Liquisys M CLM223 is a transmitter for conductivity/resistivity measurement. It is suitable for conductive and inductive sensors. Liquisys M is available as panel-mounted housing (CLM223) or field housing (CLM253).
The modular design of the Liquisys M CLM223/253 allows easy adaption of the transmitter to a variety of customer requirements. Starting with the basic version for "measurement and alarm generation", the transmitter can be equipped with additional software and hardware modules for special applications. These modules can also be retrofitted as required.
Benefits:
Field or panel-mounted housing
Universal application

Plus package:
- User defined current output characteristics
- Automatic cleaning trigger on alarm or limit violation
- Ultrapure water monitoring acc. to USP (United States Pharmacopeia) and EP (European Pharmacopoeia) (conductive)
- Polarisation detection (conductive)
- Concentration measurement
- Temperature compensation via table
- Process Check System (PCS): live check of the sensor
- Adaptive calibration with installation factor (inductive)
HART® or PROFIBUS-PA/-DP
2nd current output for temperature, main measured value or actuating variable
Current input for flow rate monitoring with controller shut off or for feedforward control
