Technical Information
Condumax CLS16D/CLS16
Hygienic conductivity sensors, analog or digital
with Memosens technology
Cell constant k = 0.1 cm
Application
Measurement in pure and ultrapure water range:
• Monitoring of ion exchangers
• Reverse osmosis
• Distillation
• Electrodeionization
• WFI (water for injection) in the pharmaceutical industry
Sensors with temperature probes are used in conjunction with conductivity
measuring devices that support automatic temperature compensation:
• Liquiline CM442/CM444/CM448 (only CLS16D)
• Liquiline CM42
• Liquiline CM14 (only CLS16D)
• Liquisys CLM223/253 (only CLS16)
• Mycom CLM153 (only CLS16)
The resistivity in MΩ · cm can also be measured using these transmitters.
Your benefits
• High measuring accuracy as cell constant is individually measured
• Hygienic process connections for installation in pipes or flow vessel
• With plug-in head (IP68) or fixed cable (IP67)
• Easy to clean thanks to electropolished surfaces
• Sterilizable up to 150 °C (302 °F)
• Quality certificate stating the individual cell constant
• Certified according to EHEDG, Document 8
• Certificate according to United States Pharmacopeia Class VI Part 87 and 88
(optional)
• Inspection certificate EN 10204 3.1 (optional)
Other advantages of Memosens technology
• Maximum process safety owing to non-contact, inductive signal transmission
• Data security thanks to digital data transmission
• Very easy to use as sensor data saved in the sensor
• Predictive maintenance possible as sensor load data logged in the sensor

Measuring principle
Measuring system
Conductivity of liquids is determined with a measuring
arrangement where two electrodes are located in the
medium. An alternating voltage that causes a current
to flow through the medium is applied at these
electrodes. The electrical resistance, or its reciprocal
value - conductance G - is calculated based on Ohm's
law. The specific conductance κ is determined from the
conductance value using the cell constant k, which
depends on the sensor geometry.

AC Alternating voltage source
I Current intensity measurement
U Voltage measurement
A complete measuring system comprises the following components at least:
• The conductively measuring conductivity sensor CLS16D or CLS16
• A transmitter, e.g. Liquiline M CM42
• A measuring cable, e.g. Memosens data cable CYK10 or CPK9 for analog sensors

Communication and data processing (only CLS16D)
Communication with the transmitter
Always connect digital sensors with Memosens technology to a transmitter with Memosens
technology. Data transmission to a transmitter for analog sensors is not possible.
Digital sensors are able to store the following system data in the sensor
• Manufacturing data
– Serial number
– Order code
– Date of manufacture
• Calibration data
– Calibration date
– Cell constant
– Delta cell constant
– Number of calibrations
– Serial number of the transmitter used for the last calibration
• Application data
– Temperature application range
– Conductivity application range
– Date of first commissioning
– Maximum temperature value
– Hours of operation at high temperatures
Reliability
Maintainability
Integrity
Dependability (only CLS16D)
Memosens technology digitizes the measured values in the sensor and transmits the data to the
transmitter using a non-contact connection that is free from potential interference. The result:
• Automatic error message if sensor fails or connection between sensor and transmitter is
interrupted
• Immediate error detection increases measuring point availability
Easy handling
Sensors with Memosens technology have integrated electronics that allow for saving calibration data
and further information such as total hours of operation and operating hours under extreme
measuring conditions. Once the sensor has been connected, the sensor data are transferred
automatically to the transmitter and used to calculate the current measured value. As the calibration
data are stored in the sensor, the sensor can be calibrated and adjusted independently of the
measuring point. The result:
• Easy calibration in the measuring lab under optimum external conditions increases the quality of
the calibration.
• Pre-calibrated sensors can be replaced quickly and easily, resulting in a dramatic increase in the
availability of the measuring point .
• Maintenance intervals can be defined based on all stored sensor load and calibration data and
predictive maintenance is possible.
• The sensor history can be documented on external data carriers and evaluation programs at any
time. Thus, the current application of the sensors can be made to depend on their previous history.
With inductive transmission of the measured value using a non-contact connection, Memosens
guarantees maximum process safety and offers the following benefits:
• All problems caused by moisture are eliminated.
– Plug-in connection free from corrosion
– Measured value distortion from moisture is not possible.
– The plug-in system can even be connected under water.
• The transmitter is galvanically decoupled from the medium.
• EMC safety is guaranteed by screening measures for the digital transmission of measured values.
