Product Description

The OTB122 is a specialized Explosion-Proof Termination Box (also referred to as a Connection or Junction Box) manufactured by Zellweger Analytics (now part of the Honeywell Analytics group). It is primarily used in conjunction with gas detection systems, such as the famous Searchline Excel Open Path Gas Detector.

The code BAS98ATEX3008X refers to the specific ATEX Certification number, confirming that this hardware is designed and tested for safe operation in potentially explosive atmospheres (Hazardous Areas).

Product Parameters

Key Product Advantages

• High-Level Safety: Certified under ATEX for Zone 1 and Zone 2 applications, ensuring that any internal spark or explosion is contained within the box and will not ignite the surrounding atmosphere.

• Corrosion Resistance: Designed for harsh offshore and onshore environments, with a robust coating resistant to salt spray and industrial chemicals.

• Ease of Installation: Provides a spacious interior for wiring, making it easier for technicians to terminate thick, shielded armored cables common in industrial gas detection.

• Seamless Integration: Specifically engineered to match the electrical and mounting requirements of Zellweger/Honeywell gas transmitters (like the Searchline Excel).

Critical Usage Notes & Precautions

1. Seal Integrity: The “X” in the ATEX certificate number often indicates “Special Conditions for Safe Use.” This usually requires that all unused cable entries must be sealed with certified Ex d blanking plugs.

2. Thread Maintenance: Flameproof paths (the threads of the cover and entries) must be kept clean and lightly lubricated with a non-setting, non-metallic grease. Do not paint over the gap between the cover and the body.

3. Grounding: Ensure the internal and external earth (ground) terminals are connected to the plant’s earthing system to prevent static buildup and ensure EMI shielding.

4. Opening the Unit: NEVER open the termination box while the circuit is live unless the area is known to be non-hazardous (Hot Work Permit required).

Product Applications

The OTB122 is a critical component in safety-instrumented systems:

• Oil & Gas Refineries: Used to terminate wiring for infrared open-path gas detectors monitoring for hydrocarbon leaks.

• Offshore Platforms: Provides a weather-proof and explosion-proof hub for gas detection signals on drilling rigs.

• Chemical Plants: Protecting electrical connections for toxic gas sensors in areas where flammable vapors are present.

• Pipeline Monitoring: Acting as the junction point for long-distance safety loops in gas compressor stations.
