The GalvanicOxygen Cell DN type is a diffusion limited metal/air battery. The oxygen inthe sample diffuses through the barrier and reaches the cathode. Here it isreduced to hydroxyl ions which, in turn, pass through the electrolyte tooxidize the metal anode.

A Current, proportional tothe rate of consumption of oxygen, is generated when the cathode/anode circuitis completed, the Galvanic Oxygen Cell operating in what is virtually ashort-circuit condition.

The cell current of is adirect function of the rate at which oxygen reaches the cathode.

Technical Specifications of Galvanic Oxygen Cell DN Type

Range：

1ppm to 50% or 100ppm to 50%O₂ (in inert gases)

Typical Cell Life：

100,000 oxygen % hours or 2 years, whichever is thesooner.

Stability

Better than 2% of reading per month, or 1ppm whichever isgreater.

Sample Flow

Between 100 and 300 ml/min for optimumoperation.

Sample Pressure

The pressure applied to the cell isdetermined by the vent pressure which should be atmospheric for quoted accuracy.Note: The sensor must not be subjected to rapid pressure changes.

Sample Temperature

-5 to +40°C (non-condensing)

Speed of Response

T90 is variable depending on sensor andconcentration and is approximately 3s at % levels and 20s at ppm levels. Theppm figure assumes that the sensor is purged down.

Environmental Conditions

Temperature

0 to 40 °C - continuous

-5 to + 50 °C – intermittent

Altitude

up to 2000m

Humidity

Max relative humidity 80% non-condensing

Pollution degree

Pollution degree 2
