Calibration of a Bourdon Pressure Gauge
Product Code : LSK-FM-10458
Calibration of a Bourdon Pressure Gauge (SKU LSK-FM-10458) is a Bourdon gauge connected to a dead weight tester, used to teach Bourdon tube theory, calibrate the gauge and compare measured readings with theoretical pressure. The transparent dial shows the working mechanism, which makes it a clear practical for engineering and instrumentation students. Science Lab Supplies, which manufactures its fluid mechanics range at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, supplies the unit directly to colleges, ITIs, tender contractors and distributors.
Specifications
Weights placed on a platform put a known force on a piston of known area, so the applied pressure can be calculated. A flexible water-filled tube carries that pressure to the Bourdon tube: a thin-walled tube of oval section bent into an arc, fixed at the pressure end and free at the pointer end.

Applications and Experiments for the Bourdon Gauge Calibration Apparatus
Students add weights in increments and record the gauge reading at each step, then remove them and record again. Comparing these readings with the pressure calculated from weight and piston area gives the gauge error, and students discuss its likely causes, a core calibration exercise in fluid mechanics lab experiments.

Frequently Asked Questions
How does a Bourdon gauge work?
Pressure enters the fixed end of a curved, oval-section tube. As pressure rises the tube tries to straighten, and its free end moves the pointer by an amount proportional to the pressure increase.
How is the true pressure known during calibration?
The weights apply a known force to a piston of known area, so pressure equals force divided by area. That value is compared with the gauge reading.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is a manufacturer. The tester and gauge assembly are produced in its Saha, Ambala workshop in India, and prices are quoted by the company itself rather than a dealer.
How does it differ from the Pressure Measurement Bench?
This unit is the gauge and dead weight tester alone. The Pressure Measurement Bench adds a separate panel of manometers and vacuum and pressure gauges driven by a syringe.
Related Pressure Measurement Equipment
These four items build on the calibration exercise: a bench that pairs gauge calibration with manometers, a multi-gauge display panel, a hydrostatics bench that includes its own calibrator, and a rig where a Bourdon gauge checks an electronic transducer.
