Yokogawa Corporation of America releases the TDLS8000 Tunable Diode Laser Spectrometer.

Yokogawa Corporation of America releases the TDLS8000 Tunable Diode Laser Spectrometer. The TDLS8000 makes in-situ measurements of gas concentrations in various process conditions that are employed in the oil, petrochemical, electric power, iron and steel and other industries. As the successor to the TDLS200 laser gas analyzer, the TDLS8000 offers improved reliability and operability. The original platform of the TDLS200 was developed off of a U.S. Department of Energy program, In Situ Sensors for the Chemical Industry.

The TDLS8000’s laser module includes a newly developed reference cell board that improves the reliability of absorption peak detection. The receiving unit employs a new auto gain function that can automatically optimize detection sensitivity depending on the measurement object. Increasing the signal-to-noise ratio (S/N ratio) improves the reliability of measurements taken in applications with varying levels of particulates. The TDLS8000 is designed to meet the requirements for SIL2 certification (certification pending) defined by the International Electrotechnical Commission (IEC).

The TDLS8000 comes with a 7.5-inch LCD touchscreen that can display a greater variety of data. The touchscreen replaces the push button interface used with preceding models. The light source module containing the laser diode is fully sealed and damage resistant. To facilitate troubleshooting and reduce downtime, the module can store up to 50 days’ worth of raw data. The redesigned TDLS8000 is 3/4 the size and weight of the preceding model. The TDLS8000 is certified to the IECEx, ATEX (Europe), FM (U.S.), cFM (Canada), and TIIS (Japan) explosion-proof standards. It is suitable for installation in hazardous areas that required the use of an explosion-proof enclosure.

Applications include:

• Measurement of O2 concentration in fired heaters.

• Measurement of CO concentration during combustion .

• Measurement of trace moisture in hydrocarbons and corrosive gases.

• Measurement of ammonia concentration for over injection during DeNox process.
