Extended Extended

Memosens CLS15E is perfectly suited for conductivity measurement in applications with low measuring ranges such as boiler feedwater and chip cleaning. The contacting conductivity sensor performs reliably and accurately even in hazardous areas. CLS15E features Memosens 2.0 digital technology, offering extended storage of calibration, adjustment and process data. It facilitates predictive maintenance and provides the perfect basis for IIoT services.

Memosens CLS15E measures conductivity in pure and ultrapure water applications for the monitoring and control of:

  • Boiler feedwater
  • Ion exchangers
  • Reverse osmosis
  • Cooling water
  • Distillation
  • Chip cleaning

The digital sensor can be used in power plants for:

  • Degassed conductivity
  • pH measurement with differential conductivity

With its international explosion protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.

Features
  • Designed for low maintenance and a long operating life, the sensor offers best value for money.
  • The sensor is sterilizable and autoclavable, allowing for installation in sterile plants.
  • Thanks to its electrode geometry, Memosens CLS15E provides reliable and accurate measured values at low conductivities.
  • A quality certificate stating the individual cell constant enables perfect adjustment of the measuring point.
  • IIoT ready: Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
  • Non-contact inductive signal transmission ensures maximum process safety.
