Technical Information
Liquiline Compact CM82
Configurable multiparameter transmitter for
Memosens sensors
Space-saving transmitter for monitoring and
controlling processes in industry and the
environmental sector
Application
The CM82 can be used in all sectors and by plant manufacturers in these sectors and
supports all sensors with the blue Memosens plug-in head:
• pH, ORP and pH-ORP combined electrodes
• Conductive conductivity
• Oxygen
Direct connection to PLC via:
• 4 to 20 mA
• HART
• Bluetooth® LE interface for commissioning and maintenance
Your benefits
• Space-saving installation and storage:
– The two-wire device fits into an assembly and does not require a separate power
supply.
– Minimum inventory
• Maximum safety:
Tried and trusted Memosens technology
• Easy operation
– Use your existing tablet and smartphone for operation and commissioning.
– Standardized operating concept across all devices from the Liquiline platform
• Fast and reliable
A reliable Bluetooth® LE connection allows you to check measuring points that are
dangerous or difficult to access from a safe distance.
• Suitable for all locations
Regardless of whether your measuring point is exposed to dust, steam, rain, snow,
heat or cold, the CM82 is always exactly the transmitter you need!

Measuring system
The overview shows examples of measuring systems. Other sensors and assemblies can be ordered
for conditions specific to your application (www.endress.com/products).
A complete measuring system comprises:
• Liquiline compact transmitter
• Sensors with Memosens technology
• Assemblies to suit the sensors used

Reliability
Communication and data processing
Types of communication:
• 4 to 20 mA
• HART fieldbus
• Bluetooth® LE wireless technology (optional)
The device drivers available make it possible to perform a basic setup and display measured
values and diagnostics information via the fieldbus. Full device configuration is possible via the
fieldbus and Bluetooth.
Dependability
Memosens
Memosens makes your measuring point safer and more reliable:
• Non-contact, digital signal transmission enables optimum galvanic isolation
• No contact corrosion
• Completely watertight
• Sensor can be calibrated in a lab, thus increasing the availability of the measuring point in the
process
• 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
– Hours of operation at high temperatures
– Number of steam sterilizations
– Sensor condition

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 against the tables defined in the standards. An alarm
is triggered if the limit value is exceeded. Furthermore, it is also possible to configure an early
warning alarm that signals undesired operating states before they occur.
Safety Safe signal transmission via Bluetooth® LE
Signal transmission via Bluetooth® wireless technology uses a cryptographic technique tested
by the Fraunhofer Institute.
Security levels for Endress and Hauser Bluetooth infrastructure:
• Protocol: High
• Algorithms: High
Measured against:
• the security objectives, e.g. confidentiality, integrity, availability, etc.
• the risk analysis, e.g. key distribution, authentication, password recovery, etc.
• the attack model, e.g. motivation for attack, time required, expertise in electronics, etc.
• the weak-point analysis
For comparison: The general Bluetooth standard is classified as "Low".
Protection against unauthorized access:
• Password-protected
• Without the SmartBlue app, the device is not visible via Bluetooth® wireless technology.
• Only one point-to-point connection is established between a sensor and a smartphone or tablet.

• The Bluetooth® wireless technology interface can be disabled via SmartBlue.
• Bluetooth® is optional. It can be ordered with this functionality enabled.
If ordered with Bluetooth® disabled, Bluetooth® can be enabled at a later stage by means of an
activation code (accessory kit) linked to the serial number.
• A disabled Bluetooth® interface can be re-enabled only via HART.

IT security
Our warranty is valid only if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertent
changes to the settings.
IT security measures, which provide additional protection for the device and associated data transfer,
must be implemented by the operators themselves in line with their security standards.
