Field of application

Liquisys CPM253 is a standard pH/ORP transmitter for all analog and digital Memosens sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and two-point calibration make configuration and operation fast and easy.

The Liquisys CPM253 transmitter works with all pH/ORP glass and ISFET sensors in non-hazardous areas, for example in these industries and their utilities:

  • Chemicals

  • Food & Beverages

  • Power & Energy

  • Water, Wastewater & Waste

  • Primaries & Metal

Liquisys CPM253 features the following protocols and interfaces:

  • 0/4...20 mA

  • HART

  • PROFIBUS DP

  • PROFIBUS PA

Benefits
