Pressure Measurement Bench TH-3102
Product Description
The Pressure Measurement Bench (TH-3102) is a comprehensive thermodynamics laboratory training system designed to demonstrate, compare, and calibrate various pressure measurement techniques used in engineering and industrial applications. This advanced educational bench enables students, technicians, and researchers to gain practical experience in measuring positive pressure, vacuum pressure, and pressure differences using multiple measuring instruments.
The system incorporates a wide range of pressure measuring devices including U-tube manometers, inclined tube manometers, Bourdon tube manometers, a digital pressure transmitter with display, and a dead weight pressure calibrator. Through these instruments, users can study the operating principles, accuracy, sensitivity, and calibration procedures of different pressure measurement methods.
Test pressures in the millibar range can be easily generated using the supplied syringe or hand pump. All manometers can be interconnected using flexible hoses, allowing direct comparison of readings obtained from different measurement techniques. This arrangement provides an excellent understanding of gauge pressure, vacuum pressure, and atmospheric pressure relationships.
A key feature of the TH-3102 is the inclusion of a Dead Weight Pressure Calibrator, which serves as a highly accurate reference standard for pressure calibration. The calibrator consists of a precision-machined piston-cylinder assembly mounted on leveling screws. By applying known loads through calibrated dead weights, a precise pressure is generated according to the force-to-area relationship. Hydraulic oil transfers this pressure to the measuring instruments, enabling accurate calibration and performance verification.
The dead weight tester allows users to evaluate instrument accuracy, identify measurement deviations, create error curves, and perform calibration procedures on mechanical pressure gauges and manometers. The piston assembly is specifically designed to minimize friction effects, ensuring highly repeatable and reliable calibration results.
This laboratory equipment is ideal for thermodynamics, fluid mechanics, instrumentation, process engineering, and mechanical engineering laboratories where practical understanding of pressure measurement and calibration is required.
