Kenotometer
Vacuum Gauge
Manufactured by Brady & Martin Ltd Newcastle on Tyne This instrument is used in steam turbine condensers which are operated at pressures below atmospheric pressure. (In a vacuum condition). It measures pressures approaching a perfect vacuum. (0 pressure absolute). The absolute pressure is indicated by a mercury column, usually expressed in inches of mercury. This Instrument measures the very low Absolute pressure in the condenser. The pressure would be about 1.5 inches of mercury from the 0 at the bottom of the scale Barometric pressure would be 30 inches of mercury |
