Type 8221 - Conductivity sensor for hygienic applications

Type Description

The 8221 hygienic conductivity probes are used to determine electrical conductivity in a wide range of pure or concentrated liquids. Due to their hygienic and robust design, these conductivity probes are suitable for use in various application sectors, including the food & beverage, pharmaceutical, biotechnology and chemical industry. Two technologies of conductivity probes are available: • Probes based on the 2-electrode principle are suited for measurements in liquids, especially (ultra) pure water. Contaminations affect the measurements. • Probes based on the 4-electrode principle exclude polarisation phenomena and are not sensitive to contamination. The clever design guarantees an excellent linearity over the entire measurement range. An integrated temperature sensor (Pt1000) is a standard feature of all versions. The probe has to be connected to the multiCELL transmitter/controller Type 8619.
