Dependability
Reliability Memosens
Memosens makes your measuring point safer:
• No-contact, digital signal transmission allows optimum galvanic isolation
• No contact corrosion
• Completely watertight
• Sensors can be calibrated in a lab, which increases the availability of measured values
• Predictive maintenance thanks to recording of sensor data, e.g.:
– Total hours of operation
– Hours of operation with very high or very low measured values
– Operating hours at high temperatures
– Number of steam sterilizations
– Sensor status
Quick Setup
To the first measured value within 1 minute
Once you have set up the few parameters in the Quick Setup menu, the measuring point is ready to
measure. The first measured value is reliably displayed.

Process Check System (PCS): Life check
This function is used to check the measuring signal for stagnation. An alarm is triggered if the
measuring signal does not change over a certain period (several measured values). The reason for such

Sensor Condition Check (SCC, pH only)
This function monitors the electrode status and the degree of electrode aging. The status is displayed
with the messages "SCC electrode condition bad" or "SCC electrode condition sufficient". The status of
the electrode is updated after every calibration.
Sensor Check System (SCS, pH only)
The Sensor Check System monitors the pH glass resistance or reference resistance (for analog and
combined sensors only), thus indicating possible incorrect measurements that may occur as a result of
damage to or clogging of the pH electrode.
In addition, the SCS detects glass breakage in the case of classic glass electrodes as well as leaks in the
case of ISFET sensors.
Polarization monitoring (conductivity only, conductively measured)
Polarization effects in the boundary layer between the sensor and the measuring solution limit the
measuring range of conductive conductivity sensors.
The transmitter can detect and report polarization effects using an intelligent signal evaluation
process.
United States Pharmacopeia, USP and European Pharmacopeia, EP (conductivity only)
The requirements for ultrapure water in the pharmaceutical industry are determined primarily by the
American USP and European EP.
The transmitter complies with USP/EP requirements for conductivity measuring systems:
• Exact temperature measurement at the place of conductivity measurement
• Simultaneous display of uncompensated conductivity values and temperature is possible
• Display resolution 0.01 μS/cm
• Exact factory calibration of the transmitter with traceable precision resistance (optional)
• Exact adjustment of sensors in the factory as per ASTM D 1125–91 or ASTM D 5391–99 (optional)
• Temperature-dependent measured value monitoring as per USP and EP.
The limit functions for pharmaceutical water are implemented in the "Advanced" software package in
accordance with USP and EP: For conductivity measurements, the limit functions for pharmaceutical
water are implemented in the software in accordance with USP and EP:
• Water for Injection (WFI) as per USP <645> and EP
• Highly purified water (HPW) as per EP
• Purified water (PW) as per EP
The uncompensated conductivity value and the temperature are measured for the USP/EP limit
functions. The measured values are compared with the tables set down in the standards. An alarm is
triggered if the limit value is exceeded. In addition, a prealarm can be set that flags undesirable
operating statuses before they occur.

Liquiline M CM42
Application-optimized calibration models (oxygen)
In separate functions, the transmitter allows process-adjusted zero point sensor calibration or sensor
calibration via the slope.
There are different calibration models for this, ranging from simple slope calibration in air that is
saturated with water vapor to slope calibration with input of the absolute air pressure and relative
humidity at the measuring location.
The latter model allows in-process calibration during operation as well as during sterilization and
cleaning.
The number of calibrations and sterilizations are tracked separately for the sensor and membrane cap.
The relevant counter can be reset if the membrane cap is replaced.

Safety User administration ("Advanced" only)
To avoid unscheduled changes to the measuring point, the device features a user administration
function.
You need to log on as an Expert to switch on the user administration function. The first time you log
onto the device, you will therefore be asked to enter a password (the "Admin" user name is already
entered).
The user administration function makes two different modes available in the Advanced version:
Roles
• There are 3 fixed user roles (Expert, Maintenance, Operator).
• "Experts" always have all the rights. "Operator" is the role with the least amount of rights.
• Each role has its own individual password. This password can be changed.
• No other user roles can be created.

• You can create and manage a maximum of 15 user accounts.
• You need to be logged on as an "Expert" to be able to manage accounts.
• In each user account you specify the user name and the password and assign the new user one of 3
user roles (Operator, Maintenance and Expert).
• Multiple user accounts with the "Expert" role are possible.
SIL
A TÜV-approved SIL2 version of the Liquiline M CM42 is also available (CM42-M* only, without
HART).
