Pressure measurement is important in any branch of Science and Engineering. Bourdon tube pressure gauges are extensively used in industry. Proper calibration of these gauges is essential to make accurate pressure measurements. Calibration using dead weights is a direct method commonly used for industrial Bourdon tube pressure gauges. Sci-tech Dead Weight Pressure Gauge Calibrator Model FM 10 is important equipment necessary for any Fluid Mechanics and Hydraulics Laboratory of an educational institution.     

Sci-tech Dead Weight Pressure Gauge Calibrator Model FM 10 is a bench top dead weight pressure gauge calibrator consists of a precision machined piston and cylinder assembly mounted on levelling screws. A Bourdon gauge is supplied for calibration. The weights supplied are added to the upper end of the piston rod which is rotated to minimize friction effects. The gauge is thus subject to known pressures which may be compared with the gauge readings and an error curve drawn. Detailed Operation & Maintenance Manual is provided along with the trainer.

Sci-tech Pressure Gauge Calibrator FM 10 has been designed to demonstrate the principle of calibration using dead weights and enable students calibrate a Bourdon tube pressure gauge of interest to the education and industry. It consists of a vertically mounted precision machined leak proof piston and cylinder assembly mounted on a base with leveling screws. The piston rod has an extension and a platform to place weights during calibration. A set of weights and a Bourdon tube pressure gauge are supplied with the apparatus.

The cylinder is connected to the gauge through a system of leak proof valves and flexible tubing. A non-return valve is fitted at the water supply side of the cylinder. Blanking pug is provided to drain water from the apparatus. The gauge can be subjected to known pressures by placing different weights on the piston. Applied pressures can be calculated and the values compared with the readings obtained indicated on the pressure gauge scale. The Pressure Gauge Calibrator can also be used to calibrate other Bourdon type pressure gauges with proper tubing connections.

Water can be supplied from the FM100 Hydraulic Bench or any other source.

Optionally, unit allows pressure gauges to be accurately calibrated up to 300 bar, with an accuracy of ±0.015%.
