Endress+Hauser CPS11E-AA7FAA2 Compact Capacitive Point Level Switch

The Endress+Hauser CPS11E-AA7FAA2 is a robust and reliable compact capacitive point level switch designed for high and low-level detection in liquids, pastes, and slurry applications. Part of the proven CPS line, this model ensures process safety and efficiency in demanding industrial environments.

Key Features & Benefits:

Universal Application: Suitable for liquids, conductive and non-conductive media, as well as adhesives and aggressive process fluids (with compatible PFA or Teflon-coated probe). The "AA" in the suffix often indicates a standard rod probe.

Compact Design: Its small size and threaded (e.g., G1" or 1" NPT) process connection make it easy to install even in tight spaces or directly into nozzles and small vessels.

Simple Setup & Operation: Features intuitive one-button calibration (Teach-in) for fast, error-free configuration directly at the device. No complex adjustments are needed.

High Reliability: Immune to product buildup, bubbles, foam, and variations in pressure, temperature, or density. This ensures consistent and false-trip-free switching.

Robust Construction: The housing is typically made of durable plastic (e.g., PPSU) or stainless steel, offering high chemical resistance and protection ratings up to IP66/IP67.

Clear Status Indication: Integrated LED provides clear visual feedback on switching status and device condition.

Technical Specifications (General):

Operating Principle: Capacitive

Output: Typically, 1 PNP/NPN transistor switching output or a relay variant.

Process Connection: Common thread types like G1" or 1" NPT.

Process Temperature Range: Typically -40 to +130 °C (-40 to +266 °F), probe-dependent.

Process Pressure Range: Up to 40 bar (580 psi), probe-dependent.

Electrical Connection: M12 x1 connector or cable gland.

Certifications: Often carries approvals like SIL2 according to IEC 61508, CE, and others for use in safety-related applications.

Typical Industries & Applications:

Chemical & Petrochemical: Level control in tanks, vessels, and containers.

Pharma & Food & Beverage: High/low-level detection in mixing tanks, reactors, and storage vessels.

Water & Wastewater: Pump control and dry-run protection.

Machine Building: Level monitoring in hydraulic units, lubricant reservoirs, and coolant tanks.

General Industry: Reliable point level detection in sumps, skids, and mobile equipment.
