Function
LRG 16-40, LRG 17-40
A measuring current of variable frequency flows through the
fluid and creates a potential gradient between the measuring
electrode and the measuring tube. The potential gradient is
evaluated as measuring voltage UU.
LRG 16-41
The conductivity electrode consists of two current and
two voltage electrodes. The current electrodes send the
measuring current UI
with a fixed frequency into the fluid, thereby creating a potential gradiant between these
electrodes. This potential gradiant is then detected by the
voltage electrodes and evaluated as measuring voltage UU.
Thanks to this process insulating layers and polarization
effects will be compensated. Technical Data
Test approval no.
