General
Mounting location
Find a location that ensures easy accessibility for the later calibration.
The fastening must be secure and must ensure low vibration for the instrument.
The operating conditions (temperature, pressure, chemical composition of the
measuring material, etc.,) must not be allowed to damage the measuring sensor.
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.
Incident flow
No incident flow is required to make the conductivity sensor work, but is
recommended for fast, stable measurement values and to prevent the
accumulation of deposits. Structural measures must be taken to prevent flow
separation or gas bubbles in the measuring material.
Immersion length
The immersion length (EL) of the conductivity sensor must be in keeping with
the installation situation.
