3. Product Specifications
3.1 Measurement Principle
The XMTC-62-21 measures the concentration of a gas in a binary (or pseudo - binary) gas mixture. It does this by measuring the thermal conductivity of the sample gas and comparing it to the thermal conductivity of a selected reference gas. Based on this comparison, it provides a 4 - 20 mA signal proportional to the concentration of one of the gases in the mixture. This principle allows for highly accurate determination of gas composition in industrial applications.
3.2 Packaging and Installation
The transmitter can be packaged in weatherproof or explosion - proof enclosures, making it suitable for installation in various environmental conditions. It is designed to be installed as close as possible to the process sample point. This proximity to the sample source minimizes signal interference and ensures that the measurements are as representative as possible of the actual process conditions.
3.3 Signal Processing
Equipped with advanced signal processing algorithms, the XMTC-62-21 can adapt to changing operational conditions. It filters out noise and other unwanted signals, delivering consistent and reliable readings even when the temperature, pressure, or other environmental factors are fluctuating. This ability to handle variable conditions is crucial for maintaining the integrity of the data in industrial processes.
4. Features

This high level of precision is essential in industries where even small deviations in gas composition can have significant impacts on process efficiency and product quality.
- Wide Operating Temperature Range: With an operating temperature range from - 40 °C to + 125 °C, it can function effectively in extreme cold and hot industrial environments. This makes it suitable for use in a variety of industries, including those in harsh climates or where the process itself generates high or low temperatures.
- Fast Response Time: The response time of less than 0.5 seconds allows for real - time monitoring of changes in gas composition. In industrial processes, quick detection of changes is crucial for timely corrective actions, preventing potential accidents or inefficiencies.
- Robust Construction: Built with a durable and corrosion - resistant housing, it can withstand harsh industrial conditions, including exposure to chemicals, moisture, and vibrations. This robust construction ensures long - term reliability and reduces the need for frequent replacements or maintenance.
- Compact Design: The compact dimensions (approx. 14 cm x 10.5 cm x 3.7 cm) facilitate easy installation in tight spaces. This is beneficial in industrial settings where space may be limited, such as in control panels or on existing process equipment.
5. Usage and application areas
5.1 Purpose
The primary purpose of the GE XMTC-62-21 is to accurately measure the thermal conductivity of gas mixtures in industrial processes. By providing precise data on gas composition, it enables operators to optimize processes, ensure product quality, and maintain safety. For example, in a chemical reaction process where the ratio of reactant gases is critical, the XMTC - 62 - 21 can monitor the gas composition in real - time, allowing for adjustments to be made to maintain the correct reaction conditions.
5.2 Application Areas
- Chemical Processing: In chemical plants, the XMTC-62-21 is used to monitor the composition of gas streams in various chemical reactions. It helps in ensuring that the reactions proceed as expected, optimizing product yields, and preventing unwanted side reactions. For instance, in the production of petrochemicals, accurate measurement of gas mixtures can lead to more efficient refining processes.
- HVAC Systems: In heating, ventilation, and air - conditioning systems, the transmitter can be used to measure the composition of gases in air handling units. This information can be used to control ventilation rates, ensuring good indoor air quality. For example, by detecting the presence of certain gases, the system can adjust the fresh air intake to maintain a healthy environment.
- Power Generation: In power plants, especially those using gas turbines, the XMTC-62-21 is used to monitor the composition of fuel gases. Ensuring the correct gas composition is crucial for efficient combustion, which in turn affects the power generation efficiency and reduces emissions. It can also be used to detect any impurities in the fuel gas that could cause damage to the turbine.
- Water Treatment: Although mainly associated with gas measurement, in some water treatment processes that involve gas - liquid interactions (such as aeration processes), the XMTC-62-21 can be used to monitor the gas composition in the air or gas being introduced into the water. This helps in optimizing the treatment process and ensuring the proper removal of contaminants.
