Field of application

The Memosens CPS71E is designed for demanding processes. Its contamination-resistant reference and moisture resistance ensure reliable measurements in heavily contaminated, aggressive media such as strong acids and bases. With Memosens 2.0 digital technology, the CPS71E increases the storage capacity for calibration and process data and supports predictive maintenance. Laboratory calibration and quick on-site sensor replacement maximize process uptime.

Features

  • The special ion trap of the electrode prevents poisoning of the junction and the reference, offers resistance to strong acids and bases and ensures a longer service life of the sensor.
  • The optional pressurized reference ensures reliable measurements in blocking media.
  • Optional upside-down mounting for flexible installation.
  • Inductive cable connection and non-contact signal transmission improve process integrity by preventing problems with moisture or corrosion.
  • On-site sensor replacement minimizes process downtime and costs.
  • Memosens 2.0 technology enables trend identification, predictive maintenance and advanced IIoT services with extended data storage for calibration and process information.
