Air specific heat capacity ratio measurement (i.e. air adiabatic exponent measurement) is one of the
important teaching experiments of common physics and has been included into the syllabus of physics experimental teaching of universities. In order to cooperate with universities and colleges to realize modernization of teaching appliances, improve the experimental quality, University and our company have jointly developed this new generation of air specific heat capacity ratio measuring apparatus. Air specific heat capacity ratio measurement is introduced in most common physics experimental teaching books.Commonly they use U-shaped mercury gauge or water pressure gauge to measure the pressure of air, and use mercury thermometer to measure temperature. Because the pressure measurement has low accuracy if it is done with mercury thermometer, measuring result is rough and experiment error is high. Air specific heat capacity ratio measuring apparatus is a new generation of experimental instrument based on the original experimental apparatus. It uses silicon pressure sensor to measure pressure of air, and uses integrated temperature sensor to measure temperature, so measurement of air pressure and temperature is accurate and sensitive. Error of measured air specific heat capacity ratio is within 3% comparing with standard value. Meanwhile, students can learn the principle and operating method of advanced silicon pressure sensor and semiconductor integrated temperature sensor, which greatly enriched the teaching contents. Air specific heat capacity ratio measuring apparatus is equipped with an additional stabilized voltage power supply and sampling resistance, so it is not necessary to connect A battery and resistance box outside.
