A-2C Micro TELEDYNE Fuel Cell Sensor For Oxygen Analyzers

A-2C Teledyne Micro-Fuel Cell Sensor For Oxygen Analyzers

SPECIFICATIONS
 
 

Manufacturer :Teledyne Analytical Instruments

Product No. : A-2C, Used for trace O2 measurements in CO2 containing backgrounds (0.1-100% CO2). CO2 must be present. Use where acid gases are present (CO2, HCl, HCN, etc). CO2 must be present.

Introduction:
Teledyne’s patented Micro-fuel Cell (MFC) is a unique,electrochemical transducer that provides versatile oxygen sensing capability by combining the following features.
 
Specificity to Oxygen
Completely maintenance free
Absolute zero - requires no “zero” gases
Long life
Long term stability, two to four weeks (and longer) calibration interval
Unaffected by variations in sample flow rate
Unaffected by shock, vibration or position
 
Theory of Operation
Oxygen in the gas space surrounding the cell diffuses through a Teflon membrane and is reduced on the surface of the cathode. A corresponding oxidation occurs at the anode internally and an electrical current is produced that is proportional to the concentration of oxygen.
 
Cathodic reaction: 4e- + 2 H2O + O2 arrow 4 OH
Anodic reaction: 2 OH- = Pb arrow PbO + H2O + 2e
Overall reaction: 2 Pb + O2 arrow 2 PbO
The transducer operates thusly as a fuel cell, and its output is limited only by the rate at which oxygen enters the cell and the amount of anode material stored within. This output is insufficient for the cell to be utilized as a power source, which is the purpose of most fuel cells. However, the cell does provide sufficient output to drive meters directly or, after amplification, will provide outputs capable of performing more complicated functions
 
 
Physical Characteristics
The MFC is a sealed, disposable oxygen transducer that measures 1.25 inches in diameter and is .75 inches thick. It has a relatively large sensing area (0.7 inches diameter) that produces a high level output signal that does not require amplification to drive analog display devices.
 
The large sensing area also reduces the reading errors associated with vapor condensation from sample streams that normally cause small sensing area transducers to read low or even zero.
 
The rear of the MFC is covered by a contact plate that consists of two concentric foils. These foils mate to spring loaded contacts in the various probe assemblies and sample manifolds in which the cells are housed.
