pH-Probe PHBL-25
The pH measurement is based upon
the millivolt potential between a measuring and a reference electrode.
These so-called half elements are brought together in a combined
electrode. A millivolt potential, which is dependent on the pH value
of the measuring soultion, arises at the glass membrane, which is
connected to the potential of the reference electrode.
Since
the reference electrode is filled with a solid electrolyte there
is no need for refilling. The two point calibration
is easily performed by push-button.
The
milivolt output per pH-unit varies with temperature. The integrated
temperature sensor automatically compensates the
actual reading for this change of slope.
The temperature
can be read from the transmitter display.
For
practical reasons, the measuring range of th Zullig sensor is between
pH2 and pH12.
The fully
encapsulated pre-amplifier delivers low resistance, stable
signal. This allows a large separation between the sensor and transmitter
with no degradation of the signal.
Mounting types
A large variety of probe configurations
is available. This ensures suitability and ease of mounting into
almost any application including insertion and pressurized applications
through a ball valve.
