Your benefits
  • Sensor version suitable for pharmaceutical industry:
    • Stainless steel 1.4435 (AISI 316L)
    • Sterilizable and autoclavable
  • Application-specific versions:
    • Sensor for standard applications, e.g. for fermenter control
    • Trace sensor, e.g. for use in the power station sector and for the beverage industry (CO2-compatible sensor)
  • Very versatile:
    • Standard process connection Pg 13.5
    • Installation possible in standard pH assemblies
  • Short response time: t 98 < 60 s
  • Integrated temperature sensor
Other advantages of Memosens technology
  • Maximum process safety thanks to non-contact, inductive signal transmission
  • Data security thanks to digital data transmission
  • Very easy to use as sensor data saved in the sensor
  • Recording of sensor load data in the sensor enables predictive maintenance
Measuring principle

The oxygen molecules that diffuse through the membrane are reduced at the cathode to hydroxide ions (OH-). At the anode, silver is oxidized to silver ions (Ag+) (this forms a silver halide layer). A current flows due to the electron donation at the cathode and the electron acceptance at the anode. Under constant conditions, this flow is proportional to the oxygen content of the medium. This current is converted in the transmitter and indicated on the display as an oxygen concentration in mg/l, μg/l, ppm, ppb or Vol%, as a saturation index in % SAT or as an oxygen partial pressure in hPa.
