TDLS8000

TDLS8000

The TDLS8000 is a robust and advanced in-situ gas analyser from Yokogawa, designed for continuous and accurate measurement of gases such as O₂, CO, CO₂, H₂O, NH₃ and HCl in demanding process environments. It utilises tunable diode laser spectroscopy, reducing the need for sampling and ensuring fast real-time monitoring.

The TDLS8000 is specially designed to handle harsh process conditions, including high temperatures and corrosive environments. With its compact design and explosion-proof capability, it enables reliable measurements in hazardous areas without the need for maintenance-intensive sampling equipment. It features an intuitive 7.5-inch colour display for local or remote monitoring and can be connected via HART or Modbus TCP for remote diagnostics and configuration.

Features and benefits:

  • Real-time feedback: Enables fast feedback to process control for optimised operation and safety.
  • Compact and robust design: Easy to install and requires minimal maintenance.
  • Direct measurement: Eliminates the need for sampling systems and reduces operating costs.
  • High accuracy: Also measures low gas levels using the reference cell.
  • SIL2 certified: Safe for use in hazardous environments and can be configured to SIL3 with dual analysers.
