Calibration of Pressure Gauge Apparatus

The Calibration of Pressure Gauge Apparatus is a compact educational laboratory system designed for practical study of pressure measurement and calibration techniques. Manufactured by Micro Technologies, the apparatus enables students to understand the operation of a Bourdon tube pressure gauge and experimentally calibrate it against known pressures generated using a piston manometer arrangement.

The setup uses a Bourdon tube pressure gauge as the instrument under test. Known pressure is generated through a piston-and-weight arrangement, allowing the applied pressure to be calculated from the known load and effective piston area. The corresponding reading displayed by the pressure gauge can then be recorded and compared with the applied reference pressure.

By gradually increasing and decreasing the applied load, students can obtain a series of pressure readings and develop a calibration curve for the pressure gauge. This procedure helps identify measurement errors and demonstrates important concepts such as accuracy, calibration, repeatability, and instrument response.

The apparatus provides an effective practical demonstration of the relationship between force, piston area, and pressure. Students can compare theoretical pressure values with actual gauge indications and calculate deviations between the reference and measured values.

Its compact bench-top construction makes the apparatus convenient for routine laboratory experiments. The clearly visible pressure gauge, piston assembly, loading platform, and fluid connections simplify operation and allow students to understand each stage of the calibration procedure.

The Calibration of Pressure Gauge Apparatus is suitable for fluid mechanics, hydraulic engineering, mechanical engineering, instrumentation, process engineering, and technical training laboratories where students require hands-on experience with pressure measurement and instrument calibration.

FAQs

What is a Calibration of Pressure Gauge Apparatus?

It is a laboratory apparatus used to study the operation of a Bourdon tube pressure gauge and calibrate its readings against known pressure generated using a piston manometer.

What type of pressure gauge is used in this apparatus?

The experimental setup uses a Bourdon tube pressure gauge, a commonly used mechanical instrument for pressure measurement.

What is the purpose of the piston manometer?

The piston manometer provides a known reference pressure against which the reading of the Bourdon tube pressure gauge can be compared.

How is pressure generated during the experiment?

Known weights are applied to the piston arrangement. The resulting force acting over the effective piston area produces a calculable reference pressure.

Can a calibration curve be prepared?

Yes. Applied reference pressures and corresponding pressure gauge readings can be recorded and plotted to prepare a calibration curve.

Can pressure gauge error be determined?

Yes. The difference between the reference pressure and the pressure indicated by the gauge can be used to determine measurement or calibration error.

Why is a pressure gauge calibrated?

Calibration verifies the relationship between the indicated pressure and a known reference pressure, helping evaluate the accuracy and reliability of the instrument.

What can students learn from this experiment?

Students can learn pressure measurement, Bourdon gauge operation, piston manometer principles, calibration procedures, measurement error analysis, and calibration curve preparation.
