Description

Endress+Hauser CPA450 Manual Retractable Assembly Cleanfit

The Endress+Hauser CPA450 retractable assembly is the accessible entry point into manual sensor retraction technology. It is engineered specifically for installation in thick-walled tanks and large pipes, where conventional inline fittings are impractical. Its defining feature is an integrated stainless steel ball valve that seals the process reliably. Because of this design, sensors can be withdrawn for cleaning, calibration, or replacement without interrupting production or emptying the vessel. For plants that depend on continuous liquid analysis, this single advantage translates directly into measurable maintenance savings.

Key Features and Benefits

Reliable Process Separation

The manually operated ball valve creates a secure mechanical barrier between the process and the sensor. Maintenance teams can retract the electrode safely even while the vessel remains under pressure. This protects both personnel and equipment, and it removes the need for costly shutdown procedures. The valve body is manufactured from high-grade stainless steel, ensuring dependable sealing performance across years of repetitive service cycles.

Variable Immersion Depth up to 700 mm

Flexibility is another core strength of the Endress+Hauser CPA450 retractable assembly. The immersion depth is adjustable up to 700 mm, so the electrode can always be positioned at the optimal point in the tank or pipe. Whether your application involves an open or closed vessel, the assembly adapts to the geometry of the installation rather than forcing compromises in measurement quality.

Robust Material Selection

Aggressive and coating-prone media demand carefully chosen materials. The immersion tube is available in stainless steel 1.4404, Alloy C22, or titanium 3.7035, while O-ring options include EPDM, Viton, and Kalrez. This combination allows the assembly to withstand fibrous media, abrasive slurries, and highly corrosive chemicals. The rinse chamber connection (G 1/4″) further supports cleaning and calibration routines directly at the assembly.

Typical Applications and Industries

The Endress+Hauser CPA450 retractable assembly is proven across a wide range of demanding industries. In the chemical industry, it handles corrosive process streams safely. Pulp and paper mills benefit from its resistance to fibrous stock and coating formation. Power plants and industrial water treatment facilities rely on it for continuous monitoring, while wastewater treatment operations value its tolerance of fouling media. In every case, the assembly keeps measurement points alive without stopping the process.

Installation and Integration Advantages

Broad Process Connection Compatibility

Integration into existing plant infrastructure is straightforward. Thread connections are available in G 1 1/4″ and NPT 1 1/4″, while flange options include DN32 PN16 and ASME 1 1/4″. This breadth of fittings means the assembly can be matched to virtually any tank nozzle or pipe section, simplifying retrofit projects and new installations alike.

Operating Envelope and Safety

The assembly is rated for process pressures up to 12 bar at 100 °C and process temperatures from -15 to 130 °C. It accommodates standard 120 mm electrodes and is supplied with documentation according to 3.1B EN 10204, supporting quality assurance requirements in regulated environments. Together, these characteristics make it a dependable foundation for potentiometric measurement points.
