Boyle’s Law Apparatus TH-3103A
Product Overview
The Boyle’s Law Apparatus TH-3103A is a comprehensive thermodynamics training system designed to demonstrate and verify Boyle-Mariotte’s Law through practical experimentation. The apparatus enables students, researchers, and engineering trainees to investigate the relationship between pressure and volume of a gas at constant temperature, providing a clear understanding of fundamental gas laws and thermodynamic principles.
Knowledge of gas laws is an essential requirement for studies in thermodynamics, mechanical engineering, mechatronics, process engineering, and applied sciences. This apparatus allows learners to observe and analyze the behavior of air as a test gas under controlled compression and expansion conditions. Through its transparent measuring vessel and integrated measurement systems, users can directly visualize the thermodynamic processes occurring inside the system.
The TH-3103A provides an ideal platform for studying isothermal state changes, where temperature remains nearly constant while pressure and volume vary. By changing the volume of enclosed air using a hydraulic oil system and pump arrangement, students can accurately verify the inverse relationship between pressure and volume described by Boyle’s Law.
Key Features
✔ Experimental Verification of Boyle’s Law
The apparatus allows users to experimentally verify the fundamental gas law:
Pressure × Volume = Constant (at constant temperature)
Students can perform controlled experiments and compare measured values with theoretical calculations.
✔ Transparent Measuring Vessel
A large transparent vessel enables direct observation of volume changes in the enclosed air. This visual learning approach enhances understanding of thermodynamic processes.
✔ Isothermal Compression and Expansion
The system is specifically designed for investigating isothermal processes. Slow compression and expansion ensure that temperature remains approximately constant during experimentation.
✔ Integrated Hydraulic Volume Control
Hydraulic oil filling is used to vary the volume of the test gas smoothly and precisely, enabling accurate experimental results.
✔ Built-in Pump System
The apparatus includes an integrated pump capable of generating the required pressure differences for volume adjustment.
✔ Vacuum Pump Functionality
The compressor can also operate as a vacuum pump, allowing experiments involving pressure reduction and gas expansion.
✔ Electronic Temperature Measurement
Temperature is continuously monitored using electronic sensors to ensure reliable thermodynamic analysis.
✔ Pressure Measurement System
A pressure gauge and sensor arrangement provide accurate pressure readings throughout the experiment.
✔ Compression and Expansion Control
A 3/2-way valve enables convenient switching between compression and expansion modes.
✔ Optional Computer-Based Data Acquisition
The optional TH-3103ASW software provides automated data acquisition, calculation, monitoring, and reporting capabilities using National Instruments™ LabVIEW™ technology.
