Field of application
The Liquiline Compact CM82 is the smallest transmitter for Memosens sensors. Its slender housing measures only 11 cm long and 2 cm wide, including a connection to which you can attach your sensor directly, without a cable. Together with the sensor, it fits into most assemblies and couldn’t be easier to install. Via a uniquely secure Bluetooth connection, you can see all nearby CM82 measuring points on your tablets or smartphones and operate them conveniently from a distance.
Liquiline Compact CM82 can be used in all industries and their utilities and supports all sensors with the blue Memosens plug-in head:
pH sensors
ORP sensors
Conductivity sensors
Oxygen sensors
The loop-powered two-wire transmitter features the following protocols and interfaces:
4...20 mA
HART
Bluetooth
With its international explosion protection approvals, such as IECEx, ATEX, and CSA, the Liquiline Compact CM82 is suitable for hazardous area use.
Benefits
Easy operation:
Use your existing tablets and smartphones for operation and commissioning.Fast and reliable:
A secure Bluetooth connection allows you to check measuring points that are dangerous or difficult to access from a safe distance.Benefit from all the advantages of Memosens technology:
Memosens sensors offer you the safest data transmission, the highest measured value availability and total ease of use.Space-saving installation:
The two-wire device fits inside an assembly and does not require its own power supply.Suitable for all locations:
Whether your measuring point is exposed to dust, vapor, rain, snow, heat or cold, the CM82 will always be exactly the right transmitter for you.
