EMD-485 Oxygen Transmitter | Product Specifications

Oxygen Transmitter:

The EMD-485 Oxygen Transmitter combines a compact electronic design with Southland Sensing’s precision electrochemical oxygen sensor technology. Designed primarily for OEM integration, the transmitter provides reliable and cost-effective trace or percent oxygen measurement in a flexible, easy-to-integrate package.

The EMD-485 is available with measurement ranges from 0–10 PPM through 0–100% O₂, with options including a local display, multiple oxygen sensor chemistries, and sensor housings for flow-through, direct-mount, and ambient monitoring applications.

The analog output is non-isolated and is designed for straightforward integration with compatible PLCs, data acquisition systems, and OEM control electronics. Applications requiring electrical isolation should incorporate appropriate external isolation or select an alternative Southland Sensing configuration with an isolated output.

Multiple configurations and customized OEM options are available. Refer to the ordering guide for available measurement ranges, sensor housings, display options, and oxygen sensor configurations.

電源要件

Input Power: 12 – 24 V DC
Current Draw: 40 mA Nominal

Oxygen Sensor Technology:

The oxygen sensors used with the EMD-485 are based on proven galvanic electrochemical fuel cell technology. All oxygen sensors are manufactured in-house by Southland Sensing Ltd. under a controlled quality program to provide consistent performance, accuracy, and long-term stability.

Multiple sensor chemistries are available to accommodate different process gas compositions. Standard sensors are designed for applications containing background gases such as hydrogen, helium, and hydrocarbons. Acid-resistant sensors are available for applications containing carbon dioxide and other acid gas backgrounds, including many natural gas streams.

Southland Sensing oxygen sensors are completely self-contained and require minimal routine maintenance, with no electrodes to clean or electrolyte to replenish.

Southland Sensing’s precision electrochemical oxygen sensor technology provides reliable oxygen measurement while maintaining long sensor life across a wide range of industrial and OEM applications.

Oxygen Sensors:

The EMD-485 is available with multiple oxygen sensor configurations to accommodate trace and percent oxygen measurement across a variety of process gas compositions.

TO2-1X PPM Oxygen Sensor: Trace Oxygen Analysis – Standard Applications
TO2-2X PPM Oxygen Sensor: Trace Oxygen Analysis – Acid Gas Applications
PO2-160 Percent Oxygen Sensor: Percent Oxygen Analysis – Standard Applications
PO2-24 Percent Oxygen Sensor: Percent Oxygen Analysis – Acid Gas Applications

Oxygen sensors should be periodically calibrated to maintain measurement accuracy. Southland Sensing recommends calibration approximately every 2–3 months, or at an interval appropriate for the specific application and operating conditions.

The sensors provide excellent linearity and can be conveniently calibrated using ambient air when appropriate. For applications requiring greater calibration accuracy or traceability, a certified span gas can be used.
