Endress+Hauser CPS11D CPS11E OEM Pressure Sensor BA7BAA2 Variant High Accuracy

The Endress+Hauser CPS11E-BA7BAA2 is a premium, capacitive OEM pressure transmitter belonging to the renowned CPS11 series. Designed for original equipment manufacturers (OEMs) and system integrators, this compact sensor delivers exceptional accuracy and long-term stability in a robust, ceramic-measuring cell package. Its variant code BA7BAA2 specifies key parameters like pressure range, output signal, and electrical connection, making it ideal for customized integration into medical equipment, industrial machinery, hydraulics, and process applications.

Core Features & Benefits

Ceramic CAP-Cell Technology: The heart of the CPS11E is its durable, ceramic measuring cell. It provides excellent resistance to overpressure, corrosion, and aggressive media, ensuring a long service life and reduced maintenance.

High Accuracy & Stability: Offers outstanding measuring performance with high accuracy and minimal long-term drift. This reliability is critical for precision applications in testing, monitoring, and control systems.

Exceptional Media Compatibility: Thanks to the fully ceramic, gold-plated measuring diaphragm, the sensor is compatible with a wide range of media, including corrosive, viscous, or dirty fluids. It is also suitable for use with non-conductive gases.

Compact & Lightweight Design: Its small form factor and low weight make the CPS11E-BA7BAA2 perfect for space-constrained installations and mobile equipment.

Flexible OEM Integration: Designed specifically for integration into larger systems. The variant-specific coding (like BA7BAA2) allows for precise selection of pressure range, output (e.g., 0.5...4.5 V ratiometric), and plug connection, simplifying the design-in process.

Robust & Maintenance-Free: With no moving parts and a welded housing, the sensor is extremely robust, vibration-resistant, and requires no recalibration under normal operating conditions.
