Endress+Hauser CM42-CAA000EAD00 Sanitary All-Metal Inductive Conductivity Sensor

Endress+Hauser CM42-CAA000EAD00: The Hyienic Inductive Conductivity Sensor for Critical Processes

The Endress+Hauser CM42-CAA000EAD00 is a premium, all-metallic inductive conductivity sensor (also known as a toroidal or electrodeless sensor) engineered for the most demanding sanitary, sterile, and highly corrosive applications. Its robust design and hygienic construction make it the ideal choice for industries where process integrity, cleanability, and reliability are non-negotiable.

Core Benefits & Why It's the Superior Choice

1. Unmatched Hygiene & Cleanability

CIP/SIP Ready: Perfectly suited for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) processes. The smooth, crevice-free PEEK body and all-welded 316L stainless steel housing prevent product entrapment and bacterial growth.

FDA-Compliant Materials: Constructed with materials approved for contact with food, beverages, and pharmaceuticals, ensuring compliance with strict industry regulations.

Optimal Drainage: The sensor's design promotes complete drainage, eliminating dead zones and ensuring effective cleaning.

2. Ultimate Durability & No Maintenance

Inductive (Electrodeless) Principle: Unlike contacting sensors, the CM42 has no exposed electrodes to foul, corrode, or degrade. This makes it immune to coating, corrosion, and polarization effects, significantly reducing maintenance and downtime.

All-Welded, Hermetically Sealed Housing: Provides exceptional protection against moisture ingress and mechanical stress, ensuring long-term stability and reliability even in harsh environments.

3. Exceptional Measurement Performance

Wide Measuring Range: Accurately measures conductivity from µS/cm up to high mS/cm ranges, suitable for a vast array of applications from ultra-pure water to concentrated solutions.

High Temperature & Pressure Resistance: Built to withstand the rigors of high-temperature cleaning and demanding process conditions.
