Pressure Measuring Apparatus

Pressure Measuring Apparatus .
Description of Pressure Measuring Apparatus for Science Lab Equipment Laboratory Instruments Manufacturers, Engineering Lab Equipments Manufacturers
The apparatus consists of a series of pressure/vacuum measuring instruments mounted on a wheeled bench with an electrically driven rotary vane pump to provide the necessary pressure and vacuum. The measuring instruments include a sloping, liquid filled manometer reading pressure from 0 to 75mm of water, a vertical manometer reading from 0 to 200 mm of water, a manometer reading from 0 to 760 mm, a pressure transducer with analogue readout and a Bourdon tube gauge scaled - 1 to 2.5 bar for reading both pressure and vacuum. Pressure variations are made by the rotary vane pump which is provided with needle valves at entry and discharge. A further valve is incorporated at the pump outlet with pressure tappings either side of it to enable differential pressure measurements to be made and plugs are supplied to blank off any connections not in use.The bench also includes a microprocessor based portable digital pressure calibrator for pressures between -1 and 10 bar.
