The GE Panametrics XMTC‑62‑21 is a microprocessor‑based, 2‑port thermal conductivity transmitter engineered for continuous online measurement of binary gas mixtures. Designed for zero‑based applications, the XMTC‑62‑21 uses a sealed reference gas (air or N₂) within its factory‑calibrated chamber. Featuring ultra‑stable glass‑coated thermistors and a temperature‑controlled measuring cell (55°C standard), the XMTC‑62‑21 delivers excellent zero/span stability while resisting contamination and flow variations. With no moving parts and modular construction, the XMTC‑62‑21 withstands shock and vibration in harsh industrial environments and supports fast, easy field calibration, making it an ideal solution for long‑term, maintenance‑reducing gas analysis.
Metals industry – H₂ concentration in heat treat furnace atmospheres
Electric power generation – H₂ purity monitoring in generator cooling systems
Gas production – Purity verification for argon, hydrogen, nitrogen, helium
Chemical / petrochemical – H₂ in ammonia synthesis, methanol production, chlorine plants
Food industry – CO₂ in fermentation processes
Steel industry – H₂ in blast furnace top gas
Petroleum industry – H₂ in hydrocarbon streams
Ultra‑stable glass‑coated thermistors – Excellent zero and span stability with minimal drift.
Temperature‑controlled measuring cell – 55°C standard (70°C optional) eliminates ambient temperature effects.
2‑port sealed reference gas configuration – Ideal for zero‑based ranges (air or N₂ as background gas).
No moving parts – Withstands shock, vibration, and contamination in demanding industrial environments.
Modular construction – Plug‑in measuring cell can be replaced with pre‑calibrated spare in minutes.
Wide‑distance transmission – Up to 4000 ft (1200 m) using inexpensive unshielded cable.
Hazardous area certified – ATEX, IECEx, FM, CSA certified for Zone I and Division 1.
Push‑button calibration – Single or dual gas calibration with IDM™ software.
Continuously measures gas concentration – Monitors thermal conductivity of a sample gas against a sealed reference gas (air or N₂).
Provides linear 4‑20 mA output – Proportional to the concentration of the target gas (e.g., H₂, He, CO₂, CH₄).
Allows digital configuration & calibration – RS232 interface for PC‑based setup and data retrieval via IDM™ software.
Offers field‑replaceable measuring cell – Pre‑calibrated spare cell can be installed in minutes.
Supports fault detection – Real‑time error handling for drift, over/under range conditions.
Q1: What does the XMTC-62-21 measure?
A1: The XMTC‑62‑21 measures the concentration of a target gas (e.g., H₂, He, CO₂, CH₄) in a binary or pseudo‑binary gas mixture, providing a 4‑20 mA output proportional to that concentration.
Q2: What is the difference between the 2‑port and 4‑port XMTC?
A2: The XMTC‑62‑21 is a 2‑port transmitter with a factory‑sealed reference gas (air or N₂), intended for zero‑based ranges. The 4‑port version uses a flowing reference gas for zero‑suppressed ranges and special applications.
Q3: Does the XMTC-62-21 require a sample system?
A3: Yes. A sample system is mandatory to deliver a clean, dry sample at atmospheric pressure and a nominal flow rate of 0.5 SCFH (250 cc/min).
Q4: How often does the XMTC-62-21 need calibration?
A4: Recalibration is typically required every 2 to 6 months, depending on application, desired accuracy, and gas cleanliness. The unit supports push‑button field calibration.
Q5: Is the XMTC-62-21 approved for hazardous areas?
A5: Yes. The XMTC‑62‑21 is available in explosion‑proof versions certified to ATEX, IECEx, FM, and CSA standards for Zone I and Division 1 locations.
