Field of application

Liquiline M CM42 is the robust transmitter for pH/ORP, conductivity or oxygen measurement in all process applications. It is the best choice for demanding environments be it hygienic applications, hazardous areas or functional safety areas. Liquiline’s intuitive operating concept simplifies commissioning, handling, and maintenance saving you time every day. Easy switching of parameters and seamless system integration give you the flexibility to adapt it exactly to your measuring task.

The Liquiline CM42 transmitter is suitable for all process applications, for example in these industries and their utilities:

  • Chemicals

  • Food & Beverages

  • Life Sciences

  • Power & Energy

  • Oil & Gas

  • Primaries & Metal

Liquiline CM42 features the following protocols and interfaces:

  • 0/4...20 mA

  • HART

  • PROFIBUS PA

  • FOUNDATION Fieldbus

With its international explosion protection approvals, such as IECEx, ATEX, FM, CSA, TIIS and NEPSI, the transmitter is suitable for hazardous area use.

Benefits

  • Simple commissioning with quick setup and navigator

  • The Memosens technology allows plug & play with pre-calibrated Memosens sensors

  • Less storage thanks to modular design

  • Predictive maintenance system detects when a sensor has to be cleaned, calibrated or replaced

Videos

  • Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
