hOSPiTal cenTRal GaS SYSTeM PRESSURE MONITOR DN15 ediTiOn 1/2012 The pressure monitor makes sure that the lower operating pressure for nitrous oxide compared to oxygen is kept. When the spare supply is used to keep the gas division going, the pressure monitor will supervise the operating pressures to make sure that these are within the established standards. Furthermore, an optic and acoustic signal to a manned area will be obtained. The pressure monitor is equipped with a digital pressure reading unit (MC 7701). The surveillance is done by pressure transmitters. The FOllOWinG GaSeS aRe UndeR SURVeillance: breathing oxygen, nitrous oxide, and instrument air. Alarm is indicated by an acoustic and and visual signal at the same time as the exact cause of the alarm is written on the display. This happens if the gas pressure rises above or sinks below the set maximum or minimum limits respectively. The pressure monitor is also equipped with bayonet coupling for breathing oxygen, nitrous oxide, breathing air, and instrument air. When necessary, it is possible to connect spare gas to these.
