ABB AO2000 LS25C EX Product Description
ABB AO2000 LS25C EX is an explosion-proof in-situ laser gas analyzer module of the Advance Optima AO2000 system, adopting TDLAS tunable diode laser absorption spectroscopy. It performs non-contact cross-stack gas concentration measurement directly on process pipes without gas sampling extraction. The EX variant carries ATEX, IECEx and CSA hazardous area certifications for combustible gas environments, delivering continuous, high-selectivity gas monitoring for industrial emission and process control.

Product Features
- TDLAS laser technology with minimal cross-interference between different gas components
- Explosion-proof EX design certified for use in potentially explosive atmospheres
- In-situ cross-stack measurement, no sample conditioning system required
- IP66 protected transmitter and receiver housing with optical purge function
- Automatic pressure and temperature compensation for accurate readings
- Modular integration with AO2000 central controller via Ethernet
- Supports measurement of O2, NH3, HCl, HF, H2S and water vapor
- Built-in self-diagnosis, transmission monitoring and preventive maintenance alerts
- 4-20mA analog output and digital communication for SCADA integration
Application Scenarios
- Power plant flue gas continuous emission monitoring (CEMS)
- Cement, steel and waste incineration furnace gas measurement
- Oil & gas refinery and petrochemical process gas analysis
- Chemical reactor, boiler and kiln in-situ gas monitoring
- Hazardous zone gas detection for combustible and corrosive gas
- Industrial emission compliance monitoring and process optimization
- Retrofit replacement for existing AO2000 LS25 analyzer modules
FAQ
Q1: What is ABB AO2000 LS25C EX?
A: It is an explosion-proof TDLAS in-situ laser gas analyzer module for AO2000 system, used to directly measure gas concentration across stacks and pipelines in hazardous areas.
Q2: Does LS25C EX need sample gas extraction?
A: No, it uses cross-stack in-situ laser measurement. No sampling lines or complex sample conditioning are required.
Q3: What certifications does the EX version have?
A: It has ATEX, IECEx and CSA approvals for explosive atmosphere applications.
Q4: Which gases can LS25C EX detect?
A: Typical measured gases include O2, NH3, HCl, HF, H2S and H2O vapor. Measurement range depends on the specific laser configuration.
Q5: Why does signal transmission drop during operation?
A: Common causes include contaminated optical windows, insufficient purge gas, pipe vibration or misalignment between transmitter and receiver. Clean optics and check purge supply first.
