Selection Guide
Use the following criteria to select the correct gas analyzer module for your application:
- Step 1 – Identify your DCS platform: Confirm TDC 3000 vs. TPS vs. Experion PKS architecture.
- Step 2 – Check the suffix revision: The -175 suffix denotes a specific hardware/firmware revision. Mismatched revisions may cause communication faults.
- Step 3 – Verify slot type: Confirm card cage slot type (LCN vs. UCN) and available backplane power.
- Step 4 – Define gas species: Ensure the module supports the target gas components (O₂, CO, CO₂, NOx, etc.).
- Step 5 – Confirm certifications: For hazardous area installations, verify ATEX/IECEx zone classification.
- Step 6 – Request a quote: Contact support@konmask.com with your system details for a tailored recommendation.
