|Yokogawa Tunable Laser Diode|
Companies are always looking for ways to optimize processes by saving energy, reducing CO2 emissions, and improving safety and one way to do this is by optimizing the air-fuel ratio in the combustion process. To accomplish this, sensors are needed that can continuously monitor the concentration of O2 and CO+CH4 in the radiant section of fired heaters.
- Highly reliable measurement - The TDLS8000's laser module includes a newly developed reference cell board that improves the reliability of absorption peak detection, which is an important step in the spectral area method. In addition, the receiving unit employs a new auto gain function that can automatically optimize 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. Designed to meet the requirements for SIL2 certification (certification pending) defined by the International Electrotechnical Commission (IEC), the TDLS8000 will play a key support role in ensuring the safe operation of plants.
- Improved operability and maintenance efficiency - The TDLS8000 comes with a large 7.5-inch LCD touch screen that can display a greater variety of data. The touch screen replaces the push button interface used with preceding models, making the setting of parameters easier and more intuitive. The light source module containing the laser diode is fully sealed and damage resistant. To facilitate troubleshooting and reduce downtime, this module is able to store up to 50 days' worth of raw data that can be accessed anywhere in the world by, for example, a Yokogawa response center.
- Compact size - The redesigned TDLS8000 is just three-quarters the size and weight of the preceding model, allowing it to be installed in a greater variety of locations.
