The Pressure Gauge Calibration Apparatus is part of the pressure measurement training system. It is a simple bench-top setup, known as a dead weight gauge tester. The apparatus consists of a horizontal base with an oil pipeline, oil tank, weights holder, and a pressure gauge installed. The system is equipped with a set of weights necessary for conducting the experiment.

  • The system is designed to introduce students to the concept of pressure calibration and the methods used to calibrate pressure gauges.
  • It is a simple benchtop setup, known as the dead weight gauge tester, used for educational purposes in pressure measurement systems.
  • It teaches fluid flow principles and the impact of external forces like gravity and pressure.
  • The system consists of a horizontal base in which the following components are installed:
    • Oil pipeline for fluid flow control.
    • Oil tank for fluid storage.
    • Weights holder to support the set of weights used for calibration.
  • Pressure gauge to measure the fluid pressure generated by the applied weights.
  • The system includes a specific set of weights necessary to generate measurable pressure for calibration.
  • The hydraulic pump powers the system and is responsible for generating pressure in the oil tank, ensuring fluid pressure is applied during experiments.
  • The oil reservoir supplies the fluid necessary for the pressure measurement process and ensures consistent fluid flow during testing.
  • The piston applies pressure based on the weight placed on it, transmitting this pressure to the pressure gauge.
  • The calibrated pressure gauge measures the pressure created by the applied weight.
  • The readings from the pressure gauge are compared to expected values to verify calibration accuracy.
  • A pressure regulator controls the fluid pressure, allowing precise calibration levels.
  • The system follows the dead weight tester principle, where weights create pressure measured by the gauge.
  • It ensures accurate calibration by providing a stable pressure reference for verifying instruments.
  • Users can adjust the weight on the piston to test calibration at different pressure levels.
  • This trainer helps students understand pressure measurement principles, force, and pressure relationships.
  • It provides practical training in using and calibrating pressure gauges for industrial applications.
  • The oil cycle is designed to be free of air bubbles, ensuring smooth operation without interference.
  • The setup includes instructions to ensure the oil tank is filled and the pump is correctly oriented.
  • Step-by-step guidance is provided for safe and effective operation during the setup and calibration process.
  • Students gain hands-on experience with a known calibration standard for precise industrial measurements.
