The Data Logger

Prior to use, it must be configured and then activated.

The following logging types can be selected:

–  Manual logging by pressing the softkey

–  Time-controlled logging at a fixed interval

–  Signal-controlled logging of measured value and temperature

–  Combined time- and signal-controlled logging

–  Threshold-controlled logging with pre-trigger 

The data logger records up to 10,000 entries, which can be assigned to different measuring points (TAGs) and annotations.

Portavo 9

The following data will be recorded: meas. point, annotation, sensor ID, serial number of sensor (Memosens), primary value, temperature, time stamp, device status.

The Paraly SW 112 software allows convenient management of the data logger. It is always the currently selected process variable which is recorded.

The Software

The standard USB port allows connecting the Portavo to a computer.

The Paraly SW 112 software was specially developed for the Portavo to enable easy management of recorded values.

Configuration is clear and simple.

Using the integrated export function, the logged data can be easily transferred to Microsoft Excel for further processing.

The concept of using digital Memosens sensors is globally unique.

Memosens – The Benchmark for Digital Sensors

The Memosens inductive sensor connector system transfers both energy and data without contact between electrochemical sensors and analyzers. The integrated intelligence allows saving and evaluating sensor related data directly in the pH/ORP, conductivity or oxygen sensor.

Memosens sensors: 

SE715: Optical dissolved oxygen with memosens technology

SE715 memosens ODO

The digital, optical oxygen sensor stores the calibration values internaly and it’s ready for immediate measurement. The advantages of the fluorescence quenching method come to light in particular during mobile oxygen measuring:

  • no polarization delay - ready for measuring immediately
  • no oxygen consumption
  • independent of the flow
  • integrated monitoring of the membrane state
  • no electrolyte required

This makes mobile oxygen measuring more precise and extremely low maintenance. Calibration is performed directly in the integrated quiver of the Portavo 907 Multi Oxy. The SE 715 oxygen sensor with Memosens connector system requires low maintenance and is equipped with a temperature sensor. It is characterized by its high long-term stability, fast response and low flow dependence. The sensor is designed for simultaneous measurement of dissolved oxygen and temperature in industrial processes.
