pH/Redox
Symmetric connection of a combination electrode with
integrated resistance thermometer and VarioPin plug
head
Symmetric connection is used to reduce interference from
stray electromagnetic fields along the sensor cable.
The RTD temperature probe is used to provide a tempera-
ture-compensated pH-value measurement, and can be con-
nected to a temperature input or universal input.
A = Glass/metal electrode (core)
B = Reference electrode (inner shield)
C = Liquid potential (grounding pin, pipe, or container wall at
the measuring point)
D = Shield (outer shield)
E = RTD temperature probe
F = RTD temperature probe
G = RTD temperature probe
Terminal 2 is not connected!
