Endress+Hauser CPS11E-BA7AAA2 Capacitive Level Switch

Endress+Hauser CPS11E-BA7AAA2: Capacitive Level Switch for Reliable Point Level Detection

The Endress+Hauser CPS11E-BA7AAA2 is a high-performance, hygienic capacitive level switch designed for precise point level detection in liquids, pastes, and granular solids. As part of the proven CPS platform, this model ensures reliable process safety and efficiency in demanding industrial applications.

Key Features and Benefits

Versatile Detection: Reliable detection of liquids, viscous media, and powders. Ideal for interfaces (e.g., oil/water) and foam detection.

Hygienic Design: Features a PTFE (Teflon®) probe with a smooth surface and 316L stainless steel process connection. Perfect for food & beverage, pharmaceutical, and sanitary applications. The BA7AAA2 variant specifies a G ¾" A external thread with a PTFE seal.

Easy Installation and Setup: Simple commissioning via intuitive push-button programming without needing to open the housing. Flexible mounting in horizontal, vertical, or angled orientations.

Robust and Maintenance-Free: No moving parts, ensuring long-term stability and reduced maintenance. The rugged housing (protection class IP66/IP68) withstands harsh environments.

High Process Compatibility: Withstands high pressures (up to 40 bar) and temperatures (up to 100°C / 212°F at the sensing rod). Excellent chemical resistance thanks to the PTFE coating.
