Yokogawa SC42-SP24 SC4A Conductivity Sensor

The measurement of specific conductivity in aqueous solutions is becoming increasingly important for the determination of impurities in water or the concentration measurement of dissolved chemicals. The accuracy of the measurement is strongly influenced by temperature variations, polarisation effects at the surface of the contacting electrodes, cable capacitances, etc. 

Yokogawa provides sensors for pure water systems, general applications with a 2-electrode design and applications involving high concentrations of chemicals with a 4-electrode design. 

To install conductivity sensors in a permanent or semi-permanent location, Yokogama offers wide a range of flow and immersion fittings. A high degree of standardisation simplifies mounting, servicing and removal or replacement of the sensors.

 Included are flow fittings and subassemblies for in-line or direct mounting of conductivity sensors in piping systems. 

The immersion fittings are designed for tanks, open vessels or drains. PVC and stainless steel construction materials suit most process conditions, regarding chemical resistance, pressure and temperature specifications. 

The fiitings of stainless steel might be used in sanitary applications.
