AIR SPECIFIC HEAT CAPACITY RATIO MEASURING APPARATUS Manufacturer,and suppliers in China,
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. Air specific heat capacity ratio measurement is introducedin 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 experimenterror is high. Air specific heat capacity ratio measuring apparatus is a new generationof experimental instrumentbased on the original experimental apparatus.It uses silicon pressure sensor to measure pressure of air, and uses integratedtemperature 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 integratedtemperature sensor, which greatly enriched the teaching contents. Air specific heat capacity ratio measuring apparatus is equipped with an additionalstabilizedvoltage power supply and sampling resistance, so it is not necessary to connect A battery and resistancebox outside.
EXPERIMENTS:
1. Measuring the ratio of air specific heat capacity at constant pressure to specific heat capacity at constant volume.
2. Observing air state changing during thermodynamic process and its basic principle.
3. Learning the principle and method of accuratelymeasuring air pressure and temperature with sensor.
