TDLS8000 tunable diode laser spectrometer

The Yokogawa TDLS8000 tunable diode laser spectrometer can quickly make in-situ measurements of gas concentrations in combustion and heating processes that are employed in the oil, petrochemical, electric power, iron and steel, and other industries.

The product is used for measuring O₂ concentrations in fired heaters for improved safety and lifecycle management; measuring CO concentration during combustion processes and the amount of moisture in hydrocarbons and corrosive gases; and measuring ammonia concentration for leak detection during DeNox processes.

The device features a cell board that improves absorption peak detection, an important step in the spectral area method. The receiving unit has an auto gain function that can automatically optimise detection sensitivity depending on the measurement object. By increasing the signal-to-noise ratio (S/N ratio), this improves the reliability of measurements taken in coal combustion and other processes where there is high particulate loading.

The product comes with a 7.5″ LCD touch screen, replacing the push-button interface used with preceding models. The light source module containing the laser diode is fully sealed and damage resistant. It can also store up to 50 days’ worth of raw data, accessed remotely.

Designed to meet the requirements for SIL2 certification, the product will help ensure the safe operation of plants. It is also expected to be certified to IECEx, ATEX, FM, cFM and TIIS explosion-proof standards. It will be suitable for installation in hazardous areas with explosion-proof enclosures.
