Gas Transmitters: Continuous Gas Monitoring for Safety and Control

Pioneer offers reliable gas transmitters for continuous monitoring of specific gases in various industrial, commercial, and environmental applications. These transmitters provide accurate real-time gas concentration data and transmit signals to control systems, alarms, or data loggers, ensuring safety and process efficiency

The Importance of Continuous Gas Monitoring

• Worker Safety : Protecting personnel from exposure to toxic or flammable gases.
• Process Control : Maintaining optimal gas concentrations for efficient and safe operation.
• Leak Detection : Providing early warning of gas leaks, preventing accidents and minimizing losses.
• Environmental Monitoring : Tracking emissions and ensuring compliance with regulations.
• Combustion Control : Optimizing combustion processes for efficiency and safety.

Types of Gas Transmitters

• Toxic Gases: CO, H2S, SO2, NO2, NH3, Cl2, and many others.
• Combustible Gases: Methane (natural gas), propane, butane, hydrogen, and other flammable gases (often measured as %LEL - Lower Explosive Limit).
• Oxygen (O2): Monitoring oxygen levels for safety (deficiency or enrichment).
• Refrigerant Gases: Detecting leaks of refrigerants in HVAC/R systems.
• Volatile Organic Compounds (VOCs): Monitoring VOC levels for indoor air quality and industrial hygiene.

Gas Sensor Technologies

• Electrochemical Sensors: Use a chemical reaction to generate an electrical current proportional to the gas concentration. Common for toxic gases.
• Catalytic Bead Sensors (Pellistors): Use a catalyst to oxidize combustible gases, measuring the resulting temperature change. Common for %LEL measurements.
• Infrared (IR) Sensors: Measure the absorption of infrared light by specific gases. Often used for CO2, hydrocarbons, and refrigerants.
• Photoionization Detectors (PIDs): Use ultraviolet light to ionize VOCs, measuring the resulting current.
• Semiconductor (Metal Oxide) Sensors: Use a metal oxide that changes resistance in the presence of certain gases.

Key Features and Considerations

• Target Gas: Select a transmitter designed for the specific gas you need to monitor.
• Measurement Range: Choose an appropriate range for your application.
• Accuracy and Sensitivity: Consider the required accuracy and detection limits.
• Output Signal: Typically 4-20 mA, 0-10 V, or digital communication protocols (e.g., Modbus, HART).
• Environmental Conditions: Temperature, humidity, and pressure can affect sensor performance.
• Hazardous Area Classification: If the transmitter will be used in a hazardous area, ensure it is appropriately certified (e.g., ATEX, IECEx).
• Calibration: Gas transmitters require periodic calibration to maintain accuracy.
