Page 6: Description
1 µS/cm to 600 mS/cm, with just one measuring sensor. The hygienic design of the sensor and the EHEDG-certified system for process connection (JUMO PEKA), mean that it can be used in pharmaceutical and food technology without difficulty. JUMO PEKA is an adapter system that combines the measuring sensor with the process connection. - Page 7 2 Description Function current/voltage control voltage/current voltage voltage measurement The measuring sensors have two pairs of electrodes. The transmitter applies alternating current at the outer pair of electrodes. A voltage is released at the inner electrodes - subject to the conductivity of the measuring material. The transmitter acquires the voltage and uses it to calculate the electrolytic conductivity value.

Page 10: Mounting
The measuring sensor must not be modified mechanically (e.g. shortened, drilled, ground). A minimum distance of at least two meters must be maintained when installing several JUMO tecLine CR-4P type conductivity sensors. Installation position The conductivity sensor can be mounted in any position. But it is essential to make sure that the measuring sensor electrodes are fully immersed in the measuring material. -

Page 19: Calibration
General JUMO tecLine CR-4P conductivity sensors are exactly gaged at the factory. The cell constant of every measuring sensor is documented both on the cell stem and on the calibration certificate that is also supplied. -
Page 20: Maintenance/Troubleshooting
7 Maintenance/troubleshooting Cleaning the conductivity sensor Conductive conductivity sensors are not authorized for use in highly adherent, oily or glutinous media - we recommend using our inductive conductivity measuring instruments here! After cleaning the conductivity sensor, always rinse it with water! The conductive conductivity sensor electrodes are in direct contact with the measurement medium. -
Page 21: Troubleshooting
7 Maintenance/troubleshooting Troubleshooting Troubleshooting must always consider all the components of the conductivity measurement chain! The transmitter and the connecting cable must also be tested, as well as the conductivity sensor. Error Possible cause Remedy Measurement value Conductivity sensor is Clean the conductivity is too high or too low dirty... -
Page 22: Technical Data
The measured cell constant is recorded on the stem of the conductivity sensor. A cell constant deviation can be adjusted at the transmitter. The CR-4P cable is required for connection (see section 5.3 "CR-4P cable") See 4.2 "JUMO PEKA process connection adapter" and data sheet 409711. - Page 24 JUMO GmbH & Co. KG JUMO Instrument Co. Ltd.
