Application

Hygienic and sterile applications (sterilizable, autoclavable)

  • Bioreactor/fermenter
  • Biotechnology
  • Pharmaceutical industry
  • Foods

With ATEX/IECEx, FM, CSA, NEPSI, FDA and USP approval for use in hazardous areas.

Your benefits
  • Biocompatibility with regard to cytotoxicity and bioreactivity has been tested successfully
  • Documentation to certify compliance with requirements of pharmaceutical industry with serial number of sensor (optional)
  • Durable inscription on shaft, verified as non-cytotoxic
  • Suitable for CIP/SIP cleaning, autoclavable, up to 140 C (284 F) depending on version
  • Pressurized reference, specially for fermentation processes
  • Integrated pressure indicator
  • Long-term stable reference with ion trap, resulting in a very long service life, bridging electrolyte free of silver ions
  • No change in color of gel
  • Ceramic diaphragm
  • Integrated temperature sensor for effective temperature compensation
  • No materials derived from animals were used in the manufacture of parts in contact with the process media
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 with the Memobase Plus CYZ71D
Measuring principle pH measurement

The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The membrane glass of the electrode delivers an electrochemical potential that depends on the pH value of the medium. This potential is generated by the selective penetration of H + ions through the outer layer of the membrane. An electrochemical boundary layer with an electric potential forms at this point. An integrated Ag/AgCl reference system serves as the required reference electrode. The transmitter converts the measured voltage into the corresponding pH value using the Nernst equation.

Measuring system

A complete measuring system consists of the following components at least:

  • pH electrode CPS171D
  • Transmitter, e.g. Liquiline M CM42, CM44x/R
  • Memosens data cable CYK10
  • Assembly, e.g. Unifit CPA442
