Technicaldata
Max. fluid temperature The fluid temperature may be
restricted by the probe used (see the
related instruction manual), by the
pressure of the fluid and the material
of the adapter S022
See Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
Max. fluid pressure PN16
The fluid pressure may be restricted
by the probe used (see the related
instruction manual), by the tempe-
rature of the fluid and the material of
the adapter S022.
See Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
ph measurement (8202)

• Recommended min.
divergence of the pH
range associated to the
4-20 mA signal
range 6,7 to 7,2 pH or -20 mV
to +10 mV associated to the
4-20 mA output current)
