Campo de aplicação
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.
Benefícios
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
