Endress+Hauser CPS11E-AA7AAS2 PH Level Switch for Liquids Bulk Solids

The Endress+Hauser CPS11E-AA7AAS2 is a highly reliable, compact, and cost-effective capacitive level switch designed for point level detection in a wide range of industrial applications. This robust sensor is engineered to provide precise and maintenance-free monitoring of liquids, pastes, and granular bulk solids, making it an ideal solution for process automation and overfill/empty protection.

Key Features & Benefits:

Universal Application: Versatile design suitable for level detection of conductive and non-conductive liquids, adhesives, powders, and granules. The model with rod probe (AA7AAS2) is ideal for bulk solids and liquids.

Compact and Robust Design: With its small footprint and rugged PPS housing, the CPS11E is perfect for installations in limited spaces and harsh environments.

Simple Setup and Operation: Intuitive one-button calibration (TARE) ensures quick commissioning directly at the sensor without requiring additional tools or complex programming.

High Reliability & Maintenance-Free: No moving parts, ensuring long-term stability and reducing total cost of ownership. The robust construction resists buildup and process conditions.

Excellent Chemical Resistance: The PPS housing and probe materials offer high resistance to a broad spectrum of chemicals, acids, and alkalis.

Flexible Output Options: Features a reliable PNP transistor switch output for direct integration into control systems.

Hygienic Process Connections: Available with various thread types (e.g., G½", ¾" NPT) and clamp processes, facilitating easy installation in standard vessels.

Typical Applications:

Liquid Level Detection: Overfill prevention or dry-run protection in tanks, containers, and small vessels for water, chemicals, oils, and foods.

Bulk Solids Level Control: High/low level detection in silos, hoppers, or bins for plastics, granules, flour, cement, and other powders.

Interface Detection: Can be used to distinguish between two immiscible liquids with different dielectric constants.

Industries: Chemical, pharmaceutical, food & beverage, water & wastewater, plastics, and general manufacturing.
