Endress+Hauser CPS11E-NA7ATA2 Compact Ceramic Pressure Sensor

Endress+Hauser CPS11E-NA7ATA2 – Compact Ceramic Pressure Sensor for Water and Wastewater Applications

Subtitle: Robust, Maintenance-Free Pressure Measurement for Level and Process

The Endress+Hauser CPS11E-NA7ATA2 is a high-performance, compact ceramic pressure sensor engineered for reliable and cost-effective level and pressure measurement in water, wastewater, and general industrial services. Its unique ceramic measuring cell and robust design ensure long-term stability even in harsh, abrasive, or corrosive media.

Key Features & Benefits:

Advanced Ceramic Measuring Cell: The heart of the CPS11E is its patented, capacitive CERAMIC sensor. It is highly resistant to abrasion, corrosion, and clogging, making it ideal for demanding liquids like raw sewage, sludge, and process water. It requires no maintenance and offers exceptional long-term stability.

All-Welded Stainless Steel Housing (NA7): The NA7 version features a fully welded, stainless steel (316L) housing and process connection. This hermetically sealed design provides superior ingress protection (IP68/IP69K) and ensures maximum reliability in outdoor, washdown, or submerged environments.

Integrated Temperature Sensor (TA2): The "TA2" suffix indicates a built-in Pt1000 temperature sensor. This allows for automatic temperature compensation of the pressure measurement, ensuring high accuracy across the entire operating temperature range. It also provides an additional temperature output for process monitoring.

Compact and Versatile Design: With its compact dimensions and lightweight construction, the CPS11E is easy to install in confined spaces, directly on pipes, tanks, or open channels. It is suitable for measuring level in wells, basins, and tanks, as well as for pump control and filter monitoring.

Simple Configuration and Diagnostics: The sensor is configured via the intuitive Endress+Hauser "Commuwin II" software or directly via the display of many Endress+Hauser transmitters. Integrated diagnostics monitor the sensor's health, promoting predictive maintenance and reducing downtime.

Global Approvals: The CPS11 series carries important international approvals (e.g., CE, EAC, RoHS), facilitating use in projects worldwide.
