A complete system therefore consists of:
An Operator Console intended for installation in control rooms. (It is assumed the control room is
at normal atmospheric pressure. Special versions are available if it is required to mount in the
hyperbaric environment).
One or more sensor units of types REM1, REM2 and/or REM3 intended for installation in hyperbaric
(or hypobaric) environments. Note special versions of REM1 and REM3 may be configured to be
mounted externally, and take sample flow from a hyperbaric chamber.
Systems will normally be purchased to operate over a defined range of pressures. For instance a
hyperbaric saturation diving system may be rated between 0.8 and 35 bar absolute (other variants
also available); a hyperbaric air diving system may be rated between 0.8 and 10 bar absolute;
whilst a hypobaric flight simulator chamber may use a system rated between 0.1 and 2 bar
absolute.

Brief Overview
A large graphic display on the Operator Console shows the value of each measured parameter.
The remote units provide local displays of the monitored parameters (although note that some
special versions of remote sensor are not fitted with displays).
The Operator Console provides audio and visual alarms for the measured gas parameters. The
alarm set-points may be easily adjusted using the pushbuttons on the Operator Console. The
Remote sensor can also provide audio and visual alarm indication.
The overall system can be powered by a single supply connected to the rear of the Operator
Console. The remote unit may be connected to the Operator Console, from which it can obtain its
power, or it can be separately powered.
The sensors are housed in splash proof enclosures that are vented to prevent implosion/explosion
in hyperbaric/hypobaric environments. Gas levels are monitored by sensors built into the REM1
(and REM3 when fitted) unit. Gas enters the sensors through waterproof membranes.
The user should ensure that the gas inlet ports remain as clean as possible to prevent the
waterproof membranes becoming blocked. The sensor enclosure vent must also be kept clean.
