Endress+Hauser CPS11E-AA7BAA2: The Compact Capacitance Sensor for Reliable Level Monitoring

The Endress+Hauser CPS11E-AA7BAA2 is a robust and versatile compact capacitance point level sensor designed for high-performance detection of liquids, pastes, and slurries in demanding industrial applications. As a key component in process automation, it ensures safety, efficiency, and reliability.

Product Overview & Core Benefits

The CPS11E series, including the AA7BAA2 variant, is engineered for simplicity and durability. Its compact design allows for easy installation even in confined spaces, making it an ideal solution for a wide range of industries from chemical and pharmaceutical to water treatment and food & beverage.

Universal Application: Suitable for point level detection (high or low alarm) in conductive and non-conductive media.

Robust Construction: Features a sturdy PFA sheath probe and an aluminum housing (protection class IP66/67), ensuring excellent resistance to corrosion, aggressive chemicals, and harsh process conditions.

Easy Installation & Setup: The compact design and simple 2-wire connection with plug-in electronics enable quick commissioning and reduced maintenance time.

High Reliability: Immune to product buildup, bubbles, foam, and turbulence due to its advanced signal evaluation technology, guaranteeing stable switching points and preventing false alarms.

Flexible Options: The "AA7BAA2" designation indicates specific factory-set parameters such as a fixed sensing length, process connection (e.g., G¾ thread), and electrical connection (M12 plug). Various other configurations are available to match exact process needs.
