Product Overview
E+H CLM223 Panel-Mounted Conductivity Transmitter Controller
CLM223-CD0005
Designed for continuous conductivity, resistivity, and concentration measurement in industrial water and process applications. Basic measurement unit can be easily retrofitted with optional fieldbus (HART/PROFIBUS), PID controllers, and extra limit relays. Integrated continuous Process Check System (PCS) and plausibility checks ensure live sensor diagnostics and customized alarm configuration.Compact 96x96 mm panel housing, intuitive two-line backlit display, and simple 2-point calibration.Works seamlessly with all standard analog conductive and inductive conductivity sensors.
The CLM223-CD0005 Panel-Mounted Conductivity Transmitter is a compact, 4-wire liquid analyzer engineered for precise measurement of conductivity, resistivity, and chemical concentration in demanding industrial environments. Built with a modular field-proven design, the CLM223 series provides exceptional process reliability and long-term stability across municipal water treatment, pharmaceutical ultrapure water monitoring, and chemical processing utilities.
With its continuous Process Check System (PCS), the instrument active-monitors connected sensors, immediately alerting operators to sensor fouling, calibration drift, or cable degradation—minimizing unpredicted downtime and ensuring strict process compliance.
Supports conductive and inductive measurement principles. Displays values in conductivity (µS/cm, mS/cm), resistivity (MΩ·cm), or concentration percentage (%, ppm, mg/L, TDS).
Built-in calculation algorithms compliant with USP (United States Pharmacopeia) and EP (European Pharmacopoeia) standards for Water for Injection (WFI) and Purified Water (PW).
Supports Pt100, Pt1000, and NTC 30K sensors with user-configurable temperature coefficient tables for ultimate accuracy.
Integrated Chemoclean automatic cleaning function triggered by system alarms or timer thresholds to drastically reduce manual maintenance frequency.
Frequently Asked Questions
Q1: Can this transmitter be integrated into our existing PLC / SCADA system?
A: Yes. The CLM223 features standard 0/4-20mA analog outputs. Additionally, it supports digital fieldbus communication protocols such as HART and PROFIBUS PA/DP for seamless integration into centralized control systems.
Q2: Does the CLM223 support automatic temperature compensation?
A: Absolutely. It supports automatic temperature compensation via Pt100, Pt1000, or NTC 30K sensors, allowing standard linear, non-linear, or customizable compensation tables.
Q3: Is the CLM223 suitable for pharmaceutical ultrapure water testing?
A: Yes, the unit includes specialized software functions for monitoring Purified Water (PW) and Water for Injection (WFI) according to international USP and EP pharmacopoeia standards.
