ABB TB47 High-Pressure Hot-Tap Type Stainless Steel Electrodes

Overview

The ABB TB47 high-pressure, hot-tap type stainless steel electrodes are engineered to provide robust and precise conductivity measurement in industrial liquid analysis applications. Designed with a hot-tap extraction housing, these electrodes can be inserted or removed from process lines or vessels without interrupting the process — enhancing safety and reducing system downtime in critical operations. 

Constructed from corrosion-resistant 316 stainless steel, the TB47 electrodes withstand harsh process environments and high operating conditions. Their rugged build and high-pressure capability make them suitable for use in chemical, power generation, pulp and paper, and other industrial applications where reliable measurement and long service life are essential. 

Key Features & Technical Details

• Hot-Tap Step-Insertable Design: Allows insertion/removal without process interruption, improving maintenance efficiency. 

• High Pressure Capability: Designed for elevated service pressures beyond standard hot-tap sensors. 

• 316 Stainless Steel Construction: Corrosion-resistant construction enhances durability in aggressive process environments. 

• Maximum Operating Temperature: Up to 200 °C (392 °F). 

• Maximum Operating Pressure: Up to 2,068 kPa (20.68 bar / 300 psi). 

• Purgeable Extraction Housing: Enables safer and simpler extraction or retraction. 

• Automatic Temperature Compensation: Built-in for consistent conductivity readings. 

These features make the TB47 electrodes a reliable choice for continuous liquid conductivity monitoring. 

Industrial Applications

The ABB TB47 electrodes are widely deployed in diverse industrial settings, including:

• Chemical processing plants requiring accurate conductivity measurement

• Power and utility plants for boiler feedwater and condensate monitoring

• Pulp & paper production for process liquid measurement

• Water and wastewater treatment systems requiring precise sensor performance

• Refinery and petrochemical processing environments with high operating pressures 

Their hot-tap design enhances worker safety and minimizes maintenance downtime across these critical applications. 

Installation & Integration

The ABB TB47 electrodes are installed into a compatible hot-tap extraction housing with ball valve isolation. This setup allows operators to safely isolate the process before sensor extraction or insertion. Integration with analytical transmitters, controllers, or conductivity measurement systems is straightforward, requiring standard industrial process connections and purge line configurations.
