ENDRESS+HAUSER  CLS82D-AAGAA

For measurements where very diverse conductivities must be measured by one measuring system.

Typical applications include:

• Phase separations
• Chromatography
• Fermentations
• CIP monitoring in small pipes
• Ultrafiltration

• High measuring accuracy as cell constant is individually measured
• Quality certificate stating the individual cell constant
• Hygienic process connections for installation in pipes or flow vessel
• IP68 protection
• Easy to clean thanks to electropolished surfaces
• Can be sterilized up to 140 °C (284 °F)
• Stainless steel 1.4435 (AISI 316L) meets the highest demands of the pharmaceutical industry
• The entire sensor is EHEDG- and 3A-certified
• FDA conformity

• Maximum process safety thanks to non-contact, inductive signal transmission
• Data security thanks to digital data transmission
• Very easy to use as sensor data saved in the sensor
• Recording of sensor load data in the sensor enables predictive maintenance

The measuring cell has four electrodes. An alternating current is applied via the outer electrode pair. At the same time, the voltage applied is measured at the two inner electrodes. The electrolytic conductivity between the electrodes can be reliably established based on the measured voltage and the current flow caused by the liquid's resistance. The advantage of this technology compared to traditional two-electrode sensors is that electrochemical effects at the live electrodes are suppressed by the two additional voltage measuring electrodes.

A complete measuring system consists of the following components at least:

• Conductive conductivity sensor CLS82D
• A transmitter, e.g. Liquiline CM44x
• A Memosens data cable CYK10
