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
          

• 
  Primaries & Metal
          

Liquisys CPM253 features the following protocols and interfaces:

• 
  0/4...20 mA
          

• 
  HART
          

• 
  PROFIBUS DP
          

• 
  PROFIBUS PA
          

Benefits




More operational safety: Continuous process check system, customized alarm configuration,
proven Memosens interface for reliable sensor connection.


Reliable self-monitoring: Sensor check system for pH glass and reference, calibration
plausibility check.


Easy to operate and service: Intuitive user interface, hot plug & play with pre-calibrated
Memosens sensors, direct access for manual contact control.


Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm
or limit switch.


Fit for every application: Numerous extensions, such as P(ID) controller, timer, etc., allow
for flexible adaption to all processes.
