8221 Conductivity Sensor
Brand: Burkert Fluid Control Systems
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 construction, these conductivity probes are suitable for use under demanding conditions in application sectors including food and 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. Contamination affects the measurements.
- probes based on the 4-electrode principle exclude polarization phenomena and are not sensitive to contamination. This clever design guarantees an excellent linearity over a wide conductivity range.
- Perfect for demanding applications in the hygienic industry (CIP and SIP compatible)
- Variants available for usage over a wide conductivity range
- Due to support of the most important process connections specific customer requests can be implemented
- Fits perfectly to our multipurpose transmitter/controller type 8619
