FLUID MECHANICS F1-10 Accessory
F1-11 Dead Weight Pressure Gauge Calibrator - Issue 19
This calibrator functions on the same principle adopted in calibrating industrial pressure gauges.
- Precision machined piston and cylinder with levelling screws
- Bourdon gauge with inlet and outlet valves
- Set of weights
- Educational software available as an option
The 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 minimise friction effects.
The gauge is thus subject to known pressures, which may be compared with the gauge readings and an error curve drawn.
|Pressure gauge:||Bourdon tube range 0 to 200 KN/m2 (KPa)|
|Area of piston:||244.8 x 10-6 m2|
|Mass of piston:||0.5kg|
|Ancillary masses:||2x 0.5kg, 1.0kg and 2.5kg|
