The Department of National Defence has a requirement to replace
the outdated Oxygen Monitoring systems for the Main
Recompression Chambers and SubSAR Recompression Chambers located
at the Fleet Diving Unit (Atlantic) in Shearwater, Nova Scotia
and Fleet Diving Unit (Pacific) in Victoria, British Columbia. 

The Oxygen Monitor is for ambient monitoring or for measuring
gas samples from a recompression chamber. When used in
conjuction with a gas sample line from the living chamber it can
be configured to provide oxygen readings (% O2).

Characteristics. The basic Oxygen Monitor unit should have the
following characteristics:

High and Low audible and visual alarms with false alarm
suppression;

Dual resolution - increases the resolution on the lower end of
the scale or low levels
(deep depths) when accuracy is critical;

Between four (4) and five (5) inch digital LED (Light Emitting
Diode) display for
easy reading;

Universality of power voltage: 97-260 Volts AC / 9-33 Volts DC
/12-24 Volts AC;

Output = 0 - 1 Volt (Standard: For local recording devices,
local repeater);

Panel Mount with Hyperbaric readings in millibar PP02 (partial
pressure Oxygen)
where the sensor is located inside the recompression chamber and
provides a direct
reading of chamber partial pressure oxygen levels;

Height = Approx. 5 inches, Width = Approx. 4 inches, Depth =
Approx. 10 inches,
Weight = Approximately 4 pounds; and

Variety of sensor options (i.e. Analox 9212 three year
disposable series with builtin
temperature compensation; Teledyne B1 or C3 disposable type
which requires a
separate temperature compensating module; the 100HYP MKIII
Internal Chamber


Analyzer or the Infinite Life Paramagnetic Sensor) with disposal
due-date between one
and three year that can be used inside and outside the
recompression chamber.

Performance Requirements:

Capabilities. The Oxygen Monitor is to be mounted directly on
the control panel
and be readable standing up, to the majority of operators. It is
preferable that the monitor
provides continuous on-line analysis of recompression chamber
air. It should include a
battery back -up in case of main power failure. It should also
have power ON/OFF switch,
battery check controls and an alarm suppression capability, for
the visual and audible
alarms. The monitor shall be capable of being calibrated
manually or the factory
calibration settings being restored.

Operational Availability & Flexibility. We are dealing with two
Recompression
Chamber systems that are fixed and inside a building and two
other systems that are
mobile and may be exposed to higher air salinity levels when
deployed in a sea-going
environment.


Physical Requirements:

Interchangeability. The level of assembly of the Oxygen Monitors
at which
compon
