Det-Tronics C7064E4012 Detector

Product Dimensions：

The Det-Tronics C7064E4012 is a high-performance Hydrogen Sulfide (H_2S) Gas Transmitter. It is a core component of the Det-Tronics gas detection lineup, specifically designed to withstand the harshest industrial environments while providing life-safety monitoring for toxic gas leaks.

Product Detailed Description

The C7064E4012 is an electrochemical sensor-based transmitter. It is housed in a rugged, explosion-proof enclosure (typically stainless steel or aluminum) and provides a standard 4–20 mA DC output proportional to the gas concentration. This specific model is calibrated for the detection of Hydrogen Sulfide, a highly toxic and corrosive gas common in industrial processes.

Technical Parameters

Product Advantages

• Superior Durability: The 316 stainless steel housing is designed for extreme offshore and petrochemical environments where salt spray and chemicals are present.
• Non-Intrusive Calibration: Many Det-Tronics transmitters allow for “one-man” calibration using a magnetic tool, meaning the enclosure does not need to be opened in hazardous areas.
• Long-Term Stability: The electrochemical cell is engineered to minimize “drift,” ensuring accurate readings over long periods and reducing the frequency of recalibration.
• Fault Diagnostics: The 4–20 mA output includes specific “under-range” levels (e.g., 3.8 mA or less) to signal a sensor fault or hardware failure to the controller.

Important Considerations & Precautions

• Sensor Life: Electrochemical sensors are “consumable” items. They typically have a lifespan of 2–3 years depending on the environment. Plan for periodic sensor cell replacement.
• Cross-Sensitivity: While optimized for H_2S, the sensor may respond to other gases (like Methyl Mercaptan). Consult the manual for cross-sensitivity data if other gases are present.
• Orientation: The transmitter should be mounted with the sensor pointing downward to prevent moisture or dust from accumulating on the sensor flame arrestor.
• Bump Testing: Regular “bump tests” (applying a known concentration of gas) are critical to verify that the gas path to the sensor is not obstructed by paint, grease, or debris.

Product Applications

The C7064E4012 is a standard choice for toxic gas monitoring in high-stakes industries:

• Oil & Gas Exploration: Monitoring for “sour gas” (H_2S) on drilling rigs and production platforms.
• Refineries: Protecting personnel near sulfur recovery units and hydrotreaters.
• Wastewater Treatment: Monitoring for H_2S buildup in sewers, wet wells, and sludge processing areas.
• Chemical Processing: Safety monitoring in facilities that use or produce sulfur-based compounds.
