Endress+Hauser CM42-MEA000EAZ00

Liquiline M CM42 Memosens: pH/ORP, oxygen, conductivity

Analog sensors: pH/ORP, conductivity, concentration, resistivity

Application

Liquiline M CM42 is a modular two-wire transmitter for all

areas of process engineering.

Depending on the version ordered, Liquiline has one or two

analog current outputs. In addition, it can be connected to

fieldbuses in accordance with the FOUNDATION Fieldbus,

PROFIBUS PA and HART protocol.

The transmitter is suitable for pollution degree 3.

The highly robust plastic version and the hygienic stainless steel

version are tailored to the following applications:

• Chemical processes

• Pharmaceuticals industry

• Foodstuff technology

• Applications in hazardous areas

Your benefits
