Endress+Hauser is launching the Memosens digital pH sensors with conductivity and DO sensors as an analytical measuring point solution.

Memosens digital sensors enable process data to be saved directly in the sensor.This inductive, two-way data transfer between sensor and transmitter enables interference-free measuring signals.

It eliminates issues such as moisture ingress, leakages, corrosion, salt bridges, ground loops and handling via an inductive non-contact, plug-in connection that offers complete galvanic isolation.

The Memocheck Plus qualification tool verifies this data transmission independently of the sensor.

With five plug-in heads (each traceable back to production via a serial number), each simulating a particular sensor status, Memocheck makes measurement integrity watertight.

The Memosens integrated circuit board enables manufacturing data, current sensor properties and sensor history to be recorded and used as the basis for predictive maintenance.

Calibration data is stored, along with other key information such as overall time in operation, and minimum/maximum pH value and temperature.

Memosens sensors can be pre-calibrated under laboratory conditions and then quickly replaced at the measuring point.

The sensors identify themselves within the application and each measuring point recognises its individual sensor.

Memosens also offers a longer life because sensors can be checked and regenerated by cleaning in the laboratory.

Its pre-calibration also means that calibration under soiled or moist conditions is unnecessary and cuts work in hazardous areas to a minimum.

The Memocheck CYP02D service tool provides a quick and easy test of wiring and installation.

It can also be used onsite to troubleshoot a system that has already been commissioned, to establish possible causes of error.
