YOKOGAWA PR4A-T-10 RETRACTABLE CONDUCTIVITY SENSOR

Description:

The Yokogawa PR4A-T-10 Retractable Conductivity Sensor Assembly is used an in-line industrial fitting designed for continuous conductivity measurement in process systems. It features a titanium probe construction (PR4A-T series) for superior corrosion resistance in aggressive or high-purity applications. The retractable design allows safe insertion and removal of the sensor under pressure without shutting down the process, supporting maintenance, calibration, and replacement without system interruption. 

Applications:

The Yokogawa PR4A-T-10 is used in industrial environments for continuous online monitoring of conductivity in liquid processes. It is commonly deployed in water and wastewater treatment, chemical processing, power generation, and high-corrosion or high-purity systems. The retractable design allows maintenance, calibration, and sensor replacement without interrupting the process, ensuring system uptime and reliable measurement.
