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. The tester and gauge assembly are manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and can be ordered from the factory by colleges, ITIs, tender contractors and distributors.
Specifications
The gauge calibration apparatus is described row by row in the table. In essence, weights on a platform put a known force on a piston of known area, and a flexible water-filled tube carries that pressure to a thin-walled, oval-section Bourdon tube bent into an arc, fixed at the pressure end and free at the pointer end.

Applications and Experiments for the Bourdon Gauge Calibration Apparatus
Weights are added in increments with the gauge reading recorded at each step, then removed with readings taken again. Comparing these readings with the pressure calculated from weight and piston area gives the gauge error, and its likely causes can then be discussed, a calibration exercise that suits 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?
Both the dead weight tester and its transparent-dial gauge are made at Science Lab Supplies' Saha, Ambala workshop in India, and prices for the unit are set by the company itself, not by 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.
