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 design and the robust layout, these conductivity probes are suitable for use under demanding conditions in application sectors including food & beverage, pharmaceutical, biotechnology and the general 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 polarization phenomena and are not sensitive to contamination. The clever design guarantees an excellent linearity over a wide conductivity range. An integrated temperature sensor (Pt1000) is a standard feature of all versions and can be used for temperature compensation. The probe has to be connected to the multiCELL transmitter/controller Type 8619.
