Product description
Overview
Yokogawa’s TDLSTM8200 is a dual laser gas analyzer that measures the concentration of O2, CO, CH4, NH3, HCl ,which are important for combustion control and safety related measurements with the ability to measure various other NIR absorbing gases.
The TDLS8200 is installed in-situ, directly into the process eliminating the need for sample extraction and conditioning providing a near real time measurement. The single flange design reduces installation costs and expands installation flexibility where traditional cross-duct analyzers were not feasible due to obstructions or accessibility. Based on solid-state technology means virtually no measurement drift and reduced calibration frequency. The analyzer auto-gain feature and reference cell ensures measurements are unaffected by dynamic process conditions, upsets, or varying background composition to maintain real time measurements.
The modular design of the TDLS8200 allows for full field serviceability with the ability to replace components without having to return the analyzer to the manufacturer. A storage period of up to 50 days of data, spectra, and history files (validation and configuration changes) allow for advanced diagnostics and provides invaluable information into analyzer performance and process details.
Features
• Dual laser measurement technology allows for O2, CO, and CH4 to be measured in-situ with a single analyzer
• TruePeakTM combined with smart laser technology
- Measurement integrates the area of the absorbance and gets a true, interference-free analysis under changing pressure, temperature, and background.
- Laser Detector Module is replaceable on site without any calibration or adjustment.
- Internal reference cell in the Laser Detector Module ensures peak locking during trace measurements.
- Laser Detector Modules are isolated from aggressive and corrosive processes.
- On board diagnostics and low TCO(*1) (no moving parts, high MTTF(*2) for components)
*1: Total Cost of Ownership
*2: Mean Time To Failure
