The pressure monitor makes sure that the lower distribution pressure for nitrous oxide compared to oxygen is kept.
The lower nitrous oxide pressure will be maintained according to standards even when the emergency supply is used through quick connectors or central emergency supply. The pressure monitor is equipped with a digital pressure monitor unit (MC7701) monitoring the current gas pressures, and giving all the visual and acoustic alarms required by standards. The signal to the gas alarm comes from pressure transmitters. The visual and audible signals can be sent to a manned area, if it is required.
The following gases are under surveillance: breathing Oxygen, Nitrous Oxide, Air and instrument Air. The 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.
