Endress+Hauser CM14-AAM Toroidal Conductivity Sensor 1-channel transmitter

The Endress+Hauser CM14-AAM is an industrial-grade toroidal (electrodeless) conductivity sensor designed for reliable measurement in challenging, high-fouling, and corrosive applications. As part of Endress+Hauser's trusted Liquiline portfolio, this sensor excels where traditional contacting sensors fail—particularly in fluids containing oils, suspended solids, fibers, or highly corrosive chemicals. Its electrodeless design eliminates polarization effects and electrode degradation, providing stable, low-maintenance operation in water treatment, chemical processing, mining, and food & beverage industries. We are pleased to confirm this model is currently in stock and available for fast shipment.

Key Features & Advantages

1. Fouling & Corrosion Resistance

The CM14-AAM’s fully encapsulated toroids are immune to coating, scaling, and chemical attack. Unlike electrode-based sensors, it maintains accuracy in dirty fluids, slurries, or solutions containing abrasive particles—reducing cleaning frequency and maintenance costs.

2. No Electrode Wear, Long-Term Stability

Since no metal electrodes contact the medium, issues like polarization, plating, or electrode dissolution are eliminated. This ensures exceptional long-term stability and repeatability, even in extreme conductive solutions.

3. Wide Measurement Range with One Sensor

Capable of measuring from low μS/cm to saturated brines (up to 2000 mS/cm), the CM14-AAM eliminates the need for multiple sensors or range switching. This versatility simplifies inventory and handles fluctuating process conditions.

4. Robust Construction for Harsh Environments

Constructed with chemical-resistant PPS housing and durable PEEK toroids, the sensor withstands high temperatures, pressures, and aggressive media. Its industrial design is built for continuous duty in outdoor or washdown areas.

5. Easy Integration & Reduced Lifetime Cost

Compatible with a wide range of transmitters, the sensor installs quickly with standard process connections. Minimal maintenance and no replacement electrodes translate to significantly lower total cost of ownership over years of service.

Ideal Applications

Cooling Water & Brine Monitoring: High-concentration salt measurement without sensor degradation.

Chemical Concentration Control: Acid, caustic, or solvent concentration in process streams.

Wastewater & Scrubber Solutions: Reliable measurement in slurries and fouling liquids.

Food & Beverage: CIP (cleaning-in-place) and lyc concentration monitoring.

Pulp & Paper: Black/green liquor and chemical recovery applications.
