City Technology’s 5 Series range of premium gas sensors has been designed to ensure optimal performance within the harsh environments of flue gas analysers and combustion efficiency monitors. Sensors are available for oxygen, carbon monoxide, nitric oxide, nitrogen dioxide and sulphur dioxide, along with a hydrogen-compensated carbon monoxide sensor.
CiTiceLs are designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage, fitting into instruments, and operation.
When using sensors with printed circuit boards (PCBs), degreasing agents should be used before the sensor is fitted. Do not glue directly on or near the CiTiceL as the solvent may cause crazing of the plastic.
Cross Sensitivitv Table
Whilst CiTiceLs are designed to be highly spécifie to the gas they are intended to measure, they will still respond to some degree to various other gases. The table below is not exclusive and other gases not included in the table may still cause a sensor to react.
IMPORTANT NOTE : The cross sensitivity data shown below does not form part of the product spécification and is supplied for guidance only. Values quoted are based on tests conducted on a small number of sensors and any batch may show significant variation. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.
Gas Cross Sensitivity (%)
Hydrogen Sulfide (H2S) ~ -25
Sulfur Dioxide (S02) ~ -3
Nitric Oxide (NO) < 1
Hydrogen (H2) < -1
Hydrogen Chloride (HCl) < -1
Ethylene (C2H4) < -1
