The Endress+Hauser Memosens CPS71E is a digital pH sensor designed specifically for challenging industrial processes [1]. Here’s a breakdown of its key features:

• Built for Tough Environments: This sensor excels in heavily polluted and aggressive media, including strong acids and bases, due to its unique contamination-resistant reference and moisture resistance [1]. This ensures reliable readings even in harsh conditions.
• Memosens 2.0 Technology: This advanced digital technology offers several advantages:
  • Predictive Maintenance: Extended storage of calibration and process data allows for trend identification, forming the basis for preventative maintenance strategies and maximizing process uptime [1].
  • Fast Sensor Exchange: Pre-calibration in a lab setting enables quick and easy sensor replacement on-site, minimizing downtime [1].
• Applications: Ideal for monitoring processes with:
  • Rapidly changing pH values [1].
  • High presence of electrode poisons like H2S (hydrogen sulfide) [1].
• Technical Specifications:
  • Measurement principle: Potentiometric [1].
  • Measuring Range (Application B): 0 – 14 pH [1].
  • Process Temperature: 32 to 284°F (1 to 140°C) [1].
  • Process Pressure: 0.8 to 14 bar (11.6 to 203 psi) [1].
  • Material: Sensor shaft made from process-suited glass [1].
  • Connection: Inductive, contactless Memosens 2.0 connection head [1].
  • Ex approvals for use in hazardous areas (consult Endress+Hauser for details) [1].

In summary, the Endress+Hauser Memosens CPS71E is a digital pH sensor designed for reliable and accurate measurements in demanding industrial applications. Its focus on contamination resistance, digital intelligence, and fast sensor exchange makes it a valuable tool for process control and optimization.
