Endress+Hauser Digital combined pH/ORP sensor Memosens CPS96E

Overview of Memosens CPS96E

The Memosens CPS96E by Endress+Hauser is a high-performance, digital combined sensor designed for simultaneous pH, ORP (redox), and rH (in rH mode) measurements

Key Specifications

• Measurement Ranges:
• ORP: –1,500 mV to +1,500 mV
• pH: 0 to 14
• Process Temperature: 0 – 110 °C (32 – 230 °F)
• Process Pressure: 0.8 – 14 bar absolute (approx. 11.6 – 203 psi)
• Ingress Protection: IP68 rated for robust environmental sealing
• Sensor Materials:
• Shaft: Glass suited to processes
• pH membrane: Type B glass
• Reference system: Ag/AgCl with stabilized gel and ion trap
• ORP electrode: Platinum disc
• Seals: FKM O-rings, PPS fiber-glass reinforced coupling, ceramic metal oxide nameplate

Distinctive Features & Advantages

• Open-Aperture Design: Reduces fouling and avoids diffusion potential build-up—ideal for media with high levels of suspended solids such as dispersions, emulsions, and precipitates
• Memosens 2.0 Technology:
• Digital, inductive signal transmission (non-contact) ensures reliable, moisture-resistant data transfer
• Supports lab calibration and stores extensive calibration and process data, enabling trend analysis and predictive maintenance—perfect for IIoT integration
• Sensor Quality Monitoring: Includes a platinum electrode to monitor reference impedance continuously, helping detect deterioration or poisoning
• Robust & Poisoning-Resistant: Stabilized gel with ion trap protects reference system from contamination
• High Process Safety: Digital inductive coupling removes the need for direct electrical contacts, enhancing safety in hazardous environments
• Certification for Hazardous Zones: ATEX, IECEx, CSA C/US, NEPSI, Japan-Ex, and INMETRO approvals—suitable for Zones 0, 1, and 2

Typical Applications

The CPS96E is engineered for challenging, contaminated, or solid-laden media, making it a go-to for:

• Chemical processes
• Pulp and paper industry
• Paint and flue gas cleaning
• Media with dispersions, precipitations, emulsions, or general contamination
