PRACTICAL POSSIBILITIES

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 deadweight 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.

SPECIFICATIONS SUMMARY

TMCP. Pressure Measurement and Calibration Unit is designed to study pressure and how different methods and techniques can be used to measure this variable.
This unit introduces students to pressure, pressure scales and common devices available to measure pressure.
Bench-top unit mounted on an anodized aluminum structure and panel in painted steel.
Dead-weight pressure calibrator, using water, consists of a precision piston and a cylinder, with a set of weights to generate different pressures.
Bourdon type manometer, connected to the dead-weight calibrator.
Electronic pressure sensor, connected to the dead-weight calibrator.
Both Bourdon manometer and pressure sensor are mounted on a manifold block with a separate reservoir (to contain water) .
Valves for allowing the priming, restricted flow of water to demonstrate the application of damping and the connection of other alternative devices for calibration.
Electronic console: Protection devices. Sensor connectors.
Digital meter with selector switch to display the output from the pressure sensor and the conditioned reading in engineering units. Conditioning circuit with span and zero controls to allow the output to be displayed as a direct
reading pressure meter calibrated in units of pressure.
Cables and Accessories, for normal operation.
Manuals: This unit is supplied with 8 manuals.

Dimensions (approx.):  Unit: 500 x 350 x 350 mm. Weight: 15 Kg.  Electrical console: 310 x 220 x 145 mm. Weight: 3 Kg.
