SITRANS TDL is an in-situ tunable diode laser analyzer, designed for fast, selective and sensitive measurement of numerous different gases, including O2, NH3, H2O, CO, CO2, CH4, HCl, HF, H2, H2S, CH2O and many more.
It consists of a pair of cross-duct sensor units which are directly installed at the measuring point in the plant, making it the ideal solution for non-contact measurement of gas concentrations.
In-situ tunable diode laser (TDL) measurement with no sample conditioning — reducing maintenance, eliminating consumables and improving uptime in harsh process conditions.
Rapid, continuous measurements support tighter control loops, quicker detection of process deviations and improved product quality and safety.
High selectivity and stable performance across challenging temperatures, dust and moisture — delivering reliable results for emissions monitoring and critical process applications.
In situ cross‑duct design puts the laser across the gas stream so you read true concentrations without sample conditioning or lag.
IP66 enclosures and high‑temperature operation (O₂ up to ~1100 °C) support reliable performance in furnaces, kilns and incinerators.
Use integrated Ethernet and common industrial interfaces with a browser‑based UI for configuration, monitoring and diagnostics.
