Field of application
Liquisys CLM223 is a standard transmitter for all analog conductivity sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and calibration make configuration and operation fast and easy.
The Liquisys CLM223 transmitter works with all analog conductivity sensors in non-hazardous areas, for example in these industries and their utilities:
Chemicals
Food & Beverages
Life Sciences
Power &Energy
Water &Wastewater
Primaries & Metal
Liquisys CLM223 features the following protocols and interfaces:
0/4...20 mA
HART
PROFIBUS DP
PROFIBUS PA
Benefits
More operational safety: Continuous process check system, customized alarm configuration, calibration plausibility check.
Broad functionality: Conductivity, resistivity and concentration measurement, ultrapure water monitoring according to USP and EP.
Easy to operate and service: Intuitive user interface, easy calibration, direct access for manual contact control.
Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm or limit switch.
Fit for every application: Numerous extensions, such as P(ID) controller, timer, etc., allow for flexible adaption to all processes.
