ANALYTICAL TRANSMITTERS

ANALYTICAL TRANSMITTERS Liquiline M CM42 is a modular two-wire transmitter for all areas of process engineering, Ex and non-Ex areas. For analog sensors: pH/ORP/conductivity/concentration/resistivity. For digital sensors: pH/ORP/oxygen/conductivity. Depending on the ordered version, Liquiline has one or two analog current outputs or it can be connected to field buses as per FOUNDATION Fieldbus, PROFIBUS PA and Hart protocol. Liquiline is developed acc. to the international safety standard IEC 61508.

Liquisys M CPM223

Liquisys M CPM223 is a transmitter for pH/ORP measurement. It is available as panel-mounted housing (CPM223) or field housing (CPM253). The transmitter is suitable for analog, digital and ISFET sensors. The modular design of the Liquisys M CPM223/253 allows easy adaption of the transmitter to a variety of customer requirements. Starting with the basic version for “measurement and alarm generation”, the transmitter can be equipped with additional software and hardware modules for special applications.
