YOKOGAWA SC41-SP34 CELL CONDUCTIVITY SENSOR SC41SP34

Description:

The Yokogawa SC41-SP34 Conductivity Sensor is used a contacting (electrode-type) conductivity cell designed for continuous measurement of liquid conductivity in industrial processes. It uses a 2-electrode design with an integrated temperature element for accurate, temperature-compensated readings. Built with stainless steel and industrial-grade materials, it is suitable for low-conductivity applications such as pure water, boiler feedwater, and chemical processes.

Applications:

The Yokogawa SC41-SP34 is used in industrial environments for continuous monitoring of conductivity in liquid processes. It is commonly deployed in water and wastewater treatment, power generation (boiler and condensate monitoring), semiconductor and pharmaceutical systems, and chemical processing. The sensor enables real-time measurement of ionic concentration to maintain process quality and system efficiency.
