The Panametrics XMTCpro is a compact and robust online thermal conductivity transmitter designed for continuous measurement of gas concentrations in binary mixtures. It is SIL 2 capable by design, incorporating real-time error detection for enhanced process safety . The transmitter is ideally suited for industrial applications requiring reliable analysis of gases such as hydrogen (H2), carbon dioxide (CO2), methane (CH4), and helium (He) in various carrier gases like nitrogen or air .

The XMTCpro features an ultra-stable thermal conductivity sensor housed in a rugged, contamination-resistant measuring cell with no moving parts, ensuring reliability in harsh and vibrating environments . Its modular construction allows for fast and easy servicing, including field calibration and replacement of the measuring cell with a pre-calibrated spare . The transmitter includes an integrated high-contrast, multi-parameter display for local data viewing and an intuitive user interface, making it easy to configure and use .

For flexible system integration, the XMTCpro provides two isolated, field-programmable 4-20 mA analog outputs and MODBUS digital communication (RS232/RS485) for configuration and data access . It requires 24 VDC power and is available in both weatherproof (aluminum) and explosion-proof (stainless steel) enclosures to suit diverse installation environments . A sample conditioning system, available from Panametrics, is required to ensure optimal sample delivery at the correct temperature, pressure, and flow rate . The XMTCpro is suitable for a wide range of binary gas applications, including hydrogen-cooled generator monitoring, process control in chemical plants, and purity monitoring in air separation units .
