The Liquiline Compact CM82 transmitter is small and lightweight and is used together with Memosens digital sensors. The slim housing is only 11 cm long and 2 cm wide and features a connection interface for directly mounting the sensor without any cable. Combined with a sensor, it can be installed in most assemblies for even more convenient installation. Via a unique secure Bluetooth connection, users can view all nearby CM82 measuring points on a tablet or smartphone and operate them conveniently from a distance.
Advantages
Simple operation: operate and commission the instrument using existing tablets and smartphones.
Fast and reliable: via a secure Bluetooth connection, users can view all hazardous measuring points or remotely operate hard-to-reach installation points.
Full benefit of all the advantages of Memosens digital sensor technology: Memosens digital sensors provide the most secure data transmission, the highest measured value stability and are very convenient to use.
Small installation space required: the two-wire device can be installed inside the assembly without its own power supply.
Suitable for all installation positions: the CM82 transmitter is always the right choice, even if the measuring point has to withstand dust, water vapor, rain, snow, heat or extreme cold directly.
Application areas
The Liquiline Compact CM82 can be used in all industries and their utilities and allows connection of all sensors with a blue Memosens plug.
pH electrodes
ORP electrodes
Conductivity sensors
Dissolved oxygen sensors
Disinfectant sensors
The loop-powered two-wire transmitter supports the following communication protocols and interfaces:
4...20 mA
