ABB TB556J1E50T20 pH Electrode: Precision for Demanding Process Control

Accurate and reliable pH measurement is critical in countless industrial processes, from water treatment to chemical manufacturing. The ABB TB556J1E50T20 pH electrode stands out as a robust solution engineered for challenging environments requiring high performance and minimal maintenance.

Designed specifically for pressurized installations up to 6 bar (87 psi), this electrode excels in applications where direct insertion into pressurized lines or vessels is necessary, eliminating the need for complex bypass systems. Its sturdy glass body withstands demanding conditions, while the integrated Pt1000 temperature sensor (denoted by "J1" in the model) provides essential compensation for temperature variations, ensuring measurement accuracy across its operating range (-5 to 80°C / 23 to 176°F).

A key advantage is its gel-filled electrolyte system ("E"). Unlike traditional liquid-filled electrodes requiring frequent refilling, the TB556J1E50T20 utilizes a maintenance-free polymeric gel electrolyte. This significantly reduces upkeep, minimizes the risk of contamination, and enhances long-term stability – crucial factors for continuous process monitoring and reduced operational costs.

The electrode features a standard 12 mm diameter body ("50") suitable for common process fittings. It comes equipped with a 2-meter integral PUR cable ("T20"), terminated with a dedicated connector for seamless integration with compatible ABB TB550 series transmitters. This plug-and-play compatibility simplifies installation and setup.

The ABB TB556J1E50T20 is ideal for sectors like power generation (boiler feedwater, condensate), chemical processing, pulp & paper, and wastewater treatment. Its combination of pressurized capability, integrated temperature sensing, gel electrolyte reliability, and transmitter compatibility makes it a dependable choice for maintaining precise pH control in critical industrial loops where accuracy and uptime are paramount.
