Endress+Hauser Cleanfit CPA871 Brochure

Unrivaled Safety and Flexibility for Process Measurement

The Endress+Hauser Cleanfit CPA871 stands as a beacon of operational safety and adaptable functionality, meticulously engineered for a broad spectrum of standard and highly demanding industrial applications. This advanced retractable assembly is designed to eliminate the risk of medium leakage during critical phases such as operation, cleaning, and calibration, thereby providing unparalleled protection for both the process integrity and, crucially, the operating personnel. Its intelligent design features actively prevent the assembly from being introduced into the process without a sensor securely in place, and equally, prevent the sensor from accidentally retracting from its measuring position. This inherent safety mechanism underscores the CPA871’s commitment to minimizing operational hazards and ensuring a controlled, secure measuring environment. The adaptability of the Cleanfit CPA871 is further enhanced by its capacity to be configured with specific materials and lengths to precisely match the unique requirements of diverse applications, whether they involve extensive immersion depths in challenging sticky media, exposure to aggressive chemical environments, or operation within classified hazardous areas. This makes it an indispensable tool for industries where precision, reliability, and safety are paramount.

Tailored for Challenging Industrial Environments

The Cleanfit CPA871 has been specifically developed to address the stringent safety demands across a variety of critical industrial sectors. Its robust construction and intelligent features make it ideally suited for the water and wastewater industry, encompassing challenging seawater applications where corrosion and fouling are significant concerns. Within the chemical industry, its resilience against aggressive media and hazardous substances ensures reliable performance and operator safety. The oil and gas industry benefits from its durability and ability to withstand high pressures and temperatures, crucial for upstream, midstream, and downstream operations. Similarly, the power and energy sector, including power generation facilities and renewable energy installations, relies on the CPA871 for safe and accurate measurements in demanding process conditions. Furthermore, its certification and design considerations make it suitable for hazardous area applications, where the risk of ignition necessitates the highest levels of safety and material integrity. This wide-ranging applicability highlights the versatility and engineered robustness of the CPA871.

Advanced Design for Optimal Performance

The core of the Cleanfit CPA871’s superior performance lies in its intelligent design and robust construction. The assembly is available for pH, ORP, oxygen, and NIR sensors, with common diameters of 12 mm and various immersion lengths including 120 mm, 225 mm, and 360 mm, offering a flexible fit for different tank and piping configurations. A key benefit contributing to its suitability for demanding applications is the optional immersion chamber. This feature is specifically designed to mitigate issues encountered with sticky media, preventing build-up and ensuring uninterrupted sensor performance and accurate readings. The overall assembly boasts a robust design, with a strong steel support housing that guarantees exceptional mechanical stability, even under strenuous operating conditions. This structural integrity is fundamental to maintaining the safety and reliability of the measurement setup, providing peace of mind in critical industrial processes.

Uncompromising Safety Features for Assurance

Endress+Hauser’s commitment to operational safety is exemplified by the intelligent functions integrated into the Cleanfit CPA871. These built-in safeguards are designed to prevent potentially hazardous situations before they can occur. The system actively ensures that the retractable assembly cannot be moved into the process without a sensor correctly installed and secured. Conversely, it also prevents the sensor from inadvertently moving out of the process while it is in its active measuring position. This dual protection mechanism is critical for maintaining the integrity of both the measurement and the containment of the process medium. This level of inherent safety significantly reduces the risk of accidental medium release or sensor detachment, thereby enhancing overall plant safety and reducing the likelihood of costly downtime or environmental incidents. The CPA871 truly elevates safety standards for inline process measurements.

Versatile Material Selection and Process Adaptability

The Cleanfit CPA871 is engineered for exceptional flexibility, allowing for precise adaptation to a wide array of processes and challenging media. A comprehensive selection of process connections is available, including various flange standards (DN 40, DN50, DIN65, DN80, EN1092-1, ASME B16.5, 10K50, JIS B2220, 10K80), clamp connections (Clamp 2″, ISO2852, ASME BPE-2012, Clamp 2½”), and threaded connections (NPT 1½”, ISO 228 G1¼”). This extensive range ensures compatibility with virtually any existing piping or vessel setup. Furthermore, the wetted materials can be chosen to perfectly suit the specific process requirements. Options for seals include EPDM, FPM (Viton), and FFKM, providing resistance to a wide spectrum of chemicals and temperatures. The immersion tube, process connection, and service chamber can be fabricated from high-grade materials such as stainless steel 1.4404 (with a surface finish of Ra < 0.76), PEEK, Alloy C22 (with Ra < 0.76), PVDF, and conductive PVDF. This careful material selection capability makes the CPA871 ideal for corrosive media and ensures suitability for hazardous area applications where material compatibility is critical for safety and longevity.

Engineered for Extreme Conditions and Durability

The robust design of the Cleanfit CPA871 extends to its capacity to handle a wide range of process temperatures and pressures, further cementing its suitability for demanding industrial applications. The assembly can operate within a temperature range of -10 to 140 °C (14 to 284 °F) for most material configurations. For specific materials like PVDF and conductive PVDF, the operating temperature range is adjusted to -10 to 100 °C (14 to 212 °F) or slightly lower at 90 °C (194 °F) when the immersion chamber is utilized, reflecting the material’s thermal limitations. In terms of pressure, the CPA871 demonstrates impressive capabilities. Stainless steel, Alloy C22, and PEEK materials can withstand up to 16 bar (232 psi) at temperatures up to 140 °C (284 °F). For PVDF and conductive PVDF materials, the basic version is rated for 16 bar (232 psi) up to 100 °C (212 °F). When the immersion chamber version of these PVDF materials is employed, the pressure rating is adjusted to 4 bar (58 psi) up to 90 °C (194 °F), a specification that accounts for the specific mechanical properties and thermal expansion characteristics of the chosen materials under pressure.

Applications Across Key Industries

The Cleanfit CPA871 finds extensive and critical application across multiple core industrial sectors. In the water and wastewater industry, it is vital for monitoring pH, ORP, and dissolved oxygen in treatment plants, including challenging applications involving seawater, where its corrosion-resistant materials are essential. The chemical industry relies on the CPA871 for precise measurements in aggressive chemical processes, handling corrosive fluids, and in potentially hazardous environments, ensuring both product quality and operator safety. The oil and gas industry utilizes the CPA871 for monitoring in various stages of production and refining, where its robust design can withstand harsh conditions and high pressures. In the power and energy sector, it plays a role in monitoring boiler feedwater, cooling water, and other critical parameters in power generation facilities. Furthermore, its design for hazardous areas makes it indispensable for any application where flammable gases, vapors, or dusts may be present, ensuring the highest level of intrinsic safety. It is also a key component in the primaries and metals industry for process control and quality assurance.
