Endress+Hauser CPS11E-BA7BTA2 Precision Conductivity Sensor

Endress+Hauser CPS11E-BA7BTA2: Precision Conductivity Sensor for Water and Wastewater Applications

The Endress+Hauser CPS11E-BA7BTA2 is a robust and high-performance 4-electrode conductivity sensor designed for reliable measurement in demanding water and wastewater treatment processes. Its advanced design ensures long-term stability, minimal maintenance, and accurate data critical for process control and quality monitoring.

Product Overview & Key Features

The CPS11E-BA7BTA2 is part of Endress+Hauser's innovative Liquiline platform, integrating seamlessly with transmitters like the CM44x for a complete analytical measurement solution. This sensor is engineered for applications where build-up, corrosion, or harsh chemicals are a challenge.

4-Electrode Measurement Principle:

Delivers highly accurate and stable conductivity readings, independent of cable length and sensor fouling.

Eliminates polarization effects, ensuring reliable measurements across a wide range (0 ... 2000 µS/cm).

Robust BA7BTA2 Sensor Body (PPS/PTFE):

Constructed from corrosion-resistant PPS with a PTFE-coated stainless steel shaft, ideal for aggressive media in chemical dosing, filtration, and neutralization stages.

Temperature Compensation (Integrated Pt1000):

Features a built-in Pt1000 temperature sensor for precise automatic temperature compensation (ATC), vital for accurate conductivity readings.

Easy Integration & Maintenance:

Standard M12 connector (BA7BTA2 variant) ensures quick, plug-and-play installation and connection to compatible Liquiline transmitters.

The open, cage-like design minimizes build-up and allows for easy cleaning.

Primary Applications

This sensor is perfect for monitoring water quality and process stages in:

Drinking & Ultrapure Water Treatment: Monitoring reverse osmosis (RO) permeate, demineralization, and distribution.

Wastewater Treatment: Controlling conductivity in effluent, neutralization processes, and recycling streams.

Industrial Water Management: Cooling water blow-down control, boiler feedwater monitoring, and leak detection.
