CPS91D-7BT2G ENDRESS+HAUSER Orbipore

The ENDRESS+HAUSER Orbipore CPS91D (Specific Part Code: CPS91D-7BT2G) is a digital pH sensor designed for heavy-duty industrial monitoring in highly contaminated media. It features an open aperture junction rather than a traditional porous ceramic or PTFE junction, making it practically immune to clogging from suspended solids, fibrous particles, or thick emulsions.

Equipped with Memosens digital technology, this sensor handles data processing directly within the inductive plug head, eliminating signal distortion from moisture and environment interference.

Technical Breakdown of Code: CPS91D-7BT2G

The order structure details the exact specifications of this electrode:

• CPS91D: High-solids Orbipore pH sensor with digital Memosens technology.

• BT: Application Range / Temperature Limits: Heavy-duty applications. Designed for temperatures ranging from 0°C to 110°C (32°F to 230°F) and absolute pressures up to 14 bar (203 psi).

• 2: Shaft Length: Standard 120 mm insertion shaft length.

• G: Integrated Temperature Sensor: Built-in Pt100 temperature element for precise, automated temperature compensation during measurement loops.

Key Technical Specifications

• Measuring Range: 0 to 14 pH

• Process Temperature Range: 0°C to 110°C (32°F to 230°F)

• Maximum Process Pressure: 1 to 14 bar (15 to 203 psi) absolute pressure

• Reference System: Redundant double-gel reference system with highly stabilized electrolyte gel.

• Junction Design: Open aperture (direct contact between the sample medium and the gel reference).

• Sensor Material: Glass body with specialized Type B pH-sensitive membrane glass.

• Connection Type: Inductive, non-contact Memosens plug head (IP68 rated).

• Shaft Diameter: 12 mm

• Shaft Length: 120 mm

   Advantages for Processing Lines

• Open Aperture Clogging Protection: Traditional porous diaphragms trap fibers and oils, leading to rapid sensor fouling and signal drift. The open aperture design exposes the gel bridge directly to the medium, making it the primary choice for the pulp and paper industry, chemical precipitation reactions, and wastewater containing high levels of suspended sludge
