The Endress+Hauser Memosens digital sensor can be combined with the Liquiline M transmitter to reliably measure pH, conductivity and DO.

Memosens saves process data, guaranteeing interference-free measuring signals and simplification of process-measuring technology.

The Memosens inductive plug-in connection and bayonet-lock eliminates the problems of moisture ingress, leakages and corrosion, offering complete galvanic isolation.

Liquiline is available as a digital or analogue transmitter and is compatible with all standard bus systems such as HART, Profibus or Foundation Fieldbus.

When Liquiline is used in combination with Memosens, sensor-specific data is automatically transmitted between sensor and transmitter.

Critical data (for example calibration data and sensor limits) is stored in the transmitter, allowing simple commissioning and maintenance with pre-calibrated sensors.

Memosens sensors can be pre-calibrated in a laboratory and then replaced in the measuring point, eliminating the problems associated with difficult-to-access measuring points.

The sensors identify themselves within the application: each measuring point recognises its individual sensor, reducing downtime.
