Fits binary gas composition measurement where you need an XMTCpro thermal-conductivity analyzer with dual isolated 4–20 mA, Modbus, and spans from 0–1% to 0–100% class.
Key advantages
- Principle — Thermal conductivity binary gas analyzer (SIL 2 by design optional)
- Accuracy — ±2% of span; linearity ±1%; repeatability ±0.5%
- Response — 20 s for 90% step change
- I/O — Two isolated 4–20 mA; Modbus RS232/RS485
- Gases — H2/He/CO2/Ar in N2/air/O2 mixes per application table
Typical applications
- Hydrogen and helium binary gas monitoring.
- Inerting and process gas composition checks.
- Sites needing Modbus plus dual mA retransmission.
Selection guide
- Span — 0–1% to 0–100% or high-end spans (50–100% … 98–100%)
- Gas pair — Confirm thermal-conductivity contrast for the binary mix
- Temperature class — Standard –20…+50 °C vs high-temp –5…+65 °C
- SIL — SIL 2 by design option if required
Common mistakes
- Applying TC binary analysis to multi-component streams without a defined binary pair.
- Ignoring sample flow window (50–2,000 cc/min; 250 cc/min nominal).
- Omitting SIL option when the loop is safety-related.
When to RFQ / what to tell us
- Gas pair and span.
- Temperature class; SIL need; Modbus/mA use.
- Quantity and ship-to.
