Pressure Measurement and Calibration Unit- Engineering Lab Training Systems Description and Specifications for Lab Tenders
EXERCISES AND PRACTICAL POSSIBILITIES
Some Practical Possibilities of the Unit:
1.- Study the concept of pressure.
2.- Study
of the concepts of measurement and calibration (gauge and absolute
pressures, zero error, non-linearity, scale error, conversion of
arbitrary scale into energy units).
3.- Study of pressure scales.
4.- Study of the function of a dead-weight pressure calibrator.
5.- Study of the operation of a Bourdon type manometer.
6.- Study of the characteristic behaviour of a Bourdon type manometer.
7.- Calibration of a Bourdon type manometer in engineering units.
8.- Calibration of a Bourdon type manometer in arbitrary units (angular displacement of needle).
9.- Study of the characteristic behaviour of a pressure sensor.
10.- Calibration of a pressure sensor and signal conditioning circuit in engineering units.
11.- Calibration of a pressure sensor (voltage output from sensor).
12.-
Study of the sources of error in measurement and calibration (signal
conditioning, display resolution; wear, friction and backlash, etc.).
13.- Study of calibration of conditioning circuits and display using a reference signal. Fluid Mechanics Lab Equipments manufacturers.
