Overview
The TDLS Probe brings all the industry-leading combustion features into a single-flange explosion-proof device for measuring oxygen, CO, and methane. Whether it's being used for oxygen trim control, CO monitoring, high combustible fuel runback control, or even a SIL2-rated startup permissive for methane, the TDLS Probe Type is capable of providing measurements for all of these functions in a single device.
Benefits
Reduced Installation and Maintenance Costs
- Single-flange design allows for installations where cross-duct TDLS technology was not feasible due to obstructions or accessibility issues
- Capability to make O2 + CO/CH4 Measurements with a single device up to 850°C
- Onboard diagnostics with 50 days of data and spectral storage ensure that minor issues can be identified before they become more serious problems
- Explosionproof/flameproof for installation in CID1/Z1 or CID2/Z2 areas
- HART and Modbus TCP come standard to maximize remote diagnostics and configuration capabilities with a single cable run
Reliability
- Reference Cell
Internal reference cell in the laser/detector module ensures peak locking
- Auto-gain
Auto-gain enables a wide signal range during dynamic process events
- Validation
Initiated manually, remotely, or automatically on a daily, weekly or monthly basis defined by the user
- SIL2 Certified
IEC61508 SIL designed & approved, SIL2 capability for single analyzer use, SIL3 capability for dual analyzer use.
Features
Single flange design reduces total installed cost
- Ideal for smaller fired assets or installation points where clear aperture cannot be achieved
- Reduced overall installed cost for additional nozzles, alignment services, or platform installation
Replacing of existing extractive gas sampling analyzer
- Reduced overall maintenance demand with no consumables and negligible drift (eliminates calibration)
- In-situ measurement removes sample lag time
