ABB TB84PH2000300 pH/ORP/pIon Transmitter

Description

ABB TB84PH2000300 pH/ORP/pIon Transmitter

The ABB TB84PH2000300 is a highly specialized, heavy-duty industrial instrument from ABB’s analytical measurement division. It is a premium pH/ORP (Oxidation-Reduction Potential) sensor assembly, designed to withstand extremely harsh, fouling, and corrosive process environments.

Product Detailed Description

The TB84PH2000300 belongs to ABB’s TB84 series of toroidal and sensor hardware. This specific model features a rugged, solid-state reference design rather than a traditional liquid-filled glass electrode. It utilizes a Next-Step solid-state reference system that is highly resistant to chemical poisoning and coating.

The heavy-duty body construction ensures long-term survivability in extreme chemical processes where standard laboratory or light-industrial pH probes would fail within days.

Technical Parameters

Product Advantages

• Solid-State Reference Protection: Unlike standard sensors that suffer from liquid junction plugging, the solid-state matrix eliminates the primary cause of pH sensor failure in industrial waste streams.
• Extreme Chemical Resistance: The outer body material provides superb resistance to aggressive chemicals, including strong acids, bases, and organic solvents.
• Integrated Temperature Compensation: Features an embedded RTD element, providing real-time temperature data to the transmitter for precise pH tracking as fluid temperatures fluctuate.
• Low Maintenance: The smooth, fouling-resistant surface design drastically reduces the frequency of manual cleaning and recalibration cycles.

Important Considerations & Precautions

• Hydration Required: The sensor glass tip must never be allowed to dry out. If stored or left offline, it must be kept in a proper storage solution (typically 4.0 pH buffer or KCl solution).
• Coating/Fouling Mitigation: While highly resistant, if used in heavy oil or scaling applications, the sensor must be periodically cleaned with an appropriate solvent (e.g., light acid for scaling, detergent for oils) without scratching the glass bulb.
• Cable Handling: The low-noise coaxial cable is highly sensitive. Do not route it next to high-voltage power cables or variable frequency drives (VFDs) to prevent signal noise. Do not splice the cable without a proper junction box.
• Calibration: Regular two-point calibration using certified buffer solutions (typically pH 4.01, 7.00, or 10.01) is essential to maintain industrial accuracy.

Product Applications

The TB84PH2000300 is built for demanding heavy industries:

• Chemical Manufacturing: Monitoring highly acidic or alkaline chemical reactions and neutralization loops.
• Pulp & Paper Processing: Used in bleaching towers and black liquor processing lines where harsh chemicals dominate.
• Wastewater Treatment: Monitoring industrial effluent, heavy metal precipitation, and neutralization tanks before environmental discharge.
• Mining & Refining: Slurry monitoring and ore leaching processes where abrasive materials and chemicals coexist.
• Power Generation: Flue Gas Desulfurization (FGD) scrubber systems to manage limestone slurry pH.
