوم است. يك روش كم هزينه و آسان براي پياده سازي كاليبراسيون سنسور پيشنهاد شده است. وابستگي دما به ضريب انتقال جرم اكسيژن KL براي سوخت هواپيما 1-TSمعادل روسي (1-Jet A)
در محدوده دما 10 تا 40 درجه سانتيگراد ظاهرا قابليت هاي اندازه گيري سنسور را دارد. وابستگي مشخص شده مطابق معادله آرنينوس با پارامترهاي klo = 1080 – 90 m-h-1 EA = 21.7+ 1.5 kJ/mol است.
مقاومت در برابر فعاليت مكانيكي يكي از مزاياي مهم در برابر حسگر ساخته شده از ماتريس sol - gel با پوشش محافظتي است. آسيب به برخي از قسمت هاي سطح خواص كل سنسور را تغيير نمي دهد، زيرا مواد كامپوزيت شامل تعداد زيادي ذرات جدا شده با رنگ را دارند.
