The Liquiline Compact CM72 transmitter is small and lightweight and is used together with Memosens digital sensors. It is the right choice for applications with limited installation space where multiparameter devices are not required. Combined with a sensor, it can be installed in most assemblies for even more convenient installation. The CM72 is ordered with preconfigured measuring parameters and measuring range, so it can be used directly after installation, with high safety and no operating errors.
Advantages
Small installation space required: the two-wire device can be installed inside the assembly without its own power supply.
Fast start-up: the CM72 has fixed settings, requires no commissioning and can be put into service quickly.
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.
On-site diagnostics: red/green LED indicators show the status of the transmitter and the connected sensor.
Suitable for all installation positions: the CM72 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 CM72 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 measuring parameters and measuring range are preset when the transmitter is ordered and cannot be changed later.
The two-wire instrument is equipped with the following interfaces:
4...20 mA
With numerous international explosion protection approvals, the CM72 can be used in hazardous areas, e.g. IECEx, ATEX and CSA.
