Technical data
6.5 Fluid data
Pipe diameter
DN25 to DN110
(DN15 to DN20 under specific conditions)
Type of fitting
Type S022
Nut between the 8222 and the fitting
G 1 1/2'' internal thread
Fluid temperature
The fluid temperature may be restricted by the fluid
pressure, the material of the nut and the material of the
fitting used.
• with a PVDF nut (see Fig. 3 and Fig. 5) • –20...+100 °C
• with a PVC nut (Fig. 3 and Fig. 4) • 0...+50 °C
Fluid pressure
2) not evaluated by UL
PN16
2)
The fluid pressure may be restricted by the fluid
temperature, the material of the nut and the material of
the fitting used. Refer to Fig. 3, Fig. 4 and Fig. 5.
Conductivity measurement
• Measurement range • 0,05 µS/cm...10 mS/cm
• Resolution • 1 nS/cm
• Measurement deviation • ±3 % of the measured value
• Recommended min. divergence of the conductivity
range associated to the 4...20 mA signal
• 2 % of the full scale (e.g. for the sensor with C=0.1:
range from 100...104 µS corresponds to the
4...20 mA output current)
Temperature probe
Pt1000 integrated in the conductivity sensor
Temperature measurement
• Measurement range • –40...+130 °C
• Resolution • 0.1 °C
• Measurement deviation • ±1 °C
• Recommended min. divergence of the temperature
range associated to the 4...20 mA signal
• 10 °C (e.g. range +10...+20 °C corresponds to the
4...20 mA output current)
Temperature compensation
• no compensation
• compensation according to a predefined curve: NaCl
or ultra pure water
• compensation according to a curve defined espe-
