Air Quality Monitor for NO2

NO2 is produced naturally by the combustion processes within the internal combustion engine and is emitted from

the tail pipes of all types of vehicles. NO2 is also particularly toxic and prolonged exposure to levels as low as a

few hundred parts per billion will have a detrimental effect on human health. There is a growing international

requirement to measure and limit the levels of NO2 within road tunnels to reduce the exposure of tunnel users to

this toxic gas.

Previous attempts to continuously measure NO2 levels in tunnels have failed due to either insufficient accuracy

of measurement or too great a complexity and cost of the measuring instrument, resulting in unacceptable levels

of maintenance and measurement availability.

The CODEL NO2 Air Quality Monitor resolves these issues by means of a very simple but accurate measurement.

The CODEL sensor is a precision transmissometer which measures the attenuation of blue light by NO2 in the

tunnel atmosphere. The light source is a simple LED and the interfering effects of particulates in the atmosphere

are eliminated by making the measurement within a 1m diffusion cell into which the atmospheric gases, but not

the particulates, can freely diffuse.

The result is a very accurate and stable sensor having no moving components and requiring no maintenance

throughout its lifetime. Even the optics remain clean because they are contained within the diffusion cell which

prevents the deposition of dirt on the optical surfaces. The filters through which the gas diffuses do not become

blocked because the diffusion process exerts no pressure on particulates to force them into the filter pores.

Fully configurable analogue and alarm outputs are generated inside the Tunnel Display Unit (TDU). In addition

there is an RS485 output that can be utilised to deliver MODBUS protocol to a SCADA system located in the

tunnel control centre.

The NO2 Air Quality Monitor system arrangement is illustrated in Figure 1.
